Banner Engineering QS18VN6R Photoelectric Sensor

The Banner Engineering QS18VN6R World-BEAM QS18 Series All-Purpose Photoelectric Sensor is the receiver element of a through-beam sensing pair in Banner's compact QS18 family, engineered for reliable non-contact detection in harsh industrial environments. It runs from 10 to 30 V DC and provides a complementary solid-state NPN output, with a 2 m PVC cable for straightforward installation. The unit offers up to 20 m sensing range and an IP67-rated enclosure, capable of withstanding dust, water exposure, and temperatures from -20 to +70 C. Green LED indicates power, while yellow LEDs show the switching state, with indicators visible from 360 degrees to aid alignment and troubleshooting. Model 61621 identifies this specific unit, and it is commonly used with Banner QS18 emitters to form a simple through-beam configuration in industrial automation tasks where fast response and dependable detection are important.
