Series 5000 Modular Photoelectric Sensors consist of two major components: a photohead and a power base. The photohead that houses most of the electronics can be quickly removed from the power base with a turn of a single screw. If an application changes, a switch to one of several other Series 5000 sensing modes is quick and easy—no rewiring or realignment. Six product families within the PHOTOSWITCH® Series 5000 product line can solve many difficult industrial photoelectric applications.
