Allen Bradley Guardmaster 440G-S Series Solenoid Interlock Switch, Power to Unlock, 24V ac/dc, Actuator Included

The Spartan 440G-S36001 guard locking device is a positive mode and tongue operated switch that firmly locks safety guards while machinery is in motion and isolates power when the barrier is released. This helps to prevent unsafe access to dangerous areas for personnel and reduces risk of damage to equipment through premature interference. The mechanism can only be released when a signal is applied to the internal solenoid, which allows the tongue to be removed from the switch. The Spartan switch is a cost-effective solution which is perfectly suited for use with machinery that does not come to an immediate stop.

This Power-to-Release safety switch has a supply voltage rating of 24VAC/DC and 2NC Safety Contacts and 1NO Auxiliary Contact. It provides enhanced stability with a high holding force of 770N (173 lbs). Conduit entry is M20. The housing material is comprised of UL approved resilient glass-filled polyester, and this switch has an operating temperature of -20°C to 60°C. It has a thermal current of 10A.

• Includes a Standard type actuator made of stainless steel
• Environmentally sealed to IP67 rating, which makes it dust-tight and durable against some immersion in water
• Fast, easy troubleshooting with lid mounted status indication, LED provides visual indication of switch status
• Rotatable head in 4 possible actuator entry positions
• Ideal for use with hinge, sliding, and lift-off doors

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.
