Ssis171 – Hot

Serves as a limit switch or object detector on assembly lines to ensure parts are correctly positioned before a machine proceeds with a task.

Typically uses Infrared (IR) light to minimize interference from visible ambient light. Common Use Cases and Applications ssis171

Used in printers and photocopiers to detect paper position or to signal when a tray is empty. Serves as a limit switch or object detector

As a , it functions by emitting light and then detecting the reflection of that light off a nearby surface. If an object passes in front of the sensor, the light bounces back to a receiver, triggering an electrical signal. Technical Specifications ssis171

Reflective (The emitter and detector are housed in the same unit).
