Product Description
The Allen-Bradley 803-A10, a heavy-duty rotating cam limit switch from Rockwell Automation's series 803 family, is designed for shaft-driven mechanisms. This ten-circuit device uses ten eccentric, spring-loaded cams to open its 25A normally closed double break contacts. Each cam, consisting of two adjustable segments, is mounted on a shaft with a maximum rotational speed of 150 RPM, which can be modified using gear reducers. Contact actuation can be initiated at various points within the 360-degree rotation cycle, with adjustable dwell angles from 14 to 346 degrees. Suitable for applications like presses and injection molding machines, the Type 1 enclosure (27.25 X 22 X 18.44 inches) features a left-side shaft extension and internal timing and dwell adjustments accessible by removing the cover and loosening cam bolts. The N.C. contacts operate at 50/60 Hz with AC voltage between 120-600V and DC voltage between 115-250V, offering durable bidirectional operation and versatile mounting options.
Is Your Device Showing These Signs?
The Allen Bradley 803-A10 encounters common failures such as coil burnout due to overvoltage or inrush current, resulting in contactor malfunction. Contact erosion from repetitive switching of inductive loads causes operational failure, demanding contact replacement. Mechanical wear in the armature assembly leads to sluggish response or failure to actuate, necessitating component refurbishment. Overheating due to inadequate ventilation or excessive cycling degrades insulation, causing short circuits and requiring complete unit replacement. Inspect wiring connections for corrosion or looseness, as these contribute to erratic operation and system downtime.
Technical specifications
The Allen-Bradley 803-A10 is a robust, ten-circuit rotating cam limit switch designed for shaft-driven machinery. It uses adjustable cams to control its normally closed contacts, allowing for precise actuation timing and dwell angles within a 360-degree rotation. Suitable for heavy-duty applications like presses, it features a durable enclosure, adjustable internal settings, and versatile mounting options.
Our Repair Process for the
803-A10
Our repair process for the Allen Bradley 803-A10 begins with a thorough inspection of wiring connections for corrosion and looseness, addressing potential sources of erratic operation. We then assess the coil for burnout, a common failure mode due to overvoltage or inrush current, and replace it as needed. Contact erosion, resulting from repetitive switching of inductive loads, is evaluated, and contacts are replaced to ensure proper operation. Mechanical wear in the armature assembly is addressed through component refurbishment to eliminate sluggish response or failure to actuate. In cases of overheating leading to insulation degradation and short circuits, complete unit replacement is mandatory. This comprehensive approach guarantees the reliable restoration of your Allen Bradley 803-A10.
