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.
  • This product has been developed / produced for industrial use only.
  • This product is suitable for indoor use only.
  • Do not use during the initial transient time(50 ms approx.)after the power supply is switched on.
  • In case of using the sensor at a place where static electricity is generated, use a metal mounting plate. Also, ensure to ground the mounting plate.
