Banner Engineering QS186LE2Q5 Photoelectric Sensor

QS186LE2Q5 is Banner Engineering’s QS18 Series all‑purpose photoelectric sensor configured as a laser emitter. It uses a 650 nm visible red laser (Class 2) and, when paired with a compatible receiver in opposed‑mode sensing, delivers up to 30 m of sensing distance. The device is powered from 10–30 V DC and features a 4‑pin M12 quick‑disconnect with a 0.15 m (15 cm) cable; the Q5 suffix specifies the 150 mm PVC cable model. Housed in a rectangular ABS body with an 18 mm barrel for compact M18 mounting, it carries IP67 and NEMA 4X ratings and operates −10 to 50 C with up to 95% relative humidity at 50 C. A 10 ms power‑up delay and an LED indicator support reliable operation, and its max range and 650 nm wavelength define its laser emitter characteristics within the QS18 system.
