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 laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
  • This product is classified as a Class 1 Laser Product in IEC / JIS standards and a Class I Laser Product in FDA regulations 21 CFR 1040.10. Do not look at the laser beam through optical system such as a lens.
  • The following label is enclosed with this product. Handle the product according to the instruction given on the warning label.

Class 1 type

pic01   (The English warning label based on FDA regulations is pasted on the FDA regulations conforming type.)

Mounting

  • The emitter and the receiver must face each other with proper slit orientation so that the beam can be received.
  • The tightening torque should be 1.17 N・m or less. When mounting the sensor with the attached sensor mounting bracket, the sensor must be fixed on both sides.

Mounting

Wiring

Do not use a power supply having a single-winding transformer (auto-transformer) as this can be dangerous.

  • In LA-510 and LA-511, capacitor earth is used to enhance the noise characteristics. In case there is a high frequency noise generating equipment, such as, an ultrasonic welding machine, etc., near the sensor head and if the mounting base is electrically conducting (metallic, etc.), then insulate the sensor head from the mounting base.

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 equirements. LA-510 is identified as a “Class 1” laser product.

Classification by IEC 60825-1

ClassificationDescription
Class 1Lasers that are safe under reasonably foreseeable conditions of operation, including the use of optical instruments for intrabeam viewing.
Class 1MLasers emitting in the wavelength range from 302.5 nm to 4,000 nm which are safe under reasonably foreseeable conditions of operation, but may be hazardous if the user employs optics within the beam.
Class 2Lasers that emit visible radiation in the wavelength range from 400 nm to 700 nm where eye protection is normally afforded by aversion responses, including the blink reflex. This reaction may be expected to provide adequate protection under reasonably foreseeable conditions of operation including the use of optical instruments for intrabeam viewing
Class 2MLasers that emit visible radiation in the wavelength range from 400 nm to 700 nm where eye protection is normally afforded by aversion responses, including the blink reflex. However, viewing of the output may be more hazardous if the user employs optics within the beam.
Class 3RLasers that emit in the wavelength range from 302.5 nm to 106 nm where direct intrabeam viewing is potentially hazardous but the risk is lower than for Class 3B lasers, and fewer manufacturing requirements and control measures for the user apply than for Class 3B lasers
Class 3BLasers that are normally hazardous when direct intrabeam exposure occurs (i.e. within the NOHD). Viewing diffuse reflections is normally safe.
Class 4Lasers that are also capable of producing hazardous diffuse reflections. They may cause skin injuries and could also constitute a fire hazard.

Safe use of laser products

  • For the purpose of preventing users from suffering injuries by laser products, IEC 60825-1 (Safety of laser products). Please check the standards before use. (Refer to information about laser beam.)

Others

  • The sensor's output is proportional to the amount of laser beam received. Since there is some variation in the light intensity at the center and the periphery of the sensing area, take care that “output = dimension” may not hold.
  • For stable operation, use the sensor 10 min., or more, after switching on the power supply.
