Handling Notes

  1. Careful attention should be made to avoid deformation of components.
  2. Environmental air must be free from corrosive gasses such as hydrogen sulfide or salt water air.
  3. Mount sensor away from direct sunlight and incandescent light.
  4. The side with emitting and receiving elements should be handled very carefully.
  5. Do not wash sensors. Liquid may get into the case and cause damage. If you must clean the surface area, use a soft cloth damped with a washing fluid such as methanol or isopropyl alcohol.
  6. Degrading LED radiant power should be addressed if sensor is used repeatedly over a long period of time.
  7. This product was designed for use in the following applications:
    • OA equipment, video equipment, consumer electronics, communication equipment, measuring equipment, and control equipment.
    • When designing a system for safety and reliability, be sure to incorporate fail-safe and other appropriate measures.
