Leuze ET5B/4 – Energetic Diffuse Photoelectric Sensor, Series 5B

The Leuze ET5B/4 is an energetic diffuse photoelectric sensor from the compact Series 5B designed for reliable object detection without requiring a reflector. It operates using the diffuse reflection principle, detecting objects by measuring the light reflected back from the target surface. The integrated Teach function allows quick sensitivity adjustment, making the sensor suitable for objects with different colours and surface finishes.
