Souriau PA&E recently introduced its Mini Micro-D Connector (part no. 94594), a new hermetic connector option aimed at design engineers who need to reduce component size and weight without compromising electrical performance. According to the company, the Mini-Micro-D connectors are designed for space, airborne, down-hole oil, and any other hermetic applications where reducing size and weight are priorities. Souriau PA&E says the new connectors have a 27% lower profile than standard Micro-D connectors and are designed to be laser welded into aluminum, titanium, or kovar housings.
The connectors are MIL-PRF-83513/7 interface compliant and mate with connectors manufactured to MIL-PRF-83513/8. Souriau PA&E says the Mini Micro-D connectors can be configured with 9, 15, 21, 25, 31, and 37 pin counts. The connector's beryllium-copper pins support 600 VAC and 3 amps per pin. According to the company, each pin is hermetically sealed with Souriau PA&E’s polycrystalline ceramic material, Kryoflex, to provide greater than 5,000 megohms of insulation resistance at 500 VDC and exhibit no evidence of dielectric withstanding voltage breakdown when tested in accordance with MIL-STD-1344, Method 3003.
The hermetic Micro-D connectors have a leak rate of less than 1X10-9 cc/second of helium at one atmospheric differential pressure and will operate reliably at temperatures from -65ºC to 200ºC. CAD models and detailed drawings for Souriau PA&E hermetic Mini Micro-D connectors are available at the company's website.
