Allen-Bradley 440P-MRPB04B Limit Switch

The Allen-Bradley 440P-MRPB04B (440P-MRPB04B) is an industrial limit switch component designed for position sensing, machine interlocking, and process monitoring across automated manufacturing systems. Manufactured by Allen-Bradley as part of the 440P product line, this robust unit is engineered to detect the mechanical presence, travel limits, or displacement of moving machinery components, transfer systems, and production assemblies. It functions by converting mechanical motion into reliable electrical switching signals, enabling automated controllers and safety circuits to govern operational sequences and prevent mechanical overtravel. Constructed for demanding industrial operating environments, the switch provides dependable contact actuation and mechanical endurance in assembly lines, material handling equipment, packaging machinery, and industrial automation cells. The component integrates into standard industrial control architectures, interfacing with programmable controllers, safety modules, and relay circuits to ensure precise equipment timing and operational control. With a recorded net weight of 10 kg, the 440P-MRPB04B delivers durable construction suited for rugged installations where physical contact monitoring is essential to equipment protection and consistent operational performance.
