The HOA2005-001 is a panel/chassis-mount Transmissive Photo Interrupter with phototransistor output. It 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 10kR 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 blocked. It is ideal for use in applications in which maximum position resolution is desired. It employs a built-in strain relief for maximum wire attachment strength. This arrangement provides excellent protection against ambient light while eliminating aperture openings which could be clogged by airborne contaminants. The HOA2005 series employs plastic molded components.
