Allen Bradley Guardmaster 440P Series Telescope Interlock Switch, 1 NO/1 NC, IP66, Metal Housing

Accurately control machinery in your workplace with this interlock limit switch from Rockwell Automation's Allen Bradley range. The slow-action nature of this stop switch provides precise positioning and synchronisation of make and break points. It's operated by the sliding action of the guard or another moving object, which ultimately deflects the lever. For easy mounting, you can rotate the head in 90° increments before installation. The metal telescopic arm has a length of 303mm which extends to 900mm, making this a versatile choice.

• Minimum mechanical life of 10,000,000 cycles for durability

• UL (Underwriters' Laboratories)

NO (normally open) means the switch remains in an open position until an action forces it to close. NC (normally closed) means the switch remains in a closed position until an action forces it to open. NO/NC means the switch has one pair of normally open switches and one pair of normally open switches, so it offers both actions.
