51202901-100 | Honeywell | 2-Wire Wire Harness Connector Assembly

Product Description

The 51202901-100 wire harness connector assembly is a factory-engineered 2-wire connection component developed by Honeywell for legacy and installed Experion PKS and C300 control architectures. It is designed to provide dependable point-to-point electrical continuity between controller subsystems and associated field wiring.

Although this part has been discontinued by the manufacturer, it remains widely used in installed Honeywell systems where mechanical compatibility, wiring integrity, and signal stability must be maintained without redesigning existing cabinets or harness layouts.

The connector uses an industrial-grade housing and contact structure optimized for low-resistance transmission, mechanical retention, and long-term stability in control room and plant environments.

Frequently Asked Questions

Is the 51202901-100 still manufactured by Honeywell?
No. The 51202901-100 has been officially discontinued, but new surplus units are still available from qualified suppliers.

Can this connector be substituted with a generic 2-wire connector?
Generic connectors may not meet Honeywell’s mechanical tolerances or EMI shielding requirements. OEM-matched parts are strongly recommended for system integrity.

Does this part carry signals or power?
It can be used for either, depending on system design, as it functions as a passive 2-wire harness interface.
