The Allen-Bradley 803-B64 rotating cam limit switch is designed with the Style B specific features of the 803 cam limit switches series. The main purpose of a cam switch is to control equipment that has rotating mechanisms or linear motions (rotational motion). The Allen-Bradley 803-B64 rotating cam limit switch is featured with a high protective enclosure such as the NEMA 4 or the NEMA 13. These two kinds of enclosures not only protect the unit from the entrance of regular particles including dust, dirt, fibers, fliers etc., but also protects the unit from contact with rain, ice formations, and corrosive substances and oils; the protections provided by these enclosures make this unit appropriate for both indoor and outdoor applications.

The Allen-Bradley 803-B64 rotating cam limit switch operates at 10 amps with snap action (1 N.O. - 1 N.C.). This unit has 6 cams and the minimum and maximum range of each of them is around 14 degrees to 346 degrees. The Allen-Bradley 803-B64 rotating cam limit switch specifically features a left shaft extension that can be modified for industrial applications that require a right shaft; it also possesses a maximum shaft speed of 150 Revolutions Per Minute (RPM). The 803-B64 limit switch design includes adjustable segments, and it is manufactured in durable materials such as heavy steel. Both of these characteristics provide durability, as well as a high resistance to vibrations and impacts. This switch has a length of 10 and ¾ inches (273 millimeters) and an approximate shipping weight of 53 pounds (24.0 kilograms) Other important features of the 803-B64 rotating cam limit switch include its external adjustment mechanism and snap action contacts.
