STS-8857 Transmissive Switch Assembly Features Non contact switching 7.6 Dimensions in mm. (-/+ 0.12) Three wires for electrical connection 3.8 Fast switching speed 14.5 Description 6.3 The STS-8857 consists of an infrared emitting diode and an NPN silicon phototransistor mounted on Optical center-line 15.5 opposite sides of a 3.8 mm wide slot. Phototransistor 3.4 3.8 switching takes place whenever an opaque object passes through the slot. The polysulfone housing (2) reduces interference from ambient light and provides 9.0 11.7 18.3 dirt and dust protection. The 40 cm minimum length 18.3 wires simplify the connection to the PC board. Absolute Maximum Ratings 3.3 Wires are omitted Wire Operating & Storage Temperature -40C to +85C for clarity Input Diode Reverse Voltage 3 V Brown Red Continuous Forward Current 50 mA Peak Forward Current (1s pulse) 3 A Power Dissipation (1) 100 mW Black Schematic Phototransistor Collector-Emitter Voltage 30 V Emitter-Collector Voltage 5 V Notes: Power Dissipation (1) 100 mW (1) Derate linearly 1.33 mW/C above 25C.
