Allen Bradley Guardmaster 440P Series Roller Interlock Switch, NO/NC, IP30, Polybutylene Terephthalate (PBT) Housing

Use this safety switch from Rockwell Automation's Allen Bradley range to protect machinery or gates from hazards. The roller actuator mechanism creates a break in the electrical circuit when it comes into contact with an object. This reliably stops automated equipment, preventing damage or worker injury. The switch's PBT (polybutylene terephthalate) thermoplastic casing is hard-wearing and it has a minimum mechanical lifespan of 10,000,000 cycles, so it's both long-lasting and low-maintenance. It has a range of uses, including door guards, crane arms and moving machine beds.

• Wide operating temperature range between -20°C and +70°C for use in demanding environments
• Choice of actuator positions provides flexibility of use
• IP30 (ingress protection) rating indicates the casing is protected from tools and wires greater than 2.5mm
• Compact size (54mm long) makes it suitable for installation in tight spaces

• UL (Underwriters' Laboratories)
• CSA (Canadian Standards Association)
