Banner Engineering T18SN6DQ Photoelectric Switch

The Banner Engineering T18SN6DQ is a diffuse-mode photoelectric switch that detects the presence of objects by reflected light in a DC, continuous-operation configuration. It operates on 10–30 VDC and provides an NPN output, with a quick-disconnect (QD) connection for straightforward wiring. In diffuse operation, the sensor relies on light reflected from the target, with a practical sensing range up to 500 mm depending on target reflectivity and surface texture. This model is well-suited for short-range presence detection on conveyors, in packaging lines, and in chute or hopper applications where compact, self-contained sensing is advantageous. Key verified specs include 10–30 VDC supply, current draw around 150 mA, NPN output, diffuse sensing mode, and QD connection on the T18SN6DQ.
