803-A124X

The Allen-Bradley 803-A124X rotating cam limit switch features a double shaft extension and 12 circuits for maximum flexibility. This rotating switch is a Style A rotating switch, which can run at 150 RPM maximum shaft speed. It also has 25-A normally closed double break contacts and a cam duration that ranges from a minimum of 14 degrees to a maximum of 346 degrees, depending on the angle that a machine’s shaft rotation needs to complete its application. The enclosure ratings of the 803-A124X switch are Type 4 and Type 13 and it weighs around 20.4 kilograms or 45 pounds. Note that this cam limit switch can be mounted on any plane. This switch, when mounted, has the capacity to rotate in either direction. The 803-A124X switch also comes with a spring-loaded cam-roller assembly that is mounted directly on the contact base and with internal dwell adjustments and timing adjustments, though adjusting them is only done when the device is not moving. It is a hardy switch that is suitable for heavy duty and long-term use, which is ideal for use with machines using repetitive operation cycles, specifically those whose shaft rotation is correlated to its motion. Like any other 803 series switch, the Allen-Bradley 803-A124X rotating cam limit switch has an operating temperature range of -30 to 66 degrees Celsius, and a storage temperature range of -30 to 93 degrees Celsius. Its typical shaft torques are 7 lb-in when the cam roller rides up the cam ramp, 3 pounds on an inch when the cam roller rides on the lobe, and 0.5 pounds on an inch with the cam roller is in the valley.
