Banner Engineering PD45VP6LLPQ Photoelectric Sensor

The Banner Engineering PD45VP6LLPQ PicoDot polarized retro laser photoelectric sensor is a compact, retroreflective laser sensor that uses a polarized red 650 nm beam for reliable detection of targets with a reflector. It operates from 10 to 30 V DC and draws less than 20 mA (exclusive of the load), with a 6-inch lead ending in a 5‑pin mini-style quick-disconnect (PQ) connector for easy integration. The device provides a complementary PNP output and features two LEDs—green to indicate power is present and amber to signal detection—with a 100 ms enable delay and an extinguishing gray wire that turns the laser off when driven high. The PD45 family is Class 2 laser certified (CDRH IEC 60825-1), and the beam at the aperture measures about 3.75 mm by 1.85 mm with a divergence of roughly 1 milliradian, suitable for precise edge- or part-detection applications. Key environmental and protection details include an IP54 enclosure rating (NEMA 4X compatibility) and built-in protection against reverse polarity, overvoltage, and transient conditions. Range is dependent on reflector and installation specifics, reflecting Banner’s guidance that retroreflective models’ reach varies with reflector type and target distance. Applications include object presence or position sensing on conveyors, packaging lines, and automated assembly where a polarized retro laser offers improved performance over non-polarized variants, with the 6-inch pigtail and PQ quick-disconnect enabling straightforward field wiring in compact control panels or enclosures.
