Safety switches

The Allen-Bradley Guardmaster 440P range of safety limit switches comprises 14 models and features a 2 m pre-terminated side- or bottom-entry cable and a rugged, compact 22 mm metal housing.

The 440P range also offers a broad choice of operator configurations, such as dome, roller or cross-roller plunger and short-roller lever. Each member of the 440P safety limit switch series is equipped with positively driven contacts, making them ideal for both safety and standard switching applications.

When ganged together to provide two ‘normally closed’ circuits, or used in conjunction with a safety PLC, the 440P series can accommodate safety applications up to SIL3 and Cat4. Alternatively, the switches can be used in isolation for standard switching applications.

With an IP67 and NEMA 1 enclosure rating, the 440P safety limit switch series is built to withstand harsh operating environments - the 440P series is IEC approved, CE marked, UL recognised and TÜV approved.
