MTA Connector System TE Connectivity's (TE) 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. These connectors provide wire feed-through capability for daisy-chain applications. IDCs are used to terminate a 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, which are available in through-hole and surface-mount configurations. TE MTA connectors are ideal for household appliances, fitness equipment, garage door openers, gasoline pumps, coin changers, and vending machines.
