Fretting corrosion/Micro fretting corrosion

This is a phenomenon in which the metal contact surfaces rub against each other very small due to vibrations, etc., and abrasion powder is generated, and corrosion progresses. In connectors, there is a problem that the contact resistance increases due to the damage of the plating due to the abrasion powder generated and the oxidation of the abrasion powder.

To combat fretting wear, we offer the Z-Move structure ™ series of connectors, whose contacts follow vibration-induced movement. This product is useful for Board to Board Connector connections under vibration, particularly when there is concern about resonance at the connector mounting area.
