HOA2004 Series Transmissive Optoschmitt Sensor, Transistor Output, Plastic Package.
The HOA2004 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 kOhm (nominal) pull-up resistor. The buffer logic provides a high output when the optical path is clear, and a low output when the path is interrupted. The side mounting package is useful in applications in which the interruptive element is parallel to the mounting plane. Both emitter and detector have a 0.020 in (0.508 mm) x 0.040 in (1.02 mm) vertical aperture. The narrow aperture is ideal for use in applications in which maximum position resolution is desired. The HOA2004 employs plastic molded components. For additional component information see SEP8506 and SDP8600.
Housing material is polyester. Housings are soluble in chlorinated hydrocarbons and ketones. Recommended cleaning agents are methanol and isopropanol.
