HOA7720/7730 Series
Connectorized Transmissive Optoschmitt Sensor
DESCRIPTION The HOA7720/7730 Series 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 and Schmitt trigger with either of two output configurations:
Totem pole (HOA7720-M11) Open collector (HOA7730-M11)
The totem pole output is well-suited for 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 in...
