Slotted Optical Switch OPB825, OPB825A, OPB825B, OPB825R Features:  Non-contact switching  Fast switching speed  0.160” (4.06 mm) wide slot  0.300” (7.62 mm) lead spacing  OPB825R—Optimized for ticket dispensers Description: Each OPB825, OPB825A and OPB825B have an infrared LED, while the OPB825R has a Red LED. All devices have a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of a 0.160” (4.064 mm) wide slot. OPB825 and OPB825R have no mounting tabs and is intended for direct insertion into PCBoards or dual-in-line sockets. OPB825A has one mounting tab on the phototransistor side, while OPB825B has mounting tabs on both sides (two tabs). Phototransistor switching takes place whenever an opaque object passes through the slot. Applications:  Non-contact interruptive object sensing  Assembly line automation  Machine automation  Equipment security  Machine safety Ordering Information  Ticket Sensing Part Number Description OPB825 Slotted Switch (no tabs) IR-LED OPB825A Slotted Switch (one tab) IR-LED OPB825B Slotted Switch (two tabs) IR-LED OPB825R Slotted Switch (no tabs) Red-LED Pin # Description Pin # Description 1 Anode 3 Collector 2 Cathode 4 Emitter 1 3 2 4 RoHS General Note TT Electronics | Optek Technology, Inc.
