Heart of the Connector

The compact design of a 2mm pitch connector, the current capacity of a power connector, the global availability of a product range stocked in depth, the established high-reliability of a COTS connector system. Datamate T-Contact increases the connector range of choice in many demanding applications on land, sea and air.
