Function

The series 28 family of sensors can be universally used. It has a large range of models that allows it to be integrated into any automation
environment. The sensors are contained in sturdy water resistant plastic housings with multiple fastening options and scratch resistant optical
cover. Features such as a timer function, and functions including a light/dark switch, sensitivity adjuster and highly visible status LEDs make for
less effort on the part of the user and streamline installation, setup and operation. Just about any task associated with positioning, moving,
conveying and monitoring can be accomplished with these sensors.
