The 803-NK33 is rotating cam limit switch manufactured by Allen-Bradley and belonging to the 1980 series. These are pilot machines that are meant for heavy-duty material handling mechanisms, bridges, mechanical presses, locks & dams, rotary tables, packaging machines, and a variety other applications. The moment any motion is expressed in the shaft rotation either via the gear train, directly, or through the roller chain, the 803-NK33 limit switch simplifies the process of opening or closing independent circuits at the preferred position. Just like the majority of other limit switches, the 803-NK33 is accessible in a number of enclosures, including NEMA 1, 4 & 5, 7, 9, and NEMA 12 ratings, and has an option for delivery with 2 to 40 circuits. For this reason, the device is perfectly designed to meet a huge number of engineers’ specifications. The NEMA Type 4 watertight gate-hoist enclosure, for example, is made of 10-gauge welded stainless steel plates.  Additionally, every part of the device is a corrosion resistant metal, or it is modified to resist corrosion. The exterior components are constructed from stainless steel, brass, or bronze, and the 803-NK33 is designed in an innovative way, allowing it to be supplied with 3, 6, 12, or 18-inch incremental control.

The 803-NK33 Rotating Cam Limit Switches are heavy duty control circuit devices that are meant for machines with a recurring cycle of operation, where motion is connected to shaft rotation. This product is designed to trigger contact actuation at different positions throughout shaft rotation. These Rotating Cam Limit Switches are made up of powerful specs that make them ideal for long life and heavy-duty operation; the 803-NK33 device specifically is delivered in six various styles to help users meet a wide range of applications; therefore, every style is designed to use the cam which is fixed on the shaft. When the shaft rotates, the cams responds by actuating the contacts. Numerous alternatives and adjustments are accessible for most applications. These applications include assembly and packing Machines, steel and Heavy Metals manufacturing, Injection Molding Machine, punch presses and in waterway Gate or Lock Operations.
