2、cation covers the detail requirements for ultra high density connectors, surface mounted on daughter board modules or fixed backplanes. The connector contacts are densely packed with .050 inch (1.27 mm) spacing between contact centers in the same row. These connectors are intended for use in assembl

3、ies requiring very densely packaged electronic components, and are commonly used in digital applications. 1.2 Part or Identifying Number (PIN). The PIN consists of the letter M (see 3.7) the basic specification number, a forward slash, a specification sheet number, a dash, a letter for the insulator

4、 material, a letter for the EMI/RFI shield, two numbers for the termination tail length or termination tail separation, a letter for the keying pin, a letter for contact sealing (when applicable), a letter for termination tail finish (when applicable), and a letter for space class (when applicable)

5、(see 3.1) shown in the following example: Space class (1.2.7) M 32234/ 01- A E 16 DK S T S Contact sealing (see1.2.5) Termination tail finish (1.2.6) Keying pin/bushing (see 1.2.4) Termination tail length (see 1.2.3) EMI/RFI shield (see 1.2.2) Insulator material (see 1.2.1) Basic specification numbe

9、Each specification sheet will provide a chart which will identify available termination types and an associated code letter to include in the PIN. 1.2.4 Keying pin/bushing. The PIN will utilize two characters to identify the shape of the keying pin or bushing. Each specification sheet will provide a

10、 chart, which will identify available keying types and an associated code letter. When keying pins/bushings are supplied with the connector they will be shipped loose. 1.2.5 Contact sealing. Contact sealing will be identified as follows: S - Connectors are sealed to prevent entry of cleaning fluids

11、or conformal coatings into the contact area from the termination side of the connector. N - No sealing is provided. 1.2.6 Termination tail finish. Termination plating will be identified as follows: T - Tin/lead G - Gold 1.2.7 Space class. The PIN will utilize a single character to identify space cla

12、ss connectors that have passed thermal vacuum outgassing testing. Blank - Blank for non-space applications. S - For space class. 2. APPLICABLE DOCUMENTS 2.1 General.
