TE Connectivity MTA-156 3.96mm Interconnect System

MTA-156 (Mass Termination Assembly) 3.96 mm pitch connector system for labour and cost saving mass termination of wires in wire-to-board and wire-to-wire applications. These MTA-156 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-156 IDC connectors can be quickly assembled to 26 AWG to 18 AWG discrete wire or ribbon cable. The MTA-156 connector system consists of female IDC connectors and PCB headers. The housings of the IDC connectors are colour coded according to wire size
