ecomate® RSSM IP69K Circular Metal Connectors

Amphenol Sine Systems ecomate® Rugged Superior Seal Metal (RSSM) Circular Metal Connectors are available with numerous insert arrangements and match all the specifications of the ecomate RM series, with the addition of superior seals (+125°C). The seals increase the IP ratings to IP67/69K (in mated condition). The RSSM plugs can only mate with ecomate RSSM receptacles to ensure an IP69K rating. Contacts are available in machined or PCB (loose piece/bagged) or stamped and formed (reels) options. Amphenol Sine Systems RSSM connectors can be shared with the ecomate Aquarius™, Aquarius™ Fathom Lock, and RM series. The connectors are ideal in circular, rugged, superior seal, and metal connector industrial applications. The series is available in 8 shell sizes and 28 insert arrangements.
