Product details
Allen Bradley Guardmaster MT-GD2 Safety Interlock Switch, Standard
Improve safe-access to machinery for operators and keep your guard door secure with the MT-GD2 Safety Interlock Switch by Allen Bradley Guardmaster.
The MT-GD2 switches are tongue (or key) operated safety interlocking devices. They are expertly designed to be fitted on the leading edge of hinged, sliding, and lift-off guards. This resilient interlock switch has a rotatable head and dual entry slots, providing eight different points for actuator entry to give you improved application flexibility. The head is also secured with tamper-resistant screws. This affordable and compact switch is 117 x 40 x 43 mm with DIN 50041 standard fixing centres and includes forced guided contacts. It is designed to be easily installed. It is also sealed to IP67, making it perfect for use in harsh industrial environments as it is fully protected from dust ingress and can withstand some immersion in water.
To operate the MT-GD2 interlock switch a specially profiled, stainless-steel actuator must be inserted. This should be permanently attached to the guard door. This device provides reliable electrical interlocking of the guard door and the machine’s control circuit. This ensures that power to the machine is isolated while the guard door is open, preventing access to dangerous areas where machinery is running and minimising risk of injury to personnel. This versatile switch can be used as part of a system for higher-risk applications as it is available with a variety of contact configurations.
Features and Benefits:
• 8 possible actuator entry positions including front and end entry, rotatable head
• Tamper-resistant screws
• Forced guided contacts - complies with EN 1088, IEC 947-5-1
• Die-cast metal body with painted zinc for enhanced corrosion resistence
• Contacts break actuation travel; 6mm
• Operating temperature: -20 to +80°C
• DIN 50041 footprint
• Sealed to IP67: fully protected against dust ingress and some water immersion
• CE marked in accordance with relevant European Directives
Approvals: UL, TUV
