Description
HOA7720/7730 Connectorized Transmissive Optoschmitt Sensor .
The HOA7720/7730 Series consists of an infrared emitting diode facing an Optoschmitt detector encased in a black thermoplastic housing.
Features
* Direct TTL interface
* No interface circuits required
* Inverting logic
* Two device output options
* High resolution
Applications
* which require fast transition times. The open collector allows the output of the sensor to interface with circuit elements driven by supply voltages other than Vcc supply. The inverting logic provides a high output when the optical path is interrupted, and a low output when the path is clear. The in
