Overview

The G20 sensors enable reliable object detection over longer distances and are particularly well-suited for use in dusty environments thanks to the high operating reserve. They are compact, economical and offer an excellent price-performance ratio. The additional front LED and the rotary switches facilitate commissioning and operational checks.

The light/dark switching, adjustable sensitivity and configurable signal delay make the photoelectric sensors flexible for use in numerous applications. They are also fully compatible with each other in terms of mounting, as DC and AC/DC devices are available in the same design and with different mechanical mounting options.
