Millipacs® Vertical Headers

Millipacs® is a 2.00 mm modular board to board or cable to board Interconnection system in Hardmetric configuration designed in accordance with IEC 917 and IEC 61076-4- 101 and Telcordia GR-1217-CORE standards.

2mm HM connector is one of the most popular backplane connector system. Millipacs® series offers attractive propositions for all market segments due to the cost effectiveness, user flexibility, standardization and availability of its broad range. Millipacs® connector system is extensively used for chassis-based packaging in the communications, data, medical and industrial & instrumentation segments.

Millipacs® series HM vertical headers are offered in standard signal modules of 5 and 8 rows. 5 row modules are available up to maximum of 125 signal contacts and 8 row modules are available up to maximum of 200 signal contacts per 50 mm length. Besides signal module, hybrid modules are available with signal pins, power and coax contacts. Vertical header mates with right angle receptacle, vertical receptacle and cable connector via shroud.
