Omron E3ZG-R61-S 2M is an NPN retro-reflective sensor with 4 m range using E39-R1S, 2 m cable, MSR and IP65 protection.
The Omron E3ZG-R61-S 2M is a pre-wired retro-reflective photoelectric sensor with mirror surface rejection (MSR) and NPN output. Its sensing distance is up to 4 m with the separately ordered E39-R1S reflector, or 3 m with E39-R1; the minimum sensor-to-reflector spacing is 100 mm. The sensor uses a 660 nm red LED, 2 m cable, 12–24 VDC supply and 1 ms response, with IEC IP65 protection. Omron’s datasheet confirms the model specifications; current supply status is unconfirmed.

Engineering suggestions require suitability checks for your installation.
A conveyor may need a sensor signal when a package interrupts a fixed optical path.
The R61-S can be paired with an E39-R1S reflector for up to 4 m rated range; mount the reflector at the specified spacing and confirm the target does not create unwanted reflections.
A packaging line may need to detect cases crossing a defined point while rejecting reflected light from the reflector.
MSR operation helps distinguish the reflector return; validate performance for transparent or highly reflective packaging and install the required reflector separately.
