Banner Engineering QS18VN6LPQ-73056 Photoelectric Sensor

Banner Engineering QS18VN6LPQ-73056 is a World‑Beam QS18 series photoelectric sensor engineered for polarized retroreflective detection, using a 630 nm visible red light to reliably sense reflectors up to 3.5 m (12 ft) away. It operates from a 10–30 VDC supply and provides an NPN (sinking) output, with a DC rated current up to 100 mA, making it compatible with common controller inputs. The sensor features a bright status LED visible from 360°, a potentiometer for setting adjustments, and a fast typical response time under 0.6 ms with a switching frequency up to 800 Hz, plus a readiness delay not exceeding 100 ms and residual ripple under 10%. Its compact QS18 housing is made of ABS plastic with a rectangular form factor and a plastic/acrylic lens, designed for straightforward mounting in tight spaces. This model is well suited for applications on conveyors, packaging lines, and automated assemblies where a polarized retroreflective setup provides reliable detection of reflective targets while minimizing false positives from ambient light.
