Versatile safety switching from Rockwell Automation

A new range of Allen-Bradley Guardmaster safety limit switches—the 440P compact metal 22mm series. Comprising 14 models, the new 440P series features a two-meter pre-terminated side- or bottom-entry cable, and a rugged, compact 22mm metal housing. The new safety limit switch series also boasts a broad choice of operator configurations, such as dome, roller or cross-roller plunger, and short-roller lever. Each member of the new 440P safety limit switch series is equipped with positively driven contacts, making them ideal for both safety and standard switching applications.

According to Gary Milburn, Rockwell Automation Safety Area Manager, the new 440P safety limit switches are extremely versatile—both functionally and from an installation perspective. “When ganged together to provide two ‘normally closed’ circuits, or used in conjunction with a safety PLC, the new 440P series can accommodate safety applications up to SIL3 and Cat4,” he said. “Alternatively, the switches can be used in isolation for standard switching applications.”

The 440P series’ pre-terminated cable and compact industry-standard 22mm housing construction permit simple and quick installation, especially in hard-to-access areas. “The pre-terminated cable drastically reduces wiring requirements and minimises installation time,” explained Milburn. “This means applications can be brought on line sooner.” Further installation flexibility can be realised thanks to the 440P’s slotted mounting holes, which permit a wide variety of mounting orientations. Additionally, some of the new 440P range is available with a threaded panel-mount configuration.

Boasting an IP67 and NEMA 1 enclosure rating, the new Rockwell Automation 440P safety limit switch series is built to withstand arduous operating environments. Importantly, the 440P series is IEC-approved CE-marked, UL-recognised, and TÜV-approved.

The new 440P safety limit switch range complements the existing Rockwell Automation limit switch offering, which now comprises four body styles—30mm metal, 22mm metal, 22mm plastic, 15mm plastic. With a broad selection of operator types, circuit configurations and connection options, the Rockwell Automation limit switch family provides industry with the most versatile solution for safety and standard switching applications.
