Brief Introduction of super pin:
Super pin contacts is a typical miniature connector contacts, the minimum diameter is 0.254mm (0.01”).
Super pin contacts is an advanced and high performace solderless compression connector technology thatcan be repeated disassembly and maintenance, can keep the best connection of the electric current and microwave in the vibration environment.
Super pin contacts with high speed signal transmission, long service life, better adaptability etc. high performance and are widely applied in the fields of both military and industry.
High signal speed capability enabling frequencies greater than 40 GHz.

Application of Super pin contacts:
Super pin contacts can be widely used in weapons, satellite, missiles, space probe, aircraft, supercomputer, vacuum system, product testing system, IC(integrated circuit), unmanned aircraft system, UAS(Unmanned Aerospace Surveillance), jet fighter, radar array, crash-test, RF and high signal transmission etc.
