| Product List |
A range of 1.27mm (0.05) pitch connectors, male and female shrouded connectors for board-to-board and cable-to-board connection. All connector part numbers start with the series code M55. The socket connectors are twin-beam female contacts, and these mate to solid pin male connectors. All board mount connectors are double row and Surface Mount, supplied in tape-and reel packaging (pick-and-place caps included when applicable). All connector housings include location pegs for additional placement assistance on the PCB, and SMT side tabs for additional peel strength and strain relief when soldered down. Both male and female connectors are available in Vertical or Horizontal orientations, with 3 height options on the Vertical connectors. The range can therefore be used for parallel board-to-board (mezzanine layouts), right-angle motherboard-to-daughterboard, or co-planar / edge-to-edge layouts. All housings include polarisation within the design. All IDC female connectors are double row, available as individual connectors or horizontally mounted to a PVC ribbon cable. Connector housings feature a latch for quick and secure mating to the male half.
