Rockwell broadens its family of rugged limit switches
28 April 2010
Rockwell Automation has added rugged metal bodied models in compact 22mm housings to its Allen Bradley 440P limit switch family. Suitable for both safety and standard sensing applications, these new limit switches have been designed for ease of installation in applications where space is limited. In addition, they feature positive opening-action contacts for safety applications, and slotted 20 – 25mm mounting holes to allow for various mounting options. The 440P series is also suitable for Category 3 or 4 systems when used with a safety monitoring relay or safety controller.
The expansion of the range consists of 14 new part numbers with a broad selection of operator types, including dome, roller and cross roller plunger, as well as short lever. All styles, except the level model, are available with panel mount threading. Two cable configurations are offered to optimise fit in tight spaces, in bottom cable style and side cable style options. These models feature painted metal bodies and meet NEMA 1 standards, as well as IP66 and IP67 (pollution degree 3). They are CE marked for all applicable directives, UL recognised and TÜV approved.
The 440P limit switch family now comprises four different body styles – 30mm metal, 22mm metal, 22mm plastic and 15mm plastic. The models also include a broad selection of operator types, circuit arrangements and connection options, which made the range ideal for a wide variety of applications.
