Cautions For Use

This website is a guide to select a suitable product.
Be sure to read the instruction manual attached to the product prior to its 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 regulations and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.

Cautions for laser beams

  • These products are Class 1 laser in compliance with IEC, JIS standards and FDA* regulations. To reduce the risk of danger, do not look directly at the laser beam or view it through an optical system.
  • A label with instructions as found at the below is affixed to the product. Handle this sensor as per the instruction on the labels.
*This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 50, dated June 24, 2007, issued by CDRH (Center for Devices and Radiological Health) under the FDA (Food and Drug Administration).
  • The safety standard IEC 60825-1-2007 specifies the use of laser beam products. Please read it carefully before using the laser beam sensor.

Safety standards for laser beam products

  • A laser beam can harm human being’s eyes, skin, etc., because of its high energy density. IEC has classified laser products according to the degree of hazard and the stipulated safety requirements. LS-H□ is classified as Class 1 laser.
Classification by IEC 60825-1
Classification Description
Class 1 Lasers that are safe under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing.

Safe use of laser products

  • For the purpose of preventing users from suffering njuries by laser products, IEC 60825-1 (Safety of laser products). Please check the standards before use.

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.

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.
