Sung Jin C&T is a leading connector company specialising in the design and manufacture of MIL-Spec and Commercial circular connectors and military head sets, hand sets, neck microphones, wireless intercom and cable harnesses.

Serving such industries as Defence, Medical, Communication and Transportation, Sungjin's goal has always been to exceed customer's expectations by assuring world class product, on time and with competitive prices. In concert with Korean household names like LG and Samsung, Sungjin are successfully challenging the dominance of Japanese companies, e.g. Hirose and JAE by delivering products that are as aesthetic as they are reliable and functional. In2Connect's mission is also to provide the shortest lead-times, lowest prices, and the highest quality to our customers whilst ensuring the best customer service ~ and we pride ourselves in achieving this.

Sungjin's modern factories hold ISO 9001, UL Certification and have been awarded prestigious Government Export awards. They are qualified by the Korea Defense Agency and rated A+ Grade by KIBO. The Kibo Technology Fund, headquartered in Pusan, South Korea, provides technology guarantees and assessments to manufacturing companies.

Sungjin's capabilities include in-house machining, high speed assembly and complex testing for both connectors and harnesses. In2Connect are proud to support Sungjin in the European marketplace.

In2Connect stocks the most commonly requested MIL-C products. We also build Cable and Connector Assemblies. We have consistently provided and supported companies both domestically and internationally, and we look forward to serving you!

RoHS Compliant Being good to the environment is important to both us and our customers. That's why as well as the ubiquitous drab olive, Sungjin can also provide RoHS compliant parts across many of its product ranges. RoHS compliant MIL-C shells now utilise Black Trivalent Chromium in place of any Hexavalent Chromium previously used in protective coatings. RoHS compliance is independently tested/certified by the Korea Environment & Merchandise Testing Institute.
