Designation method NHC–6 NHC–23 NHC–A90 E Applicable to flange diameter H ≧ 2 X Not available with SKC/MC X In some cases, the processing is not possible if the back of the flange cannot accommodate the character size of 1.8 in length x 1.8 of width. Automatic sequential numbering on the head Automatically adds a sequential number on the head of each ejector pin when two or more pieces of identical size are ordered. Available characters Same as NHC (see above) Range of designation Same as NHC (see above) Designation method When 3 pieces are ordered with NHN–1, a sequential number starting from 1 is added at the back part of the head of each piece. When 10 pieces are ordered with NHN–A15, a sequential number starting from A15 through A24 is added at the back part of the head of each piece. E Only available when two or more pieces of identical size are ordered. E Applicable to flange diameter H ≧ 2 X Not available with SKC/MC X In some cases, the processing is not possible if the back side of the head cannot accommodate the size of 1.8 long X 1.8 wide X no. of characters.
