Omron E3FB-RP21: 0.1 to 4 m with E39-R1S reflector industrial sensor, PNP output, M12 connector.
The Omron E3FB-RP21 is an E3FB M18 retro-reflective photoelectric sensor with a nominal sensing distance of 0.1 to 4 m with E39-R1S reflector. It uses PNP open-collector output and a M12 connector. The nickel-brass housing, 624 nm red LED and 0.5 ms response support industrial object detection. Light-ON or Dark-ON operation is selected by wiring; confirm reflector, target and receiver compatibility for the installation.

Engineering suggestions require suitability checks for your installation.
Detect passing objects or workpieces at a fixed point on a production conveyor.
Set the retro-reflective sensor within its rated 0.1 to 4 m with E39-R1S reflector range and match the PNP output to a compatible controller input.
Provide a photoelectric switching point for counting or presence monitoring in an automated machine.
Use the specified m12 connector and select Light-ON or Dark-ON wiring for the required logic.
