About 803-B2RH

The 803-B2RH Bulletin 03 rotating cam limit switch comes with a rotating shaft and a spring cam roller that is embedded in the contact base and it features a fully functional circuit. This state-of-the-art product is manufactured by Allen Bradley; once the unit makes a revolution, the cam is triggered to activate the contact. The Allen-Bradley 803-B2RH is rated for Type 1 and Type 4 & 13 NEMA enclosures and comes with an approximate shipping weight of 25 11.9 kilograms, which is equivalent to 25 pounds. This allows the product to be used as a heavy duty control circuit device on appliances that require repetitive cycles of operation where motion is correlated to the revolution of the shaft. For this reason, the 803-B2RH is used in locks, rotary tables, mechanical presses, packing machines, and injection molding machinery. Additionally, the product can be used in steel heavy and metals. The 803-B2RH rotating cam limit switch comes with a timing adjustment, an internal dwell, and the Left shaft extension standard. The timing setting is influenced by the position of the cam on the shaft once the shaft is activated by the cam. The circuit is initiated in motion by the lobe that presses against the cam roller assembly. In most cases, the lobe is above the cam segments. Note that the dwell time is determined by the position of the cam segment and the vastness of the cam lobe. Dwell time is defined as the duration required for the cam lobe to activate the circuit.



The 803-B2RH is designed in a unique way so that it has a high shaft speed that ranges between 150 and 400 Revolutions Per Minute (RPM). The device is from the SPDT family (single pole, double throw), and a snap action that comes with a 10A. This implies that once the cam lobe brings the cam roller into operation, the contacts snap over, forcing the Normally Open (NO) contact to close and the Normally Closed (NC) contact to open. Ensure that the dwell modification and internal timing adjustments are made when the device is not in operation. While making adjustments, ensure that the cover is detached, cam bolts are loose, and the cam is adjusted to the appropriate position by revolving them. Once the cam is in the right place, tighten the bolts and replace the module’s cover.
