TT Electronics Optoswitch, Phototransistor; Sensor Output Tt Electronics/optek Technology OPB840W51Z

The Transmissive Photo Interrupter, part number 61M8108, is a phototransistor-based optical switch designed for non-contact object sensing applications. It features a 0.125-inch (3.18 mm) wide slot and is available in two configurations: the L Series with PC board mount lead spacing and the W Series with 24-inch (610 mm) 26 AWG wire leads. The device operates with a forward DC current of up to 50 mA and has a forward voltage of 1.7 V. It can withstand a collector-emitter voltage of 30 V and an emitter-collector voltage of 5 V, with a maximum power dissipation of 100 mW for both input and output components. The operating temperature range for the L Series is -40°C to +85°C, while the W Series operates from -40°C to +80°C. The housing is made from opaque plastic to minimize sensitivity to ambient light, and it is RoHS compliant. This product is suitable for applications in assembly line automation, machine safety, and equipment security.
