Durable Amphenol M39029/63-368 connectors with integrated grounding strips and shock vibration resistance
Product Overview
Positronic MACH-D connectors are high-performance D-Subminiature connectors designed for demanding applications in harsh environments. Featuring precision-machined aluminum or stainless steel shells, these connectors offer superior EMI shielding and mechanical ruggedness against shock and vibration. They provide excellent electromagnetic compatibility (EMC) through integrated grounding strips and are available in IP67 configurations for fluid and dust ingress protection. The MACH-D series offers standard density (MCD), high density (MCDD), and combination/mixed density (MCBX) options, all intermateable with M24308 standard D-Subs and often exceeding their performance requirements. These connectors are critical for applications where reliability and certainty are paramount, from aerospace and defense to industrial and medical sectors. Positronic's commitment to 'The Science of Certainty' ensures failsafe product performance, design flexibility, and responsive support.
