Lanbao PR18S-TM10 DC M18 Through-Beam Sensor

Lanbao PR18S-TM10 DC M18 Through-Beam Sensor

Lanbao PR18S-TM10 Series is a compact M18 cylindrical through-beam photoelectric sensor set for DC industrial automation systems. It uses separate emitter and receiver units to detect opaque objects that interrupt the beam path, giving stable long-path detection without requiring a reflector.

This PR18S version is specified for 10m non-adjustable sensing distance, 10-30V DC supply, NPN or PNP receiver output, and selectable normally-open, normally-closed, or NO+NC logic depending on part number. Available connection options include fixed 2m PVC cable models and E2 M12 4-pin connector models, with infrared 880nm LED light source, IP67 protection, and a PBT housing reference in the official specification table.

Integration Notes & Hardware Guidance

• Power selection: This is a DC photoelectric sensor series, so confirm the controller input and wiring are compatible with 10-30V DC operation.
• Beam alignment: Through-beam sensing requires correct emitter-to-receiver alignment; verify mounting distance, optical axis, and bracket rigidity during installation.
• Output selection: Match NPN or PNP receiver output to the input type of your PLC, controller, counter, or I/O module before ordering.
• Signal logic: Choose DNO normally-open, DNC normally-closed, or DNR NO+NC variants for NPN output, and DPO normally-open, DPC normally-closed, or DPR NO+NC variants for PNP output.
• Connection selection: Choose fixed cable versions for direct wiring or E2 M12 connector versions when detachable wiring and easier sensor replacement are preferred.

FAQ

What detection mode does the PR18S-TM10 Series use?

It uses through-beam detection, with an emitter and receiver mounted opposite each other. Objects are detected when they interrupt the beam path.

What sensing distance does this series support?

The official rated sensing distance reference is 10m non-adjustable.

How do I choose between NPN and PNP variants?

Select NPN or PNP according to the input type required by your PLC, controller, counter, or I/O module.

How do I choose between cable and E2 versions?

Cable versions use a fixed 2m PVC cable, while E2 versions use an M12 4-pin connector for detachable wiring and easier sensor replacement.

Does this sensor require a reflector?

No. It is a through-beam series using an emitter and receiver pair rather than a reflector.
