Functions and Operating Principle

The sensor operates on the through-beam principle – a light beam is transmitted from the emitter to the receiver module.
When an object passes between them and interrupts the light path, the receiver detects the interruption and outputs a signal.
This operation ensures very high detection accuracy and low false trigger probability, making it suitable even for small or fast-moving objects.

Use and Application

For home users or hobbyists: Suitable for object detection in workshops or individual automation projects.
For engineers / automation specialists: Used in robotics, production lines, conveyors, counting or positioning systems.
For electricians / technicians: Easy installation due to compact housing; clear LED indicators help quickly determine the operating state and detect faults.

Pros

Compact size – suitable for confined spaces

Accurate and fast response

High resistance to ambient light and interference

Dust and moisture resistant

Visible red beam – easy alignment

Cons

Requires precise alignment of emitter and receiver

Cannot detect transparent or light-transmitting objects
