Description:
Each OPB825, OPB825A and OPB825B consists of an infrared emitting diode and 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 has 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).

Features:
• Non-contact switching
