Banner Engineering QS18EP6DQ5 Photoelectric Sensor

The Banner Engineering QS18EP6DQ5 is a compact, diffuse‑mode photoelectric sensor in the QS18 family, designed to deliver reliable presence sensing in tight spaces and high‑speed lines. Operating from 10–30 V DC with a PNP output, it detects diffuse reflections up to 800 mm away using a 940 nm infrared emitter, and it supports both light‑on and dark‑on sensing logic for flexible integration on fast production lines. The device is IP40 rated and specified for ambient temperatures from -20 °C to +70 °C, with a fast response time around 0.6 ms and typical current draw under 100 mA, making it suitable for compact automation panels. A bright status LED provides quick troubleshooting feedback and is visible from 360°, helping operators verify sensing at a glance, while the QS18 form factor supports easy mounting and standard automation wiring. Common applications include detecting small parts on conveyors, edge detection, and general object sensing in packaging and material‑handling lines where space is limited.
