Product Description
The Allen Bradley 803-B6RHW is a Bulletin 803 series rotating cam limit switch, a modified version of the Bulletin 803 Style "B," housed in a NEMA type 1 general purpose enclosure and weighing 31 pounds. Manufactured in 1980, it utilizes six operative circuits, a functional cam, and a rotating shaft (where cams are mounted) to actuate contacts. Unique to this switch is an external 48-tooth adjustment sprocket (145.64 mm pitch diameter) for easier position adjustment with chain drive mechanisms. Featuring a non-standard, right-hand shaft extension and a maximum shaft speed of 150 RPM, the switch employs snap-action contacts (rated at 10A constant current) labeled 1-4; contacts 1 & 2 close and 3 & 4 open when the cam roller engages the lobe. With 2 to 12 independent cam operators, the 803-B6RHW finds diverse applications in steel and heavy metal forming, punch presses, assembly and packing machines, and injection molding machines, initiating functions at varying points in a machine's cycle based on shaft rotation.
Is Your Device Showing These Signs?
The Allen Bradley 803-B6RHW push button commonly experiences issues such as contact degradation leading to intermittent or failed signaling, requiring contact replacement or cleaning. Actuator failure, stemming from mechanical wear or environmental factors, prevents proper switch operation and necessitates actuator replacement. Coil burnout, often due to voltage spikes or prolonged energization, disables the magnetic latching function, demanding coil replacement. Housing cracks or damage compromise environmental sealing, exposing internal components to contaminants and requiring housing repair or replacement. Wiring harness damage, including frayed wires or loose connections, disrupts electrical continuity and demands harness repair or replacement.
