ERNI Microstac Connectors

The ERNI MicroStac connector series features hermaphroditic mating design within a pitch of 0.8 mm.  Connectors and their mating connectors are identical. This reduces the bill of materials and also storage and handling costs.  The connectors are available in single-row and double-row variants.

The design calls for fast automatic Surface Mount Technology (SMT) assembly.  MicroStac connectors are available for Board-to-Board heights of 3 mm and 5 mm. Despite their small size, MicroStac connector contacts offer large radiating surfaces to provide a high current rating.  A secure mating of 1.5 millimetres and the high contact force ensure reliability.
