What is the Contact Resistance of HYSF connectors?

HYSF connectors are precision-engineered for low signal loss. The maximum contact resistance is typically < 0.01 Ω (10 mΩ) per contact when new. This low resistance ensures minimal voltage drop and high signal integrity, which is crucial for sensitive instrumentation data.

In subsea telemetry, high resistance means signal degradation.

Specification: We maintain a strictly low contact resistance (typically 3-5 mΩ for power contacts and <10 mΩ for signal contacts).
Testing Method: Measured using a micro-ohmmeter across the mated pair (pin to socket) including the bulk resistance of the contact material.
Stability: Thanks to our high-quality Gold Plating, this resistance value remains stable even after hundreds of mating cycles, preventing the “intermittent signal” issues often seen in cheaper connectors.
