ACTUATOR TYPE PHOTOINTERRUPTERLead freeRoHS Standard

●Photointerrupter
A photointerrupter is an optical sensor that consists of a light-emitting part and a light-receiving part, which measure changes in light intensity caused by the interruption or reflection of light paths by an object. It can detect the presence, position, and movement of an object. Based on its optical configuration, it can be classified into ①transmissive-type photointerrupter and ②reflective-type photointerrupter. In the transmissive-type, the light-emitting part and the light-receiving part face each other, and detection is performed by blocking the light path with an object. In the reflective-type, detection is performed by receiving the changes in reflected light intensity when an object is present. There are various types, such as ③separated photointerrupter with separated light-emitting and light-receiving parts and ④actuator-type photointerrupter, which detects by blocking the light path between the light-emitting and light-receiving parts with a built-in lever.

●Actuator-type Photointerrupter
The actuator-type photointerrupter uses the optical configuration of the transmissive-type (①) and employs a built-in movable lever as an object to block the light path. It detects the interruption when some moving object presses the lever.
