Digital Mark Sensor LX-100

Cautions For Use

  • Never use this product as a sensing device for personnel protection.
  • In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.

Mounting

  • Care must be taken regarding the sensor mounting direction with respect to the object’s direction of movement.

Do not make the sensor detect an object in this direction because it may cause unstable operation.

  • With the optional sensor mounting bracket, the tightening torque should be 0.8 N·m or less.

Sensing glossy object

  • Objects with a glossy surface have a large amount of specular reflection particles that may destabilize sensing.
    In such a case, by slightly tilting the sensor’s beam axis, this specular reflection can be reduced rendering sensing more stable.

  • If the surface of the sensing object has a shine, mount the sensor inclining approx. 10 to 15 degrees against the sensing object.

Wiring

  • Make sure to carry out wiring in the power supply off condition.
  • Take care that wrong wiring will damage the sensor.
  • 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.
  • 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.
  • 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.
  • Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.
  • Take care that short-circuit of the load or wrong wiring 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.
  • Extension up to total 100 m is possible with 0.3 mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible.

Others

  • Do not use during the initial transient time (0.5 sec.) after the power supply is switched on.
  • Take care that the sensor is not directly exposed to fluorescent light from a rapid-starter lamp or a high frequency light device or sunlight etc., as it may affect the sensing performance.
  • Do not touch the lens of the sensor by hand directly. If the lens becomes dirty, wipe it off with a soft cloth gently.
  • When the inside lens is steamed up, unscrew the lens to get rid of the condensation.
  • These sensors are only for indoor use.
  • Do not use this sensor in places having excessive vapor, dust, etc., or where it may come in direct contact with water, or corrosive gas.
  • Take care that the product does not come in contact with water, oil, grease, or organic solvents, such as, thinner, etc.
  • Make sure that stress by forcible bend or pulling with 76 N, or more, force is not applied to the sensor cable joint.
  • This sensor cannot be used in an environment containing inflammable or explosive gases.
  • Never disassemble or modify the sensor.
