Wenglor LD86PCV3 Retroreflective Sensor Needs to Be Used in Conjunction with a

LD86PCV3 is a universal M18 stainless steel retro-reflective photoelectric sensor manufactured by Wenglor. It adopts polarized red light and dual-lens optical system, requiring a matching reflector (Model RQ100BA) for operation. Designed for long-distance object presence detection in general industrial automation, it effectively eliminates false triggers caused by glossy, mirror-like metal surfaces via built-in polarization filter, delivering stable detection performance across diverse workshop conditions.

1. Polarized red light avoids false detection of glossy objects
   Integrated polarization filter blocks mirror reflection from stainless steel, aluminum sheets and polished plastic, ensuring reliable detection without blind spots for shiny workpieces.
2. 6-meter ultra-long sensing distance with compact M18 housing
   Single sensor covers up to 6 m measurement range, replacing multiple short-range sensors for long conveyor, warehouse and logistics equipment, reducing hardware and wiring costs.
3. Robust stainless steel housing for harsh industrial environments
   V2A stainless steel body resists mechanical impact, cutting fluid, oil mist and corrosion, far more durable than plastic sensors for metal machining, stamping and heavy-duty production lines. IP67 full encapsulation withstands splashing water and workshop dust.
4. Dual-lens optical system for stable signal output
   Separated transmit and receive lenses minimize light crosstalk, delivering consistent switching signals even under uneven ambient light or slight reflector offset.
5. Flexible on-site adjustment & standard industrial interface
   Built-in potentiometer enables quick on-site fine-tuning of detection distance; rotatable M12 4-pin connector supports flexible cable routing. PNP output is fully compatible with all mainstream PLC, relay and automation control systems.
6. High-speed switching & long service life, low maintenance
   1 kHz high switching frequency adapts to high-speed conveyor counting and object detection. 100,000-hour LED lifespan and complete circuit protection greatly reduce failure rate and replacement frequency for 24/7 continuous operation.
