Robust Amphenol H4SFC2DM DC Connector with UL 6703 Certification and Low Resistance RADSOK Contacts

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 AISTs H4 connector, the Amphe-PV H4 Plus offers enhanced durability, compatibility with the entire AIST PV product line, 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 accepts wire gauges from 14AWG/2.5mm to 8AWG/10mm and features an IP68 rating. By integrating features like gland nuts, environmental gaskets, wire-retention collets, and contacts for multiple wire gauges, the Amphe-PV H4 Plus reduces part count and generates cost savings. It is suitable for all PV modules and installations across various end-markets.
