The new UTX from Amphenol Industrial Solar Technologies (AIST) is a robust DC connector. The UTX is an evolution of AISTs well-known H4 connector and mates with the H4. UTX uses Amphenols low resistance RADSOK contact technology giving it the ability to accept wire gauges from 14AWG/2.5mm to 8 AWG/10mm. An enhancement over the H4, is the UTXs ratcheting gland back nut, which prevents backspin once the nut is tightened. The amount and characteristics of materials used to make the UTX have resulted in a more efficient and optimized design. By using gland nuts, environmental gaskets, wire-retention collets, and contacts that accept multiple wire gauges, part count goes down and cost-savings goes up. AISTs UTX connector is the ideal choice for all PV modules and installations around the world.
