Allen Bradley Guardmaster 440G-L Series Solenoid Interlock Switch, Power to Unlock, 230V ac/dc, Actuator Included

Ensure superior protection for machine operators and keep your machine processes running smoothly with the 440G-L07262 Atlas 5 heavy-duty Solenoid Interlock Switch Allen Bradley Guardmaster. This unit is a positive mode, tongue-operated interlock switch. It works by securely locking the machine safety guard closed until the power supply is removed, and keeps it isolated while the door is open. This helps to prevent risk of injury to personnel by ensuring that access to hazardous areas is restricted while machinery is in motion.

The Atlas 5 is a heavy-duty switch and locking mechanism designed to withstand forces up to 5000N (1124lbs), providing greater stability and security for more demanding applications. It is ideal for use with machinery which does not come to an immediate stop, or machines that would be damaged by premature interference. This safety switch features a unique patented self-aligning head which can tolerate actuator misalignment and is particularly useful for heavy guard doors and gates.

The 440G-L07262 Atlas 5 switch has M20 conduit entry, 2NC safety contacts and 1NO auxiliary contact. It has a standard actuator made of robust stainless steel for optimal durability. This unit has a high holding force of 3850N (865 lbs) and power-to-release functionality. Solenoid voltage is 230 V ac/dc, and the solenoid contacts are 2NC/1NO. The housing material is made of resilient die-cast alloy, making it highly suitable for use in harsh environments. This safety switch has the standard model type and the enclosure has an ingress protection rating of IP65. The operating temperature is -10°C to +60°C (14°F to +14°F).

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.

A solenoid interlock switch is a type of safety switch with an internal solenoid; a wire coil which converts electrical energy to mechanical. This type of mechanism limits access to dangerous areas where machinery may be functioning by ensuring that that barriers remain securely shut. The safety guard can only be opened through either energising (Power to Release) or de-energising (Power to Lock) the solenoid with an external signal. They are often used in industrial environments, for example with high inertia rotating machines.
