Durable solar connector Amphenol H4SMC4DM featuring ratcheting gland back nut and multi gauge wire support

Product Overview

The Amphe-PV H4 Plus from Amphenol Industrial Sustainable Technologies (AIST) is a robust, dual-certified DC connector designed for photovoltaic (PV) modules and installations worldwide. Building on the legacy of the H4 connector, it offers enhanced durability, Amphenol-compatible mating, and Amphenols low resistance RADSOK contact technology. Key improvements include a ratcheting gland back nut to prevent backspin, an enhanced sealing grommet for superior wet leakage performance, and optimized contact design for long-term stability. This connector supports wire gauges from 14AWG/2.5mm to 8AWG/10mm and boasts an IP68 rating. By integrating features like gland nuts, environmental gaskets, wire-retention collets, and multi-gauge contacts, the Amphe-PV H4 Plus reduces part count and offers cost savings.
