Lanbao PSE-YC35 DC Background Suppression Sensor

Lanbao PSE-YC35 DC Background Suppression Sensor

Lanbao PSE-YC35 Series is a compact little-square background-suppression photoelectric sensor for DC automation systems. It is designed for 0.2-35cm adjustable sensing, helping detect the target object while reducing unwanted switching from background surfaces behind the set detection point.

This listing covers PSE-YC35DNBR, PSE-YC35DPBR, and their E3 M8 connector versions. The series uses a red 630nm light source, 5-turn distance adjustment, NPN or PNP output, NO/NC output logic, 10-30V DC supply, IP67 protection, and either a 2m PVC cable or M8 4-pin connector depending on the selected variant.

Integration Notes & Hardware Guidance

• Distance setup: Use the 5-turn knob to set the sensing distance with the real target and nearby background in place.
• Output selection: Choose DNBR variants for NPN output or DPBR variants for PNP output, matching the controller input type.
• Logic selection: Confirm NO/NC behavior through the white-wire wiring reference before final commissioning.
• Connection selection: Choose fixed 2m cable versions for direct wiring or E3 M8 connector versions when detachable wiring and easier replacement are preferred.
• Target testing: Background suppression reduces rear-object interference, but target color, reflectivity, angle, and ambient light should still be verified during setup.

FAQ

What detection mode does the PSE-YC35 Series use?

It uses background suppression, which helps reduce unwanted switching from objects behind the set detection point.

What sensing distance does this series support?

The official detection-distance reference is 0.2-35cm with 5-turn knob adjustment.

How do I choose between DNBR and DPBR variants?

Choose DNBR variants for NPN output or DPBR variants for PNP output, depending on your controller input wiring.

How do I choose between cable and E3 versions?

Cable versions use a fixed 2m PVC cable, while E3 versions use an M8 4-pin connector for detachable wiring and easier sensor replacement.

Does this sensor require a reflector?

No. PSE-YC35 uses background suppression and does not require a reflector.
