Banner Engineering QS18VN6FF50Q5 Diffuse Laser Sensor

The Banner Engineering QS18VN6FF50Q5 is a fixed-field, 50 mm range photoelectric sensor from the World-BEAM QS18 family, designed for reliable object detection with a 10–30 V DC supply and a complementary NPN output. Housed in an 18 mm square ABS body with M18 mounting, it uses a 630 nm visible red sensing beam and fixed-field background suppression for consistent detection, with light/dark operation. The unit provides a 4‑pin connection via a 0.15 m M12 quick-disconnect cable, and carries an IP67 rating (NEMA 6) and an operating temperature range of -20 °C to 70 °C. Other key specs include max sensing distance of 50 mm, 18 mm barrel diameter, and LED indicators to show status.
