Transmissive Optical Sensor with Phototransistor

Output

Description

These devices have a compact construction where the

emitting-light sources and the detectors are located

face-to-face on the same optical axis. The operating

wavelength is 950 nm.

The detector consists of a phototransistor. Due to the

special construction, the depth of the gap is equal to

a package height of 4 mm.

Applications

D Position sensor for shaft encoder,

D Detection of opaque 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 Gap 2.8 mm

D Package height: TCST5123: 4.0 mm

D Plastic polycarbonate housing

D Subminiature construction

D Snap-in mounting mechanisms

D Current Transfer Ratio (CTR) of typical 20%
