💡 How does a retroreflective photoelectric sensor work in industrial automation? This handy device uses a reflector to bounce infrared light between the emitter and receiver, allowing fast, non-contact detection of moving objects.
- The beam is interrupted by a target, triggering the relay to switch AC loads
- It works with a DC supply in the 12-24 V range and provides a clean digital output
- It is easy to mount on walls or brackets for quick setup in lines and gates
- Suitable for security and automation tasks without touching the moving parts
