The indicator of the safety switch on the closed door flashes to notify the unsafe condition.
Two Types to Choose from
For doors with aluminum frames
Visible type
For doors without aluminum frames
Compact type
Flashing Function Notifies Unsafe Condition
When a door is intentionally kept open, the indicator of the safety switch on that door changes to red and the indicators of the safety switches on all other doors flash in green.
The operator can recognize immediately the equipment status and which door is open.
BEFORE Conventional system
When one of the doors was kept open, the indicators of all other interlocked safety switches turned off so there was no way of knowing which door was open without checking each door.
When the safety switch was installed on the inner side of the door, the indicator of the safety switch was not visible from the outside of the equipment area in some cases.
[Industry’s First*] AFTER SG-P series
* As of September 2020, in-company survey
The indicator of the safety switch on the open door changes to red and the indicators on all other doors flash in green.
The operator can recognize immediately the equipment status and which door is open.
The visible type actuator allows the light from the switch body to pass through so that the indicator light is visible from the actuator side.
This ensures high visibility of the safety switches installed on doors with aluminum frames.
* Industry’s first safety door switches with this function as of October 2020, in-company survey.
Master-Slave (Standard / Sub) System for Reduced Wiring
Serial Connection of Up to 30 Units without Dedicated Controller
The SG-P series standard units, which are used as master units, can output safety signals all at once (OSSD1 / OSSD2).
The sub units used as slave units minimize the wiring for a cascade connection.
There is no need to purchase a dedicated controller. The presently used safety controller / circuit can be connected directly. Up to 30 units can be connected, thus contributing to wire-saving.
No Cumbersome Manual Pairing Necessary before Installation
* High-code models (SG-P20□-M-□, SG-P20□-S) only
During the initial setting, bring the switch body close to the actuator and turn on the power to let the safety switch detect the actuator for 3 seconds. This simple procedure completes the pairing. In a cascade connection, pairing can be achieved all at once by simply turning on the power. This reduces the man-hours required for starting up the equipment.
* Low-code models (SG-P10□-M-□, SG-P10□-S) do not require pairing.
Helps Prevent Intentional Deactivation of Safety Function
The ISO 14119:2013* international standard stipulates a design requirement that deactivations of safety functions shall be minimized.
Export of equipment sometimes requires to meet this standard. The SG-P series products are available with two different coding levels: High-code models and Low-code models. The High-code models are compatible with ISO 14119:2013* coding level (high level coded actuators) and prevent intentional deactivation of their safety function.

Maintenance Actuator (sold separately) for Facilitating Maintenance Work
Designed for one-touch installation, the maintenance actuator generates a signal to switch the control mode.
The maintenance actuator mounts on the SG-P series and generates a signal to switch the control mode. This signal can be used as a trigger to restrict machine operation. Two types of maintenance actuator are available: overall maintenance type (SG-PK-M1) and individual maintenance type (SG-PK-M2).
One-touch installation
Indicating the name of the department that owns the maintenance actuator and the name of person in charge on a commercially available key tag and attaching it to each unit makes it easy to manage the users.
* Individual maintenance type actuator (SG-PK-M2) is mounted on a compact type unit in the above example.
[Overall maintenance type (SG-PK-M1)]
The source of hazard in a hazardous area can be accessed from any door. OSSD1 maintains ON status regardless of which door is opened.
* Be sure to evaluate the control output correctly.
* Can be used only with the standard switch body.
* All switch bodies in series connection change to the maintenance mode.
* The indicators on the switch bodies in series connection change in color.
* All doors with the switch bodies in series connection can be opened and closed. Take care not to allow unauthorized persons to open or close the doors.
[Individual maintenance type (SG-PK-M2)]
The source of hazard in a hazardous area can be accessed from the specified door. When any other door is opened, OSSD2 also turns OFF.
* Be sure to evaluate the control output correctly.
* Can be used with the standard or sub switch body.
* Can be installed to multiple switch bodies for simultaneous use.
* Only the switch bodies installed with this product type can be individually changed to the maintenance mode.
* The indicators on the switch bodies in series connection change in color.
Large and Bright Indicator for the Notification of Maintenance Mode Status to Workers
When the SG-P unit is mounted with the maintenance actuator, the large indicator lights in "yellow".
The workers can readily recognize that the equipment is in maintenance.
* Compact type unit is shown above as an example.

About maintenance actuators (optional)
By directly mounting the maintenance actuator to the switch body while the door is open, it is possible to distinguish accidental opening of the door. Two types of maintenance actuators are available: overall maintenance type (SG-PK-M1) and individual maintenance type (SG-PK-M2 (Note)).
Note: In the case of the individual maintenance type SG-PK-M2, multiple units can be installed and used simultaneously.
| Type | Overall maintenance type | Individual maintenance type |
|---|---|---|
| Model No. | SG-PK-M1 | SG-PK-M2 |
| Ambient temperature | 0 to +40 ℃ 0 to +104 ℉ (No dew condensation), Storage: -25 to +65 ℃ -13 to +149 ℉ | |
| Ambient humidity | 35 to 85 % RH, storage: 35 to 85 % RH | |
| Vibration resistance | 10 to 55Hz, 1 mm double amplitude, 2 hours each in X, Y, and Z directions | |
| Shock resistance | 300 m/s2 (30 G approx.), 3 times each in X, Y, and Z direction | |
| Material | POM (polyacetal) | |
| Weight | 7 g approx. | |
・Overall maintenance type (SG-PK-M1) can be used only on standard switch bodies.
・Individual maintenance type (SG-PK-M2) can be used on standard and sub switch bodies.
・When maintenance actuators are used, redundant input monitoring (dual channel monitoring) of OSSD1and OSSD2 for the SG-P series by a safety controller, etc. cannot be used.
・When using a maintenance actuator, be careful that the normal actuator will not be detected at the same time.
・Determine whether to use the normal mode or maintenance mode according to the system.

Operation differs between the overall maintenance type (SG‑PK‑M1) and individual maintenance type (SG‑PK‑M2). The output operation and indicator operation of the switch body when used with each maintenance actuator is as follows
When using overall maintenance type actuator (SG-PK-M1)
The SG-PK-M1 can only be used on standard switch bodies.
Note:Individual maintenance type (SG-PK-M2) cannot be used when overall maintenance type is used.
