Banner Engineering QS18VP6LDQ6 Laser Diffuse Sensor

The Banner QS18VP6LDQ is a World‑BEAM QS18 laser‑diffuse sensor that detects diffuse reflections up to 300 mm using a 650 nm visible red laser. It runs on 10–30 V DC and delivers a single PNP solid‑state output through a 4‑pin M8 quick‑disconnect with a 0.15 m cable. Housed in a compact ABS rectangular body with an 18 mm barrel and M18 mounting compatibility, it carries IP67 protection and NEMA 4X compliance for rugged industrial environments. The sensor operates as a Class 1 laser device with a small visible spot and features a potentiometer for adjustments and LED indicators for status. Key timings include a 200 ms power‑up delay, a 0.7 ms output response time, and 130 µs repeatability; the sensing beam is 650 nm and the lens is acrylic. It supports Light/Dark operation in diffuse mode, accepts a wide operating temperature from −10 °C to 50 °C and is rated for 95% relative humidity at 50 °C. This variant is available with a 150 mm (6 in) cable for quick panel or bracket mounting, making it well suited for compact part‑detection tasks on automation lines where fast, reliable presence sensing is required.
