Description of MIL-DTL-83513 connector

By its very design, the Micro-D type connector system meets all the requirements of robustness, durability, low contact resistance, high current, dielectric strength, shock, and vibration. With 1.27 mm (.050″) contact spacing, micro d subminiature, half the size of D type connectors (D series connectors), represent an excellent solution for saving both space and weight. In addition to a complete range of micro d subminiature connectors to 83513 d sub vs micro d, Sunkye also offers Micro-D PCB connectors and cable assemblies in both metal and plastic bodied versions. With its many possible configurations, the technology of micro electrical connectors is perfectly suited to a multitude of systems where weight, miniaturization or signal transmission integrity is paramount: applications benefiting from this technology include everything from missiles and their guidance systems, through oil well drilling tools to medical devices, satellites, and scientific research. For very specific applications such as medical MRI scanners or low magnetic field detection systems, Sunkye has developed a range of non-magnetic connectors using new materials and surface treatments, avoiding ferromagnetic materials. Hermetic micro d connectors are also offered for applications where an enclosure needs to be fully sealed from the outside world.

By the unique design and performance, Sunkye micro d connectors equipped with twist pin contact is enabled to meet the most severe requirements, often significantly more so than stipulated in the mil 83513 and MIL-DTL-32139 standards. The male micro D contact is composed of 10 strands of copper alloy and beryllium-copper twisted together, which is welded then bumped. A high number of electrical contact points are permanently assured while retaining flexibility and ease of insertion/ extraction, because during insertion into the turned female contact the 10 sprung strands are compressed. To keep insertion and retention performance of the twist pin and socket mated pair, the bulged point will be compressed inside the socket during insertion. Meanwhile, the exit of socket contact chamfer and twist pin hemispherical radius ensures adequate insertion even in case of misalignment.

Range of mil dtl 83513 contacts which is covered by the mil dtl 83513 standard is ideally suited to equipment and applications where weight, miniaturization and long term performance are required, so in these aspects it is a model recommended by micro d connectors manufacturers. It is available: In 10 contact arrangements (9 to 100 contacts) for rectangular Micro-D connectors

 What is PEEK?

Polyether ether ketone    (PEEK) is a colorless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications.

PEEK is a thermoplastic semicrystalline with excellent mechanical and chemical resistance properties that are retained to high temperatures. PEEK has a glass transition temperature of around 143 °C (289 °F) and melts around 343 °C (662 °F).  That’s why PEEK seals and manifolds are commonly used in fluid applications. PEEK also performs well in applications where continuous high temperatures (up to 500 °F/260 °C) are common.  It has high resistance to halogen, strong bronsted and lewis acids, thermal degradation,biodegradation, Air leak: helium leak test≤1×10 -3 Pa.cm 3 /s

PEEK melts at a relatively high temperature (343 °C / 649.4 °F) compared to most other thermoplastics. In the range of its melting temperature, it can be processed using injection molding or extrusion methods. It is technically feasible to process granular PEEK into filament form and 3D printing parts from the filament material using fused deposition modeling – FDM (or fused filament fabrication – FFF) technology. PEEK filaments have been demonstrated for producing medical devices up to class IIa.

In its solid state PEEK is readily Machinable, for example, by (CNC) milling machines and is commonly used to produce high-quality plastic parts that are thermostable and both electrically and thermally insulating. Filled grades (30% Glass filled) of PEEK can also be CNC machined, but special care must be taken to properly manage stresses in the material.

PEEK is considered a high-performance polymer, that is to say, its high price restricts its use to the most demanding applications only. Because of its robustness, PEEK is used to fabricate items used in demanding applications, including bearings, piston parts, pumps, High-performance liquid chromatography columns, compressor plate valves, and electrical cable insulation. It is one of the few plastics compatible with ultra-high vacuum applications.

Beware of the difference of PEEK & PEK

PEEK is Polyether ether keton & PEK is Polyether keton, both are very strong mechanical and chemical resistance properties but PEEk has one more molecule that means the physical performance more stability.

The Usage of PEEK Connector

PEEK connector, we also call it PEEK sealing terminal or HTHP connector, just as its name implies which the connector is made from PEEK material combining with metal contact and using glass sintered technology sealing PEEK material & contact so it has perfect air leakage performance. In wellhead, gate valve requires to PEEK terminal for sealing, or tubing head spool for connect gauge or control line of the outlet of the wellhead, and using on adapter spool for hydraulic control line terminated(C/L), electrical cable fit.The working environment of oil gas petrochemical industry is always harsh, dirty, and with high pressure, extreme temperature, chemical corrosion, low PH erosion, and various different kinds of gas. sealed connectors which can withstand physical performance with Pressure in 30,000PSI /207Mpa and the extreme temperature in 300℃, can perfectly satisfy the working needs for the special area and provide high-performance solutions as oil and gas connectors.
