Allen Bradley 440G-L07263 Safety Switch - Atlas 5

Product Details

Allen Bradley Guardmaster 440G-L07263 Atlas 5 Solenoid Interlock Switch

Give your machine guard a safety upgrade with the 440G-L07263 Atlas 5 Solenoid Interlock Switch by Allen Bradley Guardmaster. This unit is a positive mode, tongue-operated interlock switch which provides essential stability and security for more demanding applications. The Atlas 5 heavy-duty switch and locking mechanism is expertly designed to withstand forces up to 5000N (1124lbs). This safety switch features a unique patented self-aligning head which can tolerate actuator misalignment, making it perfect for heavy guard doors and gates.
The 440G-L07263 Atlas 5 guard-locking switch has 2NC safety contacts, 1NO auxiliary contact. This standard model has M20 conduit entry and features a standard type actuator made of robust stainless steel for superior durability. The solenoid voltage is 110 V ac/dc, and the solenoid contacts are 2NC/1NO. This safety interlock switch has a holding force of 3850N (865 lbs). It is highly suitable for use in harsh environments due to the housing material, which is made of resilient die-cast alloy. The operating temperature of this safety switch is -10°C to +60°C (14°F to +14°F) and the enclosure has an ingress protection rating of IP65.
This safety switch is perfectly suited for use with machinery which does not come to an instant stop, or machines that would be damaged by premature interference. The Atlas 5 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 ensure that access to dangerous areas is restricted while machinery is in motion, reducing risk of serious injury to personnel.

How do Solenoid Interlock Switches work?

Solenoid interlock switches work by having their internal solenoid energised (Power to Release) or de-energised (Power to Lock) by an external signal. The solenoid is a wire coil which converts electrical energy into mechanical energy. These types of safety switches are often used in industrial environments on machine guards to monitor the barrier status and limit unsafe access to hazardous equipment. They ensure that safety barriers remain securely locked while dangerous processes are running. They are useful with machinery that does not instantly stop, such as high inertia rotating machines.
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.
