Johnson Controls WHA-PKD3-200C Wire Harness

The Johnson Controls WHA-PKD3-200C Wire Harness is a 6.5-foot (78-inch) field-replacement cable specifically engineered for HVACR control wiring and pressure transducer integration. This heavy-duty harness utilizes a 3-pin Packard connector, ensuring a moisture-resistant, secure-lock interface that prevents signal loss or intermittent connectivity in high-vibration rooftop units and industrial chillers. Designed for seamless P499 series transducer compatibility and System 450 modular controls, this assembly simplifies the wiring process for technicians by providing a pre-terminated solution that meets factory specifications. The multi-conductor shielded cable design protects low-voltage signals from electromagnetic interference (EMI), which is critical for maintaining accurate sensor readings in complex electronic control systems. By utilizing this OEM-grade wire harness, contractors ensure reliable power distribution and signal feedback between Johnson Controls sensors and the primary HVAC control module, reducing diagnostic time and preventing long-term equipment downtime.

Key Benefits

• Factory-Terminated Connectivity: Features a high-integrity Packard connector for a plug-and-play interface with compatible pressure sensors.
• Extended Lead Length: The 6.5-foot cable allows for flexible routing through conduit and cabinets in larger commercial installations.
• Industrial Durability: Rated for high-temperature environments and resistant to common HVAC oils and chemical exposure.
• Signal Integrity: Minimizes voltage drop and signal noise, ensuring the electronic controller receives precise data for system cycling.
