(Note 1) When 2 or more wires are inserted into terminals for crimping, ensure that the combined total of the wires' cross-sectional area is within the wire conjugation capacity range and is also similar to the terminal nominal.
(Note 2) The calculation method of the L dimension is simply for finding the dimensions of the wire sheath stripping, and is not used to indicate the shape or dimensions after crimping.
(Note 3) For applicable wires at 0.3, use a conductor cross-sectional area close to the terminal nominal. Furthermore, fold back the core wire when crimping thin types such as AWG28.
Also, ensure that the wire stripping dimension complies with the terminal nominal 1.25.
