38999 Style Hermetic Connectors

38999 connector


Our 38999 circular DC connectors combines Kryoflex® ceramic-to-metal sealing technology with ultra light-weight materials to create truly hermetic connectors. Using the light-weight aluminum housings will create a connector that is up to 60% lighter than stainless steel without sacrificing reliability. These DC connectors can be produced for both laser-weld and solder-in applications. Our hermetically-sealed 38999 mateable circular connectors are fully compliant with the interface requirements of MIL-DTL-38999. PA&E now also offers this style of connector with integrated EMI filters. These filtered connectors are custom configured to meet a range of EMI filter performance parameters. Connectors using C- and L-section filters can support 5-15 amps, working voltage of 50- 400 VDC with a minimum insertion loss of between 2 and 70dB, depending on configuration. Connectors using Pi-section filters support 10 amps and a working voltage of 50-300 VDC with a minimum insertion loss of between 2 and 70dB, depending on configuration.

Note: PA&E 38999 mateable connectors are not QPL (Qualified Parts List).
