Lanbao PR18S-BC DC M18 Diffuse Photoelectric Sensor

Lanbao PR18S-BC DC M18 Diffuse Photoelectric Sensor

Lanbao PR18S-BC Series is an M18 cylindrical diffuse-reflection photoelectric sensor for DC automation systems that need compact object detection with a plastic housing. It supports 10cm non-adjustable and 40cm adjustable sensing-distance options, with NPN or PNP output and NO, NC, or NO+NC logic depending on the selected part number.

This listing covers PR18S-BC10 and PR18S-BC40 DC variants, including fixed 2m PVC cable versions and E2 M12 connector versions. The series uses an infrared LED light source, PBT housing, IP67 protection, and 10-30V DC supply for industrial sensing and control inputs.

For related Lanbao photoelectric sensors, compare the Lanbao PR18S-BC AC 2-Wire Series, Lanbao PR18-BC Metal Series, and Lanbao PR12-BC Series. For a larger cylindrical option, see the Lanbao PR30-BC Series.

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.
• Distance selection: Choose PR18S-BC10 variants for 10cm non-adjustable detection or PR18S-BC40 variants when 40cm adjustable detection is required.
• Output selection: Match NPN or PNP wiring 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, and DPO normally-open, DPC normally-closed, or DPR NO+NC variants for PNP.
• Target condition: Diffuse-reflection detection depends on target color, reflectivity, size, angle, and surface finish; test the real target before final installation.

FAQ

What detection mode does the PR18S-BC Series use?

It uses diffuse-reflection detection, meaning the emitter and receiver are in the same sensor body and the target reflects light back to the receiver.

What sensing distances are available?

This listing includes 10cm non-adjustable variants and 40cm adjustable variants.

How is PR18S-BC different from PR18-BC?

PR18S-BC uses a PBT housing, while PR18-BC is the related M18 diffuse-reflection series with a metal housing.

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.

Can it detect every object at the same distance?

No. The effective distance depends on target reflectivity, color, size, angle, and installation environment, so practical testing is recommended.
