EN 3155-004:2007 4 0 Introduction The contacts defined by this standard are derived from those of MIL-C-39029/4 and, intermateable with those of MIL-C-39029/5. They are specified as a 260 C class instead of a 200 C class as detailed in the MIL
12、stan- dard. 1 Scope This standard specifies the required characteristics, tests and tooling applicable to male electrical con- tacts 004, type A, crimp, class T, used in elements of connection according to EN 3155-002. It shall be used together with EN 3155-001. The associated female contacts are de
