Description
This proximity switch provides a set of solid-state relays for controlling external circuits. The relays are driven between
open and closed states by sensing the position of a magnetic plunger.
To determine that the switching device is working correctly, the external circuits and controlled processes must be
monitored by independent measurements. The safety of any system incorporating the equipment is the responsibility
of the assembler of the system.
