TE Connectivity MTA-100 2.54mm Interconnect System

MTA-100 (Mass Termination Assembly) 2.54 mm pitch connector system for labour and cost saving mass termination of wires in wire-to-board and wire-to-wire applications. These MTA-100 connectors are based on IDC (insulation displacement contact) technology allowing one-step assembly and eliminating the need for wire stripping saving both time and cost. Using production hand tooling these MTA-100 IDC connectors can be quickly assembled to 28 AWG to 22 AWG discrete wire or notched ribbon cable. The MTA-100 connector system consists of female IDC connectors and PCB headers. The housings of the IDC connectors are colour coded according to wire size.
