Maximum compatibility with fiber sensors

The LS-500 series features the same operation, menu displays, and form factor as the FX-500 series for increased compatibility with fiber sensors.

Amplifier LS-500

Detection of beam axis misalignment
Dual outputs (self-diagnosis output)

The LS-500 series can detect any reduction in incident light intensity, for example due to the accumulation of dirt such as dust, and issue an alarm. Sensing output 2 can be set as self-diagnosis output. When you teach the threshold for sensing output 1, sensing output 2 is set accordingly, allowing you to shift the threshold by a previously set margin.


Stable sensing over the long term

The LS-500’s threshold-tracking function helps maintain stable sensing over the long term and reduce maintenance man-hours. The incident light intensity can be checked and the threshold automatically reset at a user-selected interval to track changes in light intensity due to environmental changes (such as dust, etc.) over extended periods of time.


Logic operations

The LS-500’s ability to perform three logic operations (AND, OR, and XOR) on a standalone basis eliminates the need for a dedicated controller, cuts down on wiring, and lowers costs. This functionality can also be combined with the FX-500 series.


Data bank

Eight sets of amplifier settings can be stored in the unit’s built-in memory. The ability to save and load settings reduces workload when changing the setup in a multimodel production environment.


Network communication possible

Can connect to Open Network CC-Link IE Field / CC-Link / DeviceNet / EtherCAT via Communication Unit for Open Network SC-GU3 series. Monitoring and various settings can be done from PLC, PC, etc.

Notes :

1)

Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.

2)

When using the thru-beam type LS-H101□ or LS-H102□, do not set the receiving light sensitivity (gctL) of the applicable LS-500 series amplifier to level 2 or less. This is because there is a possibility of sensing becoming unstable.

3)

The sensing range of the coaxial reflective type sensor is specified for white non-glossy paper (100 x 100 mm 3.937 x 3.937 in) as the object.

4)The sensing ranges for coaxial retroreflective type sensors are values for the RF-330 reflector. In addition, the sensing range is the possible setting range for the reflector. The sensor can detect an object less than 0.01 m 0.033 ft away. Note that if there are white papers or specular objects near the sensor head, reflected light from these objects may be received. In such cases, use the amplifier unit's receiving sensitivity function to lower the sensitivity, change the response time, or move the sensor head away from the target object. The incident light intensity may vary with the condition of the reflector surface. When using one of the applicable LS-500 series amplifiers, leave an adequate safety margin when setting the threshold.

5)Make sure to confirm detection with an actual sensor before use.

6)This product complies with the FDA regulations (FDA 21 CFR 1040.10 and 1040.11) in accordance with FDA Laser Notice No. 56, except for complying with IEC 60825-1 Ed. 3.

7)Cable cannot be extended.

Mounting

Amplifier


<How to mount the amplifier>

(1)Fit the rear part of the mounting section of the amplifier on a 35 mm 1.378 in width DIN rail.

(2)Press down the rear part of the mounting section of the unit on the 35 mm 1.378 in width DIN rail and fit the front part of the mounting section to the DIN rail.

How to mount the amplifier

<How to remove the amplifier>

 

(1)Push the amplifier forward.

(2)Lift up the front part of the amplifier to remove it.

Note:Be careful. If the front part is lifted without pushing the amplifier forward, the hook on the rear portion of the mounting section is likely to break.

 

How to remove the amplifier

<How to mount the sensor head>

(1)Insert the sensor head connector into the inlet until it clicks.

(2)Fit the cover to the connector.

 

How to mount the sensor head

Sensor head:LS-H101□

  • The tightening torque should be 0.98 N·m or less.

Sensor head LS-H101□ Mounting

Sensor head:LS-H102□

  • In case mounting this product, use a metal plate MS-EXL2-2 (accessory).
  • The tightening torque should be 0.5 N·m or less with M3 screws.

Sensor head LS-H102□ Mounting

  • In case using the dedicated sensor head mounting bracket MS-EXL2-1 (optional) when mounting this product, the metal plate MS-EXL2-2 (accessory) is required depending on the mounting direction. Mount as the diagram below indicates.

<Not requiring the metal plate>

LS-H201□, LS-H901□

  • The tightening torque should be 0.5 N・m or less.
  • When placing the sensor head horizontally or vertically, the reflector must also be positioned horizontally or vertically as shown in Fig. 1 below.
    If the sensor head is placed horizontally or vertically but the reflector is tilted as shown in Fig. 2 below, the reflection amount will decrease, which may cause unstable detection.

Wiring

  • Make sure that the power supply is off while wiring.
  • Verify that the supply voltage variation is within the rating.
  • Take care that if a voltage exceeding the rated range is applied, or if an AC power supply is directly connected, the sensor may get burnt or damaged.
  • If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
  • In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this product, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
  • Take care that short-circuit or wrong wiring of the load may burn or damage the sensor
  • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.
  • Ensure that an isolation transformer is utilized for the DC power supply. If an auto transformer is utilized, the main amplifier or power supply may be damaged.
  • Make sure to use the optional quick-connection cable for the connection of the amplifier [connector type LS-501(P)]. Extension up to total 100 m 328.084 ft is possible with 0.3 mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible. Set the supply voltage after considering the voltage drop caused by the cable’s resistance. When adding units, wiring length must not exceed 50 m 164.042 ft (for 5 to 8 amplifiers) or 20 m 65.617 ft (for 9 to 16 amplifiers).

Others

  • Do not use during the initial transient time (0.5 sec. approx.) after the power supply is switched on.
  • Because the sensitivity is higher in U-LG and HYPER modes than in other modes, it can be more easily affected by extraneous noise. Check the operating environment before use.
  • This sensor is suitable for indoor use only.
  • Avoid dust, dirt, and steam.
  • Take care that the product does not come in direct contact with water, oil, grease, or organic solvents, such as, thinner, etc.
  • This sensor cannot be used in an environment containing inflammable or explosive gasses.
  • Never disassemble or modify the sensor.
