Handling Notes
- Careful attention should be made to avoid deformation of components.
- Environmental air must be free from corrosive gasses such as hydrogen sulfide or salt water air.
- Mount sensor away from direct sunlight and incandescent light.
- The side with emitting and receiving elements should be handled very carefully.
- 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.
- Degrading LED radiant power should be addressed if sensor is used repeatedly over a long period of time.
- 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.
