Allen Bradley Guardmaster Safety Interlock Switch, 2NC, 600V AC - 440K-E33080
Enhance personal and mechanical safety using this safety interlock switch from Rockwell Automation's Allen Bradley Guardmaster range. It protects workers by preventing access to a machine in the event of a hazardous situation. The switch has two NC (normally closed) contacts that send a stop signal to the machine. Its dual-entry, rotatable head offers 8 different options for actuator entry, giving you flexibility in your set-up. Thanks to its very small dimensions of 75 (length) x 25 (width) x 29mm (depth), you can use this switch in tight spaces where a normal safety lock wouldn't fit.
