Reflective Optical Sensor with Transistor Output TCRT5000(L) Vishay Telefunken Description The TCRT5000(L) has a compact construction where the emitting-light source and the detector are arranged in the same direction to sense the presence of an ob- ject by using the reflective IR beam from the object. The operating wavelength is 950 mm. The detector consists of a phototransistor. Applications D Position sensor for shaft encoder D Detection of reflective material such as paper, IBM cards, magnetic tapes etc. D Limit switch for mechanical motions in VCR D General purpose – wherever the space is limited Features D Snap-in construction for PCB mounting D Package height: 7 mm D Plastic polycarbonate housing construction which prevents crosstalk D L = long leads D Current Transfer Ratio (CTR) of typical 10% 94 9442 15116 A C C E Top view Order Instruction Ordering Code TCRT5000 TCRT5000(L) Sensing Distance 12 mm 12 mm Remarks Leads (3.5 mm) Long leads (15 mm) Document Number 83760 Rev.
