21、r frequency control and selection devices In order to achieve a uniform presentation of outline drawings for frequency control and selection devices, the following shall be considered. a) An outline drawing shall show all dimensional and geometrical characteristics of an enclosure necessary to ensur
22、e mechanical interchangeability with all other enclosures of the same outline. Enlarged and detailed view may be used, if necessary. b) The outline drawing shall consist of three parts: 1) A drawing with dimensional symbols (capital letter) as shown in Figure 1 with applicable footnotes, if necessar
23、y. 2) A tabular listing relating to the drawing symbol to the actual dimensions. Where possible, this shall be shown on the same page as the drawing. 3) An “actual-size“ sketch (scale 1:1). c) The outline drawing shall be executed in the third-angle projection. d) The function and identification of
24、the lead connections (termination) shall be determined by agreement between the supplier and user. They shall not be defined on the outline drawing. e) Descriptive footnotes may be used at the bottom of/ or adjacent to, the drawing with proper reference to the body of the drawing. f) All dimensions
25、shall be in millimeters. g) 0utline dimensions A, B, C, D and E shall be listed with maximum values only. h) If there are plural identical enclosures with different height (C), C shall be expressed with a suffix number such as C1, C2, etc. The following letter and number after the basic type number
26、(four digits) indicate the enclosure height and lead length. The identity references are given in the table in the sheet. i) Lead (termination) cross-sectional dimensions shall be listed with minimum and maximum values. If applicable, nominal dimensions may be added. j) The spacing of the leads (ter
27、mination) symbol H shall be listed with minimum, nominal and maximum dimensions.
