TE Connectivity Mass Termination Assembly (MTA) Connector System is a wire-to-board and wire-to-wire system based on insulation displacement contact (IDC) technology. MTA 100 connectors have contacts in a single row on .100 inch [2.54mm] centers, while MTA 156 connector contacts are in a single row on .156 inch [3.96mm] centers. The design features wire feed-through capability for daisy-chain applications. IDCs are used to terminate a wide range of conductor sizes. Ribbon cable can also be terminated when the appropriate receptacle assembly and strain relief cover are used. Header assemblies for board mount applications include right-angle and vertical mount products available in through-hole and surface mount configurations.
