OPB800W Wide Gap Slotted Optical Switches

Optek / TT Electronics OPB800W Wide Gap Slotted Optical Switches are high-flexibility, transmissive photointerrupters featuring a 0.375" (9.525mm) wide slot that integrates an infrared LED emitter and a silicon phototransistor detector. These optical switches are designed for remote mounting, providing 24" (610mm) 26AWG UL-insulated wire interconnects for versatile installation. The switches enable non-contact detection of motion, position, or object interruption with improved mechanical alignment tolerance compared to standard narrow-slot interrupters.
