The Banner QS18E sensor is a high performance photoelectric sensor
with IO-link and configurable multifunction input/output. For opposed-
mode models, the receiver has a configurable multifunction input/output
and the emitter has a configurable multifunction input.

1.3 Opposed-Mode Models: Noise and Crosstalk Immunity
Optical synchronization between the emitter and receiver provides ambient light immunity and crosstalk avoidance not
typically available in opposed-mode sensing. The sensor is highly resistant to light detection due to ambient light from high
efficiency light sources or from other light emitting industrial sensors. In addition, there are three user-selectable frequency
channels (A, B, or C) for crosstalk avoidance in side by side sensor mounting. The factory default channel is Frequency A.
