Euchner NZ1RS-511-M Safety switch, roller plunger, roller Ø 12mm Part number 079960

This safety switch uses a roller plunger with a 12mm roller diameter to detect the position of guards, doors or moveable machine elements. Actuation occurs when the plunger is depressed by an approaching cam or guard, causing the internal contacts to change state and feed a position signal into the safety circuit. It is typically fitted at the edge of guarding on industrial machinery where a mechanical, roller-actuated interlock is required.
