Micro-D Connectors, 1.27mm Pitch Connectors
Board-to-Board Connectors, Wire-to-Wire Connectors, Wire-to-Board Connectors
1.27 mm high-density connectors are manufactured in accordance with GJB2446A / MIL-C-83513 standards and use a metal-shielded design comparable to U.S. MDM connectors. They are available in configurations from 9 to 144 contacts, covering 11 standard layouts, and support board-to-board, wire-to-board, and wire-to-wire connections. These rectangular connectors use flexible twisted contact pins to improve contact stability in high-density layouts. Their compact structure supports use in equipment with limited space and vibration resistance requirements. PCB tail options can be customized according to different installation needs.
