803-F412RB

The Allen-Bradley 803-F412RB heavy-duty rotating cam limit Style F switch with a Type 1 and Type 13 enclosure ratings, 4 circuits, and speed reducer with a gear ratio of 60:1. It comes with adjustable external dwell time and timing settings that the user can configure with a screwdriver even while the device is moving, as well as a spring-loaded cam-roller assembly that is mounted to the contact base that is installed on all Allen-Bradley 803 series switches. The Style F series that the 803-F412RB switch is part of has the following standard features: 10 Amp. snap action N. O. (normally open) and N. C. (normally closed) contacts, a minimum cam duration of 12° and a maximum one of 348°, a 150 RPM-rated maximum shaft speed, and a standard left shaft extension. The mounting of this cam switch is a plane and its mounting will not affect its rotation, because it can rotate either direction. The approximate dimensions of this switch are 7.06 x 4.81 x 2.41 inches and its weight is 12 lbs.

The typical shaft torques of the 803-F412RB switch are 3 inch pounds when the cam roller rides on its lobe, 0.5 inch pounds with the cam roller in its valley, and 7 inch pounds when the cam roller rides up its cam ramp. This switch has a storage temperature of -22-200 °F, as well as an operating temperature of -22-151 °F. Manufacturers can use the 803-F412RB switch with machines that come with operation cycles which are repetitive, specifically those who have correlated shaft rotation and general machine motion, such as punch presses, steel forming, injection molding, and assembly and packing.
