Product Description

The Mitsubishi AC12B cable assembly, essential for connecting A Series PLCs to extension racks, is a 1.2-meter (120 cm) cable weighing 1.19 lbs (540.0 grams) that ensures efficient and safe signal transmission via high-conductivity copper conductors, high-temperature, flame-retardant insulation, and EMI/RFI shielding (foil or braid). Suitable for machine control applications in temperatures from -10C to 70C (14F to 158F), its plug-and-play design facilitates quick and reliable extension rack connections.

Is Your Device Showing These Signs?

The Mitsubishi AC12B commonly experiences failures related to the IPM (Intelligent Power Module), resulting in compressor malfunction and inefficient cooling. Capacitor degradation on the control board is a frequent problem, causing erratic operation and communication errors within the HVAC system. Thermistor drift leads to inaccurate temperature readings, impacting climate control performance. Fan motor failures and refrigerant leaks are also typical issues that require immediate attention to restore optimal functionality. Replacement of the affected components and thorough system diagnostics are essential for effective repair.
