TE Connectivity AMP 646445-1 Z-PACK 2mm HM Receptacle Connector

The TE Connectivity AMP 646445-1 is a high-density board-to-board receptacle designed for backplane interconnection in electronic systems. Part of the Z-PACK 2mm HM series, this 200-position connector features a right-angle PCB mounting design that supports space-efficient integration into compatible electronic assemblies.

With eight rows, 25 columns, and a 2mm contact pitch, the connector provides multiple signal connections within a compact footprint. Its press-fit termination supports PCB installation without conventional soldering at the connector interface, making it relevant for specialised backplane designs, equipment maintenance, and replacement component sourcing.
