HOA2003
Transmissive Optoschmitt Sensor
FEATURES • Direct TTL interface • Buffer logic • 0.010 in.(2.54 mm) offset detector leads • 0.125 in.(3.18 mm) slot width • Accurate position sensing • Dust protective housing
DESCRIPTION The HOA2003 consists of an infrared emitting diode facing an Optoschmitt detector encased in a black thermoplastic housing. The photodetector consists of a photodiode, amplifier, voltage regulator, Schmitt trigger and an NPN output transistor with 10 kì (nominal) pullup resistor. The buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted.
