MS3471E w/AMENDMENT 1 NOTES: 1. Dimensions are in inches. Metric equivalents are given for information only. 2. Unless otherwise specified, tolerances are .005 (0.13 mm) for 3 place decimals, .01 (0.3 mm) for 2 place decimals, and 1 for all angles. 3. True position (TP) tolerances specified are in accordance with ASME Y14.5M. 4. Polarizing stripes, color optional. 5. Color bands: 0.070 .031 (1.78 0.79 mm) wide, color blue. Band location must be such that it is visible when mounting. 6. Insert arrangements requiring reduced diameters for raised seal barrier on outer row of contact cavities as indicated. 7. Connector assembly must be used with a backshell. Backshells must be procured separately. See SAE-AS85049 for applicable backshells. FIGURE 1. Receptacle, dimensions and configurations - Continued.

See MIL-DTL-26482, connector intermateability control dimensions (series 1 and series 2) figure for reduced diameter "XX" for contact size 20 only. REQUIREMENTS: Dimensions and configuration: See figure 1 and table I. Connector mating: This connector mates with MS3475 and MS3476. For insert arrangement: See MIL-STD-1669. Connector identification marking shall be in accordance with MIL-DTL-26482. Example: MS3471L----, minimum height does not apply to shell sizes 8, 10 and 12. Class E is cancelled and superseded by class L. Intermateability and rear accessory interchangeability dimensions shall be in accordance with MIL-DTL-26482. This MS sheet supersedes MS3471(Navy), MIL-C-83723/7 and MIL-C-83723/8. 6 Source: http://assist.dla.mil -- Downloaded: 2019-04-19T10:23Z Check the source to verify that this is the current version before use.
