Solar power applications beckon PV connectors

The new connector is an enhanced version of the Amphenol Industrial H4 UTX Solar Connectors. These connectors now support a ratcheting gland nut which prevents backspin once the nut is tightened. Other improvements include environmentally safe gaskets and wire-retention collets. Contacts can accept wire gauges from 14AWG to as large as 8AWG (2.5mm² to 10mm²), providing higher current capabilities and lower contact resistance than conventional solar connector solutions.

Typical contact resistance is only 0.25mΩ, resulting in extremely low power losses. Connectors mate quickly and easily with an audible snap‑lock mating system that helps insure an error-free installation.

Amphenol Industrial’s RADSOK Technology insures a high contact, low resistance connection by placing a web of about two dozen tiny beams running from the front to back of the female contact. As the male contact is inserted, the web wipes the male contact clean while providing solid multiple connections, imparting high current flow with minimal voltage loss.     

The H4 UTX Connectors provide very high reliability connections and are highly resistant to the harsh environments found in solar power installations, including resistance to extremes of heat, cold, immersion in water, ozone, salt, abrasion, UV, and sunlight.     

The connector meets all three of the highest certification standards on the market, allowing one solar connector to be used globally. Certifications include EN50521 TUV 1500V- Class A (All Access), UL6703 1000V (Americas) and JET 1500V (Japan). The H4 UTX are fully mateable with all existing H4 PV connectors.
