Lanbao PR18-BC AC 2-Wire M18 Diffuse Photoelectric Sensor

Lanbao PR18-BC AC 2-Wire M18 Diffuse Photoelectric Sensor

Lanbao PR18-BC-AC 2-Wire Series is an M18 cylindrical diffuse-reflection photoelectric sensor for AC control systems that need simple two-wire object detection. It supports 10cm non-adjustable and 40cm adjustable sensing-distance options, with NO or NC output logic depending on the selected part number.

This listing covers PR18-BC10ATO, PR18-BC10ATC, PR18-BC40ATO, and PR18-BC40ATC variants, plus matching E2 M12 connector versions. The series uses an infrared LED light source, nickel-copper alloy housing, IP67 protection, and either 2m PVC cable or M12 connector wiring.

For related Lanbao photoelectric sensors, compare the Lanbao PR18-BC DC Series, Lanbao PR12-BC Series, and Lanbao PR30-BC Series. For a square diffuse-reflection option, see the Lanbao PTL-BC80S-D Series.

Integration Notes & Hardware Guidance

• Power selection: This is an AC two-wire sensor series, so confirm the controller input and load are compatible with 20-250V AC operation.
• Distance selection: Choose PR18-BC10 variants for 10cm non-adjustable detection or PR18-BC40 variants when 40cm adjustable detection is required.
• Output logic: Choose ATO variants for normally-open switching or ATC variants for normally-closed switching.
• Target condition: Diffuse-reflection detection depends on target color, reflectivity, size, angle, and surface finish; test the real target before final installation.
• Connection choice: Select fixed 2m PVC cable versions for direct wiring or E2 M12 connector versions when detachable wiring and easier replacement are preferred.

FAQ

What detection mode does this PR18-BC-AC sensor 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 do I choose between ATO and ATC variants?

ATO variants are normally open, while ATC variants are normally closed. Choose the output logic required by your control circuit.

What is the difference 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.
