Industrial QM26VPAF400Q5 Photoelectric Sensor

Banner Engineering QM26VPAF400Q5 is a 400 mm‑range diffuse‑mode photoelectric sensor from the QM26 washdown family, featuring adjustable background suppression to reliably detect objects on cluttered or reflective surfaces. It uses a 620 nm red light beam and comes in a rectangular stainless‑steel grey housing (15.3 x 14 x 32.6 mm) with an acrylic/PMMA lens, designed for rugged environments and easy cleaning. The unit operates on 10–30 V DC with less than 10% ripple and provides a complementary PNP solid‑state output rated up to 100 mA, with built‑in short‑circuit and reverse polarity protection. A fast response time is specified (typical < 0.5 ms) with a maximum switching frequency of 2 kHz and a readiness delay of ≤ 300 ms, suitable for high‑speed conveyor or packaging lines. Wiring options include a 200 mm PVC pigtail or an M12 Euro QD connector (4‑pin), giving flexible installation on a variety of machines. As part of Banner’s QM26 washdown line, the QM26VPAF400Q5 supports background suppression adjustments to help distinguish targets from backgrounds in wet or sanitary environments, making it a common choice for part presence, position sensing, and line‑side verification in manufacturing settings.
