Datalogic ET3-5-A5 Photoelectric Sensor Photoreflex

The Datalogic ET3-5-A5 Photoelectric Sensor Photoreflex is a reflexive, photoreflective device that detects objects by light reflected from a target. It provides dual-output compatibility with NPN and PNP configurations and operates from a 10-30 V DC supply, enabling straightforward integration with standard industrial controllers and PLC inputs. This ET3-5-A5 model belongs to Datalogic's ET3 family, offering compact sensing hardware suitable for automation tasks where a reflector is used to trigger a signal. In practical setups, it can be used for basic presence or position sensing along conveyors, at machine interfaces, or in packaging lines, where the reflectivity of the target completes the sensing loop. The 10-30 V DC range and bidirectional transistor outputs help accommodate common wiring schemes and control architectures, making it a flexible choice for engineers designing reliable, trigger-based sensing in automation projects.
