H22A1 Slotted Opto Isolator Module (Encoder Sensor)

H22A1 Slotted Opto Isolator Module (Encoder Sensor)

The H22A1 Slotted Opto Isolator Module is a single-channel photo interrupt switch. It integrates an infrared emitting diode (IR LED) and an NPN silicon phototransistor. The module's polycarbonate housing establishes a precise optical path. This configuration enables the detection of object presence or absence. Interruption of the infrared beam by an object, such as an encoder disc, alters the phototransistor's output logic level. This mechanism facilitates position feedback and object sensing. The design prioritizes mechanical resolution, coupling efficiency, and ambient light rejection. It provides a component for electronic applications requiring optical switching and sensing.
