Allen-Bradley 440K-MT55131 Safety Interlock Switch

The Allen-Bradley 440K-MT55131 (440K-MT55131) is a safety interlock switch designed for industrial safety and machine guarding applications. As an essential component within safety control systems, this interlock switch monitors the status of movable guards, gates, and safety doors to protect personnel and automated machinery from hazardous operating conditions. When a safety barrier or guard is opened during machine operation, the interlock switch isolates power or initiates an immediate stop command through the connected safety monitoring circuit, preventing access to moving parts and operational hazards. Engineered for robust industrial environments, this switch provides reliable position sensing and switching performance across manufacturing lines, robotic cells, assembly systems, and material handling equipment. With a total weight of 10 kg, it offers heavy-duty mechanical construction suitable for demanding plant floor installations. Incorporating genuine replacement components ensures seamless compatibility, maintains required safety integrity levels, and minimizes unscheduled downtime during maintenance, repair, and overhaul procedures.
