Harwin has extended its M40 series of cable-to-board connectors
with lightweight, low-profile 1-mm pitch versions. The connectors feature phosphor
bronze contacts that are rated for currents of up to 1 A. Developed for designs
with densely populated PCBs stacked closely together, they target industrial
control/monitoring, communications infrastructure, industrial drives, and
consumer electronics.

The M40 connectors are available in single- and double-row options
with vertical and horizontal surface-mount configurations for the shrouded male
headers, enabling them to meet a variety of different layout requirements. Key
specifications include an insulation resistance of 100 MΩ, an operational
temperature range of –25°C to 85°C, and 50 mate/un-mate cycles.

female contacts are available off the shelf, with complete cable assembly
layouts on request, making them well-suited for prototyping or small-volume
runs, said Harwin. The connectors are supplied in either tube packaging or a
tape-and-reel format.
