When it comes to heavy-duty industry-specific applications, the Bulletin 803-F612T rotating cam switch can provide a solid alternative. The Bulletin 803 series by Allen Bradley is a series of control circuit rotating cam devices that are usually implemented with machinery that involves a repetitive cycle of consecutive operations. In such devices, the motion of the machinery is correlated to shaft rotation. These devices are used to initiate contact actuation at particular positions during the shaft rotation operation of any machine. The 803-F612T switch, in particular, is capable of operating well in either direction on any given plane. The Bulletin 803-F612T falls under the category of Style “F” rotating cam limit switches. These are 2 to 12 independent cam devices that feature 10 Ampere snap action contacts 1 N.O. -1 N.C. The Style “F” modification module requires a Type 1 & 13 enclosure; the 803-F612T rotating cam switch device offers around 150 RPM of maximum rotating shaft speed. The cam duration offered by the 803-F612T device has a minimum of 12 degrees and maximum of 348 degrees. A left-hand side shaft extension in the standard type of extension in the 803-F612T Style “F” rotating cam limit switch device.

The 803-F612T Style “F” switch has external timing & dwell adjustments. Both of the external timing as well as dwell adjustments can be done with the help of a screwdriver, and while the device is still in motion. The 10 Ampere snap action 1 N.O -1 N.C contacts are rated for the supply for 10 Ampere continuous current. Snap action contacts have NEMA rating designation as A600. When the snap-action contacts are used, the cam lobe is able to engage the given cam-roller for opening the normally-closed contact. The 803-F612T devices find its applications in a myriad of industry-specific applications including manufacturing, assembly, packaging, heavy metals, injection molding machines, locking operations, punching presses operations, and a variety of others.
