440G-T27132, Allen Bradley Guardmaster 440G-T Series Solenoid Interlock Switch, Power to Lock, 110V ac

Allen Bradley Guardmaster 440G-T27132 TLS-2-GD2 Solenoid Interlock Switch

Optimise your machine guard safety system and ensure maximum protection for machine operators with the 440G-T27132 TLS-2-GD2 Solenoid Interlock Safety Switch by Allen Bradley Guardmaster. This reliable and cost-effective guard-locking switch is perfect for use with machines which do not stop instantly, or which may be damaged by interference while in motion. It is also suitable for use with PLCs

The TLS-2GD2 safety switch is a positive mode, tongue-operated interlock switch. It ensures that guards are safely locked while machinery is in motion. The barrier can only open when the internal solenoid is de-energised by an external signal. It also keeps power isolated when the door is open. This helps to prevent the risk of personnel entering a dangerous area where injury may occur. This safety interlock switch has 2 entry slots on the head and it can also be rotated to offer 4 actuator entry positions. A blanking plug is provided to seal the unused slot.

The 440G-T27132 TLS-2-GD2 safety switch has Power to Lock functionality, 2NC safety contacts, 1 NO auxiliary contact, and M20 conduit entry. It has a high holding force of 2000N (450 lbs), which offers vital stability and security for the safety barrier. The solenoid voltage is 110V ac/dc, and the solenoid contacts are 1NC/1NO. The housing is comprised of resilient UL approved glass-filled PBT. This versatile unit has an environmental protection rating of IP67, which ensures that it is fully protected against ingress of dust particles and it can withstand temporary immersion in water. This makes it highly suitable for use in wet environments where regular wash downs are necessary. The operating temperature for this switch is -20°C to +60°C (-4°F to +140°F). It has a rated insulation voltage is 500V and the thermal current is 10A.

Note: Actuator is not supplied and must be ordered separately.

Warning: With the ’power to lock’ function, provisions are required to ensure that a dangerous situation cannot result from open circuit faults or power cuts.

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.

What are Solenoid Interlock Switches?

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.
