●OPB859/860/870/880/890 Series Slotted Optical Switches

●This family of slotted optical sensors, from Optek Technology, enable the use to create a customer device from a standard product line. This flexibility includes choices of slot width, aperture, shell material, mounting configurations and lead spacing or wires. An opaque plastic housing minimizes the sensitivity to visible and near IR light. The parallel faced 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. The OPB859, OPB860, OPB870, OPB880 and OPB890 utilize a phototransistor sensor. Suitable applications for the slotted optical switches include; non-contact object sensing, assembly line automation, machine automation, equipment safety and machine safety.
