E The figure in ( ) for L dimension are applicable for EHSJF □ M/EHSJFE □ M only. E 1MR/2MR are sequential numbering designation. In the case of bulk order of two or more ejector pins with the same size, the sequential numbering engraving is performed. E In case of 1MR, "0" is next to "9" while "A" is next to "Z". E In case of 2MR, the 1st digit is sequential, and if next to "9" or "Z", it starts from "0" or "A" while the 2nd digit is increased by one. X In case of 1MR/2MR, other engraving characters cannot be used for designation.
