Hard Metric Connectors: har-bus® HM

Hard metric connectors in 2 mm contact pitch based on IEC 61076-4-101 with press-in technology.

What is a Hard Metric Connector?

Hard Metric or HM connectors are PCB connectors that are standardized to IEC 61076-4-101. These connectors have 2 mm pitch or contact spacing. These connectors have 5 or 8 rows and are used in backplane applications.

Hard Metric Connectors for Industrial Applications: har-bus® HM

HARTING offers the 5-row and 8-row backplane connector with accessories according to the IEC standard. These connector are used e.g. in CompactPCI applications. Contact counts from 55 to 308 contacts are available in 13 different pin lengths. User specific contact loadings are available on request.

For higher current requirements a 4-pin version with up to 20 A @ 70°C per contact offers high current transmission on PCBs in a small form factor.
