Features

Slim and robust unit body resists twisting, warping and impact

Downsized internal unit, increased case thickness

The internal unit was redesigned and downsized extensively.
The internal unit was downsized to less than 40% (volume ratio) as compared to the conventional model while achieving higher performance.
The case structure was also optimized and offers high rigidity without any change in external dimensions.
The SF4D series provides high performance and high reliability while maintaining the installation and wiring compatibility with the previous models.

Mounting brackets feature both rigidity and ease of handling

Completely new mounting brackets and structure. In addition to strengthening the rigidity of the mounting brackets, we have also improved the method of attachment to the safety light curtain unit
to significantly increase the mount strength. The dead zoneless mounting bracket and the optional mounting bracket* that does not extend from aluminum frame are also available for easier use.

New high power optical system offering stable operation even for long distance setup

Increased power of emitter element

The power of the emitter has been increased significantly. The high resistance to dust and dirt contributes to the reduction of maintenance frequency.

Minimization of deviations among elements

We incorporated the element alignment technology that we cultivated for fiber sensors in the safety light curtain. This minimizes curves due to emitter and receiver mounting deviations and quality deviations due to differences in individual elements.

Redesigned emitter element layout and structure

The scattering light energy from each emitter element is guided efficiently through the lens. The light energy of the emitter element is utilized fully, and the light distribution characteristics were optimized for the specific aperture angle.*

Shuts out liquids and dust IP67, IP65 (IEC) NEMA Type 13 (NEMA 250)

The SF4D series complies with IP67 and IP65 (IEC) as well as NEMA Type 13 (NEMA 250)^*1.
The unit structure prevents the entry of not only water but also coolant and other liquids^*2 to protect the internal unit.

The SF4D series complies with the Type 13 requirements for non-explosion-proof enclosures specified in NEMA 250, "Enclosure for Electrical Equipment (1,000 V Maximum)," established by NEMA (National Electrical Manufacturers Association) in the United States.
Type 13: Enclosures for mainly indoor use which satisfy the following conditions:
・Prevention of incidental contact with the enclosed equipment
・Protection against falling dirt and protection against circulating airborne particles
・Protection against spraying, splashing and seepage of water and noncorrosive lubricants

If used in a place where cutting fluid can splash, additives in the fluid may cause degradation. Please check in advance whether the SF4D series is resistant to the specific cutting fluid used by your company.

Digital indicator with a numeric display of light incidence margin facilitates beam axis adjustment and preventive maintenance.

The light incidence margin is indicated by the “stable light incidence indicator” and “digital indicator”. This function enables appropriate beam adjustment and work quality control during installation of the device. The indicators also show whether there is dirt on the detection surface or beam misalignment due to play.
This enables the numeric display to be used for startup inspection and preventative maintenance.
* When optical synchronization is set, only the indicator on the receiver lights up.

Other features！

Well-thought-out indicators

The indicators show stable light incidence status and notify various conditions. The OSSD indicator, interlock indicator and function setting indicator are arranged between the beam axes for easy visibility.

Light incidence intensity indication

The indicator shows the light incidence margin with a numeric display (1 to 3).
The displayed number decreases when there is dirt on the detection surface or beam axis misalignment occurs due to a loose mounting condition. This provides useful information during pre-operation inspection and preventive maintenance.
* Only the indicator on the receiver lights when optical synchronization is set.

Polarity indication

The indicator shows the set polarity when power is turned on. This makes it easy to confirm proper operation after wiring.

Error indication

The new series is also equipped with the error indication function, a well-received feature of our previous models. In an environment where a PC cannot be brought in or when a problem occurs at a remote location, the displayed error number lets you identify the cause of problem. This facilitates restoration work.

Indicator for improved work efficiency

The application indicator improves work efficiency in a variety of ways by providing support to work activities ranging from daily equipment operation to installation and maintenance. The indicator function can be switched between two options.

Beam axis adjustment mode

The color of the indicator notifies whether the beam axes of both top and bottom ends are aligned properly. The indicator is easy to see from any direction so mistakes can be prevented in a long-distance setup.
When beam axes of both top and bottom ends are aligned properly:
All application indicators light blue.
When beam axis of either of top end or bottom end is aligned:
All application indicators light blue.
When beam axis of either of top end or bottom end is aligned:
The indicators of only the aligned side light red.
When beam axes of both top and bottom ends are misaligned:
All application indicators are OFF. * When optical synchronization is set, only the indicator on the receiver lights up.

Application indicator mode

Can light and blink in three colors (green, red, and orange) according to an external input. The indicator can be used to indicate work instructions or equipment status.

* When optical synchronization is set, only the indicator on the receiver lights up.
*The DIP switches in the unit must be set to use this function.
For details, see the manual.

【COLUMN】

Stable light incidence indicator that even shows the amount of margin

The stable light incidence indicator is commonly used when installing a new safety light curtain to equipment or when checking if the existing safety light curtain is operating properly. Previously, however, even if the stable light incidence indicator was ON, there was no way of knowing whether there was an ample margin or the condition is close to unstable light incidence.
The SF4D series not only shows whether the light incidence is stable or unstable but also the amount of margin with a numeric display. Therefore, it is possible to numerically manage the stability margin of the safety light curtain. When the amount of received beam intensity decreases during equipment operation due to oil mist or other reasons, the digital display shows the stability margin of the safety light curtain. Thus, cleaning can be scheduled and conducted at the most suitable timing.

Fast response time 10 ms or less

The OFF response time of the control outputs (OSSD 1, OSSD 2) of the SF4D series is 10 ms or less (when not connected in series or in parallel).
[18 ms or less when connected in series or in parallel] The SF4D series contributes to the reduction of equipment size.

Regarding the response time by number of beams, see "Control output (OSSD 1, OSSD 2) OFF response times".

Dead zoneless design enables easy calculation of safe distance.

Inherits the dead zoneless design of the previous SF4B series. Even in an L-shaped layout or a U-shaped layout, the beam pitch does not change*, making calculation of the safe distance easier.
* Excluding the finger protection type SF4D-F□(-01).

Easy to attach / detach front access cable

Uses the well-received front access cable of previous models. The cable can be attached and detached after the safety light curtain is installed on the equipment. This allows easy replacement in the event that the cable is damaged.

Series connection of up to 5 units

Up to five units (1 main sensor and 4 sub-sensors) can be connected in series, and the maximum number of beams has been increased to 256. This provides extra convenience when installing additional equipment, when increasing the detection width (protection height), and when using one system for protection of multiple locations.

Selectable synchronization method and cable to suit various applications

When choosing and installing a safety light curtain, the synchronization method and cable can be selected flexibly according to the customer's specific application and needs, such as the basic configuration or safety-enhanced configuration with improved operability.

Y-shaped connector for further reduction of wiring

When 8-core cables and line synchronization are used, connection of only five cables is required when the Y-shaped connector (optional) is used.
This allows easy connection to a safety PLC or other devices, and also helps eliminate wiring mistakes and reduce the man-hours required for wiring.

Global specifications for anywhere use in the world

The SF4D series' global specifications comply with the following standards.

*1: SF4D-□-01 only

Supports both PNP and NPN polarities

Every model in the SF4D series supports both PNP transistor output and NPN transistor output. Thus, the SF4D series products adapt to any control circuits used around the world, making it possible to use the product when PNP is installed overseas, when NPN sensors are replaced, when the positive pole is grounded in the factory, when moving equipment to overseas facilities, etc.

IO-Link Communication Unit		SFD-WL3	For use with SF4D series This unit enables the confirmation of various settings and operating status of the SF4D series from a host device using IO-Link communication. It can also save the setting information of the connected SF4D series unit.

Example of configuration

Safety output and IO-Link communication are separated from each other so that the safety light curtain can be monitored without any alteration of the safety circuit.

*1: 8-core cable for safety light curtain (optional)
*2: 4-core cable with M12 connector (commercially available product) (Note)

Note : The product and IO-Link master unit must be connected with a cable of 0.3 mm² or more. The total length of the cable must not exceed 20 m 65.517 ft.

Remote monitoring of safety light curtain status

Confirmation of light intensity margin
Incident light intensity information enables the determination of whether maintenance is necessary or not. This helps prevent shut-down of the line due to light beam deviation or dirty sensor. The information is also useful in conducting remote inspection or the like at the start of work.

Confirmation of error history
If an error occurs, the source of the error and its detail can be checked remotely, thus facilitating the identification of the problem location and analysis of the cause.

Storage of setting data, restoration of settings

One-touch setting after replacement
The setting data stored in the communication unit allows one-touch restoration of the settings when the safety light curtain is replaced.

Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 ℃ +68 ℉.
2) Except for SF4D-□-01, Korea KCs mark is acquired.
3) The operating range is the possible setting distance between the emitter and the receiver.
4) When the floating blanking function is used, the size of the minimum sensing object varies. For the detail, refer to the section on Safety distance.
5) The power supply unit must satisfy the following requirements:
  1) The power unit must be certified for use in your region.
  2) Use of the product as a unit in compliance with CE Marking: SELV (safety extra low voltage) / PELV (protected extra low voltage) power supply unit in conformity with EMC Directive and Low Voltage Directive.
  3) Use of the product as a unit in compliance with UKCA Marking: SELV (safety extra low voltage) / PELV (protected extra low voltage) power supply unit in conformity with EMC Regulations and Low Voltage Regulations.
  4) When using a commercial switching regulator, the frame ground (F.G.) terminal must be connected to ground.
  5) The power supply unit must have an output holding time of 20ms or more.
  6) If surges occur, take countermeasures such as connecting a surge absorber to the source of the surges.
  7) The power unit must be a CLASS 2 compliant unit. (When CTÜVUS mark compliance is required.)
6) In consideration of the voltage drop caused by the cable, use Control output (OSSD 1, OSSD 2) source / sink current and cable length as a guidebrline.
7) The setting can be changed when the SF4D-TM1 (optional) and Configurator Light Curtain setting software are used. Note that the setting cannot be changed when SF4D-□-01 is used.
8) For response times by number of beams, refer to the Control output (OSSD 1, OSSD 2) OFF response times.
9) Because the control output (OSSD 1, OSSD 2) must be OFF for at least 80 ms, the ON response will be delayed more than 50 ms when the light blocked time is less than 30 ms.
10) When optical synchronization is selected, if the beam axes of both the top end and bottom end are blocked, the ON response speed decreases by as much as 1 sec.
11) To use optional functions, the SF4D-TM1 (optional) and Configurator Safety Light Curtain setting software are required. Note that optional functions cannot be used when SF4D-□-01 is used.
12) Do not use or store in an environment pressurized to atmospheric pressure or higher at an altitude of 0 m.
