Lanbao PR18-DM3 AC 2-Wire M18 Retro-Reflective Sensor

Lanbao PR18-DM3 AC 2-Wire M18 Retro-Reflective Sensor

Lanbao PR18-DM3-AC 2-Wire Series is an M18 cylindrical retro-reflective photoelectric sensor for AC two-wire industrial automation circuits. It provides 3m adjustable sensing distance with a reflector reference, and supports normally-open or normally-closed output depending on the selected part number.

This listing covers PR18-DM3ATO and PR18-DM3ATC AC two-wire variants, including fixed 2m PVC cable versions and E2 M12 connector versions. The series uses an infrared 880nm light source, nickel-copper alloy housing, IP67 protection, and 20-250V AC two-wire operation for reflector-based object detection.

Integration Notes & Hardware Guidance

• Power selection: This is an AC two-wire photoelectric sensor series, so confirm the input circuit supports the required two-wire AC operation before installation.
• Reflector setup: Retro-reflective detection requires correct sensor-to-reflector alignment; use a suitable reflector such as the TD-09 reference when designing the installation.
• Output selection: Choose ATO variants for normally-open output or ATC variants for normally-closed output.
• Connection selection: Choose fixed cable versions for simple wiring or E2 M12 connector versions when detachable wiring and easier sensor replacement are preferred.
• Target condition: Retro-reflective sensing can be affected by target transparency, surface finish, reflector alignment, and installation distance; test the real setup before final commissioning.

FAQ

What detection mode does the PR18-DM3-AC Series use?

It uses retro-reflective detection, so the sensor works with a reflector and detects objects when the reflected beam is interrupted.

What sensing distance does this series support?

The official rated sensing distance reference is 3m adjustable with a TD-09 reflector reference.

What is the difference between ATO and ATC variants?

ATO variants are normally-open output models, while ATC variants are normally-closed output models.

How do I choose between cable and E2 versions?

Cable versions use a fixed 2m PVC cable, while E2 versions use an M12 connector for detachable wiring and easier sensor replacement.

Is a reflector required?

Yes. Retro-reflective sensing requires a reflector aligned with the sensor; verify reflector selection and mounting before installation.
