Allen Bradley Guardmaster 440K Safety Interlock Switch, 2NC/1NO, Keyed Actuator Included, Glass Filled PBT

Give your machine guard door a safety upgrade with the Trojan™ 5 Safety Switches by Allen Bradley Guardmaster.

The Trojan 5 switches are universal tongue (or key) operated interlock switches which prevent access to hazardous areas where machinery may be in motion. They have dual key entry slots and rotatable heads, which can be moved by releasing the cover screws, and offer four actuator entry options. They are designed to fit the leading edge of sliding, hinged or lift-off guards. They are easy to install and are operated by inserting a specially-profiled stainless steel key that is permanently attached to the leading edge of the guard door. The actuator is tamper resistant and will only operate when mounted to the guard, ensuring optimal security and stability.

These switches have 3 sets of contacts: 1 NO (Normally Open) / 2 NC (Normally Closed). They are sealed to IP67, making them suitable for use in wet environments where machinery is regularly washed down. They are also fully protected against ingress of dust. All switches come with an actuator.

Cat. 1 device per EN 954-1 dual channel interlocks suitable for Cat. 3 or 4 systems.

Forced guided contacts - complies with EN 1088, IEC 947-5-1
CE Marked for all applicable directives, cULus, TÜV, and CCC

EN 954-1, ISO 13849-1, IEC/EN 60204-1, NFPA 79, EN 1088, ISO 14119, IEC/EN 60947-5-1, ANSI B11.19, AS 4024.1.

The 440K-T11205 Trojan 5 tongue interlock switch has 3 contacts: 2NC/1NO, Break Before Make Action (opens the first set of contacts before closing new contacts), a standard type actuator, and 6 Pin M12 Micro QD conduit entry.

Safety Interlock Switches work by keeping machine guards and gates securely locked until the power supply is disconnected. They can also keep the power isolated while the barrier is open. This minimises risk of injury to operators as they are restricted from accessing dangerous machinery which may be in motion. They can also be used to monitor the position or status of the guard. They are usually used in industrial settings, such as safeguarding factory production lines. They can vary in lock type, maximum current and voltage, and housing material. Safety-rated interlock switches are specifically designed to meet high safety standards. Allen Bradley Guardmaster switches are built to global standards to provide exceptional quality and reliability.

This device can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster.
Guardlink simplifies and reduces the connection time of the safe access system, whilst providing real-time diagnostic information over Ethernet IP. This makes it simple to identify the location of the device that has tripped the system, thus reducing downtime, and improving the machines overall efficiency.
