The 70234-125LF is a Metral® vertical header backplane connector designed for high-density interconnect applications. It features a 4-module configuration with press-fit termination, offering 250 contacts per 100mm connector length at a 2mm contact pitch, and supports 4 and 5 row versions. The connector operates over a temperature range of -55°C to +125°C with a current rating of 1A per contact (all contacts powered), and is designed in accordance with IEC 61076-4-104 and Telcordia GR-1217-CORE standards. The modular and scalable design enables flexible connector lengths without loss of contact position, while varying pin lengths provide first-mate, last-break capability. This connector is ideal for applications in data centers, industrial equipment, instrumentation, medical devices, and telecommunications systems where high signal density and electrical reliability are required.
