Integration Notes & Hardware Guidance

• Reflector alignment: Mount the sensor and reflector face-to-face, then verify stable signal return across the required detection distance.
• Output selection: Choose PSS-PM3DNBR-E2 for NPN output or PSS-PM3DPBR-E2 for PNP output, matching the controller input type.
• Connector planning: Use the E2 version when an M12 connector is preferred for detachable field wiring and faster replacement.
• Distance setup: Use the single-turn potentiometer to tune the sensing margin after the reflector position is fixed.
• Environment check: Reflector cleanliness, target surface, ambient light, vibration, water spray, and mounting angle should be verified on the final machine.

FAQ

What is the difference between PSS-PM and PSS-PM-E2?

PSS-PM is the cable version reference, while PSS-PM-E2 uses an M12 connector for detachable wiring.

What sensing mode does the PSS-PM-E2 Series use?

It uses polarized retro-reflective sensing, so the sensor works with a reflector across the detection path.

What is the rated sensing distance?

The PSS-PM3-E2 reference sensing distance is 3m when the sensor and reflector are correctly aligned.

How do I choose between PSS-PM3DNBR-E2 and PSS-PM3DPBR-E2?

Choose PSS-PM3DNBR-E2 for NPN output or PSS-PM3DPBR-E2 for PNP output, depending on your controller input wiring.

Does this sensor need a reflector?

Yes. Polarized retro-reflective sensing requires a reflector for stable detection.
