Description
The All-O-Matic LSH-300 Limit Switch Wire Harness is a direct replacement harness designed to restore reliable electrical communication between the limit switch assembly and the gate operator control system. This harness supports accurate open and close limit sensing, helping the operator stop at the proper travel points during each cycle.
Over time, limit wiring can become worn, damaged, loose, or degraded from vibration, service work, moisture exposure, or general use. Replacing the harness helps reduce intermittent limit errors, false trips, and inconsistent gate travel behavior, making it an important service part for maintaining dependable operator performance.
This replacement harness is intended for All-O-Matic gate operators using the LSH-300 limit switch configuration, including compatible SW-300 AC and SW-300 DC service applications. It is ideal for technicians, installers, and maintenance teams servicing commercial, residential, or high-cycle access control systems.
