H22A1 Slotted Opto Isolator Module (Encoder Sensor)

H22A1 Slotted Opto Isolator Module (Encoder Sensor)

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