The E3S-R2E4: The infrared LED source and 1 ms response time suit it for object detection on conveyors or packaging lines where a reflector is mounted opposite the sensor. Metal housing and IP67 rating mean it holds up in wash-down or dusty environments; the 2 m cable with NO/NC switching output gives flexibility in wiring.
