1. Datum plane H is located at bottom of lead and is coincident with
the lead where the lead exits the plastic body at the bottom of the
parting line.
2. Datums AB and D to be determined at datum plane H.
3. Dimensions S and V to be determined at seating plane C.
4. Dimensions A and B do not include mould protrusion. Allowable
mould protrusion is 0.25mm per side. Dimensions A and B do
include mould mismatch and are determined at datum plane H.
5. Dimension D does not include dambar protrusion. Allowable
dambar protrusion shall be 0.08 total in excess of the D dimension
at maximum material condition. Dambar cannot be located on the
lower radius or the foot.
6. Dimensions and tolerancing per ANSI Y 14.5M, 1982.
7. All dimensions in mm.
