Amphenol Heavy-Duty ATHD Series

The Amphenol heavy-duty ATHD series is ideal for rugged, high-vibration applications.

Amphenol Heavy-Duty ATHD Series ConnectorsAmphenol Industrial Products Group now offers a heavy duty connector series for size 8 and size 12 power contacts.  The new ATHD series is a single-pole, rugged, in-line connection system designed to replace splices as well as provide power wherever needed. Using Amphenol’s exclusive Radsok technology, the connector can reach higher amperages than other connectors in its class. 

Ideal for rugged, high-vibration applications found in the heavy equipment and mining markets, these sealed, thermoplastic connectors are field-installable and -repairable, eliminating the need for costly, non-repairable splices. The connection systems also feature clip slots for a variety of harness-mounting solutions.

The size 8 system is rated to 70A continuous with the Radsok terminals and has a contact retention of 156 N. The size 12 system is rated to 35A continuous with the Radsok terminals and has a contact retention of 133 N. The ATHD series is RoHS-compliant and has an IP67 rating. Standard machined and stamped and formed contacts are also offered for both sizes with a variety of platings.  The size 12 system has special stamped and formed contacts that will crimp to 16-gauge cable where less amperage is needed.

Both the size 8 and size 12 power contacts can perform up to 100 mating cycles and have an operating temperature range of -55°C to +125°C. They each have an operating voltage of 1,000VAC and dielectric withstanding voltage of 1,500VAC. Insulation resistance for each connector is 1,000 M Ohm.

Additional styles and custom solutions, including resin for higher temperatures up to 150°C and seals for harsh fluid applications, are available upon request.
