Contact Conductivity Parameters Of Heavy-duty Connectors

Contact Resistance

Contact resistance refers to the resistance generated at the contact point between two conductors. Two issues should be noted when selecting heavy duty automotive electrical connectors. First, the contact resistance specification for heavy duty 12v connectors is actually the contact resistance itself, which includes both the contact resistance to the conductor and the resistance between the conductors. Since conductor resistance is generally low, many heavy duty 12 volt connectors specifications refer to the contact-to-conductor resistance as the contact resistance. Second, in circuits connecting small signals to 12v heavy duty connector, it is crucial to pay attention to the testing conditions under which the given contact resistance specification for heavy duty crimp connectors was tested. This is because the contact surface of heavy duty waterproof electrical connectors may have an oxide layer, oil, or other contaminants, and film resistance will be generated on the surfaces of both contact points of heavy duty 2 pin connector.
