Hermetic Micro-D Connectors (.050″ Contact Pitch)

PA&E’s hermetic family of hermetic Micro-D connectors  is compatible with lightweight materials such as aluminum and titanium, as well as conventional iron/nickel alloys. These MIL-PRF-83513 compliant DC connectors are designed for use in military, space, and commercial applications where environmental conditions require an extremely rugged and reliable hermetic seal. The unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex,® allow PA&E to manufacture this part with a 304L stainless steel shell and gold-plated beryllium-copper contacts for excellent electrical performance and environmental characteristics. These hermetic connectors can be produced for both laser-weld and solder-in applications.

PA&E also offers a non-magnetic hermetic Micro-D connectors for use in harsh environments where superior hermetic integrity and non-magnetic characteristics are crucial to a component’s design. The connector’s shell is comprised of titanium and Inconel because this metal combination delivers the strength, expansion coefficients and low magnetic permeability required. These metals are joined using PA&E’s unique  explosive metal bonding processes. Pin material options include Inconel, molybdenum or titanium.

Al Hermetic Micro-D
Direct Seal Aluminum Micro-D with BeCu Pins.

For applications where weight is a key consideration, PA&E now manufactures an aluminum Micro-D connector that’s approximately 67% lighter than stainless steel alternatives. The aluminum Micro-D connectors have an operating temperature range of -55°C to +125°C and uses PA&E’s industry-proven polycrystalline ceramic-to-metal sealing technology, Kryoflex, to achieve a leak rate of less than or equal to 1×10-5 cc/sec He at one ATM.

HTCC hermetic micro-d with htcc interface
PA&E’s HTCC Micro-D.

PA&E’s hermetic Micro-D  connectors leverage High Temperature Co-Fired Ceramic (HTCC) technology. PA&E’s newest Micro-D connector’s external interface resembles a standard rectangular connector, with rows of sockets providing an electrical connection. In this new, patent-pending design, however, the external sockets are mated to a specially engineered HTCC board (that integrates metalized circuit patterns), rather than traditional pins. This approach can save space and reduce wire-bonding complexity while still maintaining  PA&E’s high standards for harsh-environment reliability and electrical performance. All PA&E hermetic Micro-D connectors are manufactured to exceed the requirements of MIL-PRF-83513.

hermetic mini-micro-d
PA&E’s Mini-Micro-D Saves Space.

PA&E’s Mini-Micro-D connectors are designed for space, airborne, down-hole oil and any other hermetic applications where reducing size and weight are priorities. They have a 27% lower profile than standard Micro-D connectors are designed to be laser welded into aluminum, titanium or kovar housings. These new connectors are MIL-PRF-83513/7 interface compliant and mate with connectors manufactured to MIL-PRF-83513/8.
