Banner Engineering QS18VP6LPQ8 Photoelectric Sensor

The Banner Engineering QS18VP6LPQ8 is a polarized retroreflective, all‑purpose photoelectric sensor in the compact QS18 format, engineered for fast, reliable detection of objects on conveyors, packaging lines, and assembly equipment. It features an 18 mm rectangular housing with an ABS body and a plastic acrylic lens, configured for 10–30 V DC operation with protection against short circuits and reverse polarity. The device provides a PNP output that can be wired as normally open or normally closed, and it supports polarized retroreflective sensing with adjustable background suppression for challenging backgrounds, plus an adjustable setting (potentiometer) for fine‑tuning sensitivity. In terms of sensing performance, the QS18VP6LPQ8 offers a broad range suitable for many applications, typically covering from 50 mm up to 3,500 mm, and it emphasizes fast switching with a typical response time under 0.6 ms and a readiness delay of up to about 100 ms. The combination of a compact 18 mm form factor, reliable solid‑state output, and straightforward sensitivity adjustment makes it well suited for tight spaces on automation lines where clear‑object detection and consistent performance on reflective or varying surfaces are required.
