hm 2.0 – Hardmetric Connectors

High Contact Density
The hm 2.0 series of hardmetric connectors was developed in accordance with the international IEC 61076-4-101 standard. These shielded connectors have a pitch of 2 mm and are suitable for applications that require high contact density and reliability. Standardization ensures that the connectors are compatible with products from different manufacturers.

  • wide selection of types
  • modular connectors with a pitch of 2 mm
  • 5 or 8 signal rows
  • 12 different pin lengths
  • customized assembly layout as an option
  • available with or without shielding
  • supports a data transfer rate of up to 3.125 Gbps
  • robust design
  • accessories such as shrouds and coding keys

Overview CompactPCI Connectors

CompactPCI as the PICMG standard places high requirements on 19-inch high-end systems with passive backplanes as regards robustness, reliability, and performance. CompactPCI platforms are cost optimized, scalable, suitable for harsh environmental conditions, and highly durable. This is why system designers rely on robust, modular, standard-compliant CompactPCI platforms.

The PICMG® standards for CompactPCI provide specifications for hard metric connectors. ept’s hm2.0 connectors are optimally suited for use in CompactPCI applications.
