Allen Bradley 440P-CRPB12B GuardMaster Safety Limit Switch

Product Introduction

The Allen Bradley 440P-CRPB12B Guardmaster Safety Limit Switch is a compact IEC-style safety device designed for machine guarding, position detection, and industrial safety interlocking applications. It is engineered to provide reliable mechanical switching in environments where accurate position feedback and safety circuit integrity are critical.

This model features a full switch assembly, including both head and body, with a top push roller actuator designed for smooth mechanical engagement. The break-before-make (BBM) contact design ensures that safety circuits open before auxiliary circuits close, providing a higher level of protection in safety-related control systems.

Built with a robust plastic housing, the switch is suitable for industrial environments requiring durability, consistent performance, and resistance to mechanical stress. Its multiple circuit configuration allows flexible integration into safety systems, making it suitable for machine guarding, conveyor systems, and automated equipment where reliable position sensing is required.
