Industrial Retro-Reflex Sensor

The Wenglor LD86PA3 is a polarised retro-reflex photoelectric sensor built for industrial detection tasks. It operates on 10 to 30 V DC and connects through a 4-pin M12 plug. A stainless-steel housing with full encapsulation meets IP67, so the unit withstands wash-down and dust in factories or mobile equipment.

Suited for Conveyor and Access Control

Engineers who need a single-beam presence check up to 6000 mm with a 5° opening angle will find the range and red-light source practical. The potentiometer allows quick range adjustment on site. Buyers who require background suppression, laser precision or a teach-in button should look at other sensing principles.

Deciding Specification: 6000 mm Range

The 6000 mm sensing distance with the RQ100BA reflector is the figure that determines fit. If the application demands longer reach or a smaller beam footprint, this model will not meet the requirement.

Questions about this item

How do I verify the LD86PA3 is detecting targets correctly after wiring it to a 24 V DC supply?

Aim the red light at the RQ100BA reflector within 6000 mm; the PNP output should switch cleanly at 1 kHz with a 500 µs response time and the LED indicator will confirm operation.

What comes in the box and what must I purchase separately for the LD86PA3?

The box contains one sensor with M12 4-pin connector and potentiometer; you must buy the RQ100BA reflector or reflector foil and an M12 cable separately.

Which output version should I choose for a PLC that needs both normally-open and normally-closed signals from a single sensor?

Select the PNP NO/NC antivalent version built into the LD86PA3; it delivers both signals on the same 4-pin M12 connection without extra modules.
