    Allen Bradley Guardmaster Prosafe 440T-AKEYE100A Key for Trapped Key Interlocks


    The 440T-AKEYE100A Prosafe unit is a stainless-steel, weatherproof key which is designed specifically for use with the Prosafe Trapped Key Locks. It is Code A. With Prosafe switches the new keys are fully compatible with old style barrels, however old keys do not fit the new barrels.

    When used with a trapped key lock, this product forms a robust mechanical type of interlocking unit which is ideal for environments where electrical interlocking systems may be unsuitable or expensive to install and maintain, such as areas with explosive atmospheres.

    The Prosafe interlocking unit is a mechanical, industrial-grade solution for securing machine guards and providing essential protection for personnel. It ensures sequential access control, isolating the power supply to machinery when the gate or door is open.

    Features and Benefits:


    • Code A key for Prosafe 440T trapped key interlocking
    • 90º operation
    • Compact design and made of stainless-steel – sturdy, solid, reliable
    • These Prosafe interlocking components are supplied with dust seals and coded tagging

    The Prosafe range of products have been extensively tested for quality and durability, working seamlessly for 100,000 operations. They are also highly tamper-resistant, accepting only the original or equivalent new key for operation.

    How does a trapped key interlock work?


    A trapped key interlock is a simple sequential mechanical safety system for machine guards whereby a removable key is trapped in a control unit while the power supply is running. When the power supply is turned off it be rotated in the lock and withdrawn. While it is removed the power supply is isolated, ensuring that the machine cannot be restarted while the guard door is open. It can then be used to release the machine guard, allowing access to the machinery. After the guard is closed it can be removed and inserted back into the original control unit, thus allowing the power supply to be activated again. This type of interlocking system can withstand harsher environments than electrical interlocks and is often used in industrial settings where serious risk of injury can occur to machine operators.

    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.
