It consists of a GaAs LED and a silicon photo-transistor packaged into an injection molded housing and facing each other across a 0.315" (8.0 mm) gap. The housing is featuring locating knobs for accurate mounting. FEATURES * No contact switching * 8mm wide slot * 0.5 mm aperture width * Opaque black plastic housing * Locating knobs on housing base for accurate mounting * Transistor Output (c) 2003 Fairchild Semiconductor Corporation Page 1 of 5 4/14/03 PHOTOTRANSISTOR OPTICAL INTERRUPTER SWITCH QVE00034 ABSOLUTE MAXIMUM RATINGS (TA = 25C unless otherwise specified) Parameter Operating Temperature Storage Temperature Soldering Temperature Soldering Temperature EMITTER Continuous Forward Current Reverse Voltage Power Dissipation(1) IF VR PD VCEO VECO IC PD 50 6 100 mA V mW (Iron)(2,3,4) (Flow)(2,3) Symbol TOPR TSTG TSOL-I TSOL-F Rating -55 to +100 -55 to +100 240 for 5 sec 260 for 10 sec Units C C C C SENSOR Collector-Emitter Voltage Emitter-Collector Voltage Collector Current Power Dissipation(1) 30 4.5 20 150 V V mA mW NOTES 1.
