OPB830 and OPB840 Series Slotted Optical Switches
This family of slotted optical sensors, from Optek Technology, enable you to create a custom device from a standard product line. This flexibility includes choices of aperture, shell material, and lead spacing. An opaque plastic housing minimises the sensitivity to visible and near IR light.
The parallel faces inside the slot are covered with an IR transmissive plastic or opaque plastic with an opening. The IR transmissive plastic is suitable for applications which require dust protection and the opaque is for applications that require maximum protection against ambient light.
