Circular Connectors

RoHS compliant waterproof connectors

Rugged and waterproof, yet kinder to the environment – these connectors are fully RoHS compliant yet still meet all the electrical and mechanical performance requirements of MIL-DTL-5015 (was MIL-C-5015).

About Circular Connectors

  • Exceeds IP67 sealing requirements – water immersion of 1.8m for 48 hours
  • 13 Amps per contact
  • Rugged, durable – withstands multiple mating cycles and rated to 10G vibration, 50G shock
  • Stocked in depth across the Harwin Authorized Distributor network
  • All contacts are solder cup for cable connection
  • 3 body styles – Cable connector with rotating threaded ring, mating Panel mounting with external thread,  and mating Cable connector with external thread

As a connector range designed to meet the performance of MIL-DTL-5015, but with the added improvement of RoHS compliance, these connectors are ideally suited for COTS (Commercial Off-The-Shelf) programs.
