HOA7730-M11

Overview

HOA7720/7730 Series Connectorized Transmissive Optoschmitt Sensor, Transistor Output, Plastic Package.

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 interrupted, and a low output when the path is clear.

The infrared emitting diode is biased internally, eliminating the need for any external circuitry. Interconnection is simplified through the use of the integral Tyco three-pin connector.

Both the emitter and detector have a 0.508 mm x 1,78 mm [0.020 in x 0,070 in] vertical aperture. The narrow aperture is ideal for use in applications in which the maximum rejection of ambient light is important, and the maximum position resolution is desired.

The HOA7220/7330 series employ plastic molded components. Housing material is opaque polycarbonate. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
