803-A6X

The Allen-Bradley 803-NK37 rotating cam limit switch is part of Allen-Bradley’s Bulletin 803 series of rotating cam limit switches. It is designed for a variety of heavy-duty control and manufacturing requirements, and users can custom order it with special features for specialized applications. The 803-NK37 is made to be as versatile and rugged as possible. All of its switches can rotate clockwise or counterclockwise and they and the cams rotate and move on heavy-duty precision bearings. These parts need minimal maintenance if they are properly installed and used.

Each of the 803-NK37 rotating cam limit switch’s cams can be set and adjusted independently and the whole switch can be mounted and used at any angle on any plane surface. The 803-NK37’s heavy-duty contacts can be double-break or snap-action contacts, and their dwell time settings can be adjusted at angles rated anywhere between 11 and 360 degrees. The rotating cam limit switch is perfect for assembly lines, packing and packaging machines, punch presses, steel forming, and similar applications that involve rotation and repetitive cycles in their operating processes. The 803-NK37 rotating cam limit switch possesses technology that lets it sense the rotating motion of the bigger machine it is attached to and that lets it coordinate its own motion with that of the bigger machine. This allows it to open and close at different angles and at different points in the big machine’s rotation and to initiate other functions. This makes the 803-NK37 ideal for putting lids on can and bottles or sealing boxes and bags.
