Product description

The Allen Bradley 440K-MT55085 is an MT-GD2 Guardmaster Tongue Interlock switch, a crucial component for ensuring machine safety. It is configured with 3 Normally Closed (NC) safety contacts and 1 Normally Open (NO) auxiliary contact, employing a break-before-make contact operation. The switch is housed in a durable die-cast alloy body with an IP67 enclosure rating, designed for resilience in harsh industrial environments. It typically includes an actuator, M20 conduit connection, and a 1/2in NPT adapter for flexible installation.

This safety interlock is vital for preventing accidental machine operation when access panels or guards are open, thereby protecting personnel. It is widely used in manufacturing environments, including assembly lines, robotic cells, and material handling systems, where safety interlocks are critical for compliance and operator well-being.
