The Archer range from Harwin is a series of 1.27mm (0.05”) pitch connectors, offering single and double row
options at half the PCB footprint of a 2.54mm (0.1”) pitch connector. These Industry Standard connectors
are backed by Harwin’s outstanding service, quality and distribution network, and are an ideal choice for a
miniature alternative to larger pin header and socket connections.

and horizontal orientations, for board-to-board connections.
1.27mm (0.05”) pitch in both directions, with 0.4mm square male
pins. Jumper Sockets and Pin Header Variants also available.
M50 Polarised – Double row connectors for board-to-board,
with added shrouding and a polarisation feature.
M50 IDC – Cable connectors for 0.635mm pitch ribbon cable,
and associated board connectors with securing latches and
polarisation, for cable-to-board connection. Complete cable
assemblies also supplied as standard.
M52 – Single and Double row pin headers and sockets, in vertical
and horizontal orientations, for board-to-board connections.
1.27mm (0.05”) pitch along the connector, 2.54mm (0.1”) between
connector rows using 0.46mm square male pins. Pin Header
