D38999 II Series connectors，MS27508E18B35PCB electric connectors

MS27508E18B35PCB​:

Shell components are impact extruded or machined bar stock aluminum. Standard plating on shell components is cadmium over nickel. Many finishes are optional . Hermetic seal receptacles are available in carbon steel or stainless steel shells. Dependable 5 key/keyway polarization with bayonet lock coupling is incorporated to aid and assure positive mating. Insert material is a rigid dielectric with excellent electrical characteristics, providing durable protection for molded-in solder type contacts. Contrasting letter
or number designations are used on insert faces. A fluorinated silicone interfacial seal wafer is featured on the mating face of “crimp type pin” inserts. This assures complete electrical isolation of pins when connector halves are mated. In addition, a main joint gasket is installed in the receptacle for
moisture sealing between connector halves. Both features are also available for hermetic receptacles.

Our company is located in Nanjing city, Jiangsu province, which is specializing in the production of various specifications in our country and the key enterprise of electric connectors, passed the DJB9001A - 2001 military quality system and ISO9001-2008 quality system certification. Now we have hundreds of military enterprise, military universities, research institutions, the national key research institute of supporting units. Company cooperation of countries all over the world, such as South Korea, Japan, Vietnam, Iran, Pakistan, Turkey, the United States, Mexico and Russia. Our company sets product technology research center, has skilled workers, precision machining equipment, modern testing instruments and perfect testing means.

At 1995, we were founded.

At 1996, we started to produced the Y2 connector. The design of Y2 connector was from Russian, and in Russian it is high-performance connector only for using in military. But in China, we produced it for using in civil device.

At 1997, we won the ISO9000 quality system certification and tried to make the Y 2 connector for Chinese Military according to Chinese Military Standard.

At 1998, we began to prepare for Chinese Military auditing and start to research Chinese Military Standard Connector Y3, Y4 and Y11 series.

At 1999, we won the first certificate from Military Product Quality System Certification Committee and form ally supplied our Y2, Y3, Y4 and Y11 series connector to Chinese Military. A t the same time, we started to research Y17, Y18 connector.

In 2000-2003, we researched and developed all the Chinese Military Standard circular connector and supplied large quantity to Chinese Military including Y27, Y50, XC ,YXK , YGD ,YM , etc. Meantime we introduced Russian Military Connector PbM4 series into Chinese Military.

At 2004, we won the second certificate from Military Product Quality System Certification Committee and started to build our new factory. In the same year, we started to research rectangle connector according to Chinese Military Standard and circular connector MIL-C-26482 series I, II & MIL-DTL-38999 I, II, III, IV series according to USA Military Standard.

In 2005-2007, we had supplied all Chinese Military Connector including circular connector and rectangle connector with high quality and also we started to supply MIL-C-26482 series and MIL-D TL-38999 series to oversea for econom ical price.

At 2008, we started to participate in establishing Chinese Military Connector Standard. A lso we built a department to design the connector according to requirement from customer, especially oversea.

In 2009---,we have been one of the most professional manufacturer of connector in China and our long-term oversea customers have been more than 300 including HP , GE , Siemens, Panasonic, Souriau, ABB, etc.
