Overview

Banner’s Q20 family of sensors offers a full complement of

sensing modes, with the excellent performance expected of much

larger sensors. Their compact plastic housings feature

overmolded construction for superior robustness and sealing.

Their popular rectangular design is easy to mount into tight

spaces; integral threaded mounting holes eliminate the need for

separate mounting nuts.

The single-turn Gain potentiometer on most models and bright

LEDs (positioned on top of the housing for 360° visibility) provide

easy alignment and configuration for reliable sensing.
