Ensure superior guard interlocking for small machine safety barriers and protect personnel from entering hazardous areas with the 440K-C21098 Cadet 3 Tongue Interlock Switch by Allen Bradley Guardmaster.

This Cadet 3 interlock unit features a rotatable head with 2 entry slots, allowing up to 8 different actuator entry points for greater application flexibility. This unique switch has compact housing, making it highly versatile, and has industry standard fixing centers for effortless mounting. To operate the switch, the specially profiled key must be fixed to the machine guard door. This can then be inserted into the switch.

The 440K-C21098 safety switch has 2NC safety contacts, 1NO auxiliary contact, and break-before-make action. It comes with tough stainless-steel flat type actuator and has M16 conduit entry. The housing is red for easy visibility and is made of resilient UL approved glass-filled PBT. It is dust-proof and water-tight, giving it a high ingress protection rating of IP67. It has a voltage rating of 600VAC/DC. The Cadet 3 interlock switch is designed specifically to be fitted at the leading edge of hinged, sliding, and lift-off machine guard doors and provides superior protection for equipment and personnel.

• Dual entry rotatable head which offers 8 actuator entry positions
• IP67 rated, making it ideally suited for wash-down environments
• Compact size, perfect for small lightweight guards
• Easy installation to save you valuable time
• Industry standard fixing centres to DIN 500, ensuring ease-of-mounting
• GD2 style available for harsher applications

Note: A blanking plug is supplied for the unused key entry.
This device can be used with GuardLink, a new linking technology from Allen Bradley Guardmaster. GuardLink simplifies and reduces the connection time of the safety system while providing real-time diagnostic information over Ethernet IP. This simplifies the identification of the location of the device that has tripped the system. Thus, it reduces downtime and improves the overall efficiency of the machines. For more details, please refer to the GuardLink brochure.

Safety interlock switches work by securely locking guard doors and gates, preventing unsafe access to hazardous areas where machinery may be in operation. This helps to decrease the risk of injury to personnel and damage to machinery. They can also be used to monitor the status of the machine guard, and to ensure that machinery cannot start up or run while the guard door is open. They are often utilised in industrial applications, such as safeguarding factory production lines. They can vary in lock type, maximum current and voltage, and housing material. These interlock switches are specifically designed to meet high standards of protection.

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.
