NOTES:
1. Dimensions are in inches. Unless otherwise specified, tolerances are ± .015 inch for two place (.XX), and
± .005 inch for three place (.XXX) dimensions.
2. Tolerance is ± 0.5 (½) degree on angles.
3. Metric equivalents are given for general information only.
4. Maximum projection from front panel including mounting gaskets (if used).
5. Other forms of terminals, as specified in MIL-PRF-10304, are permitted. The specified minimum length applies
to stud-type terminals only. Terminals shall be equally spaced, from each side of vertical centerline.
