By using a standard type spanner wrench, polarization sockets can be rotated to desired position. For parts supplied d

11、irectly to the government, polarization will be in the 1-1 position. For other polarization positions, see connector polarization guide configuration A (see marking, note 13d). For direct government acquisition a tool is supplied in the unit package for polarization socket adjustment. 8. Contact and

12、 terminal designations: Contacts and terminals shall be designated on the insulator using letters in the location shown on figure 1. 9. Tolerance shall be .010 (0.25 mm) unless otherwise specified. 10. For direct government acquisition crimp contacts M28731/35-0001 (see table I) are furnished in a p

13、lastic bag in each unit package (see marking, note 13a). 11. For direct government acquisition wrappost contacts are M28731/36-0001 (see table I) and are factory installed in connector body (see marking, note 13a). 12. Marking: a. Connectors supplied directly to the government shall be marked with t

14、he military Part or Identifying Number (PIN) (see table I). Example: M28731/32-0001. b. Connectors supplied with contacts to government end users shall be marked with the military PIN (see table I). Example: M28731/31-0001. c. Connectors supplied without contacts to government end users shall be mar

15、ked as follows: Example: M28731/31E (screw type or socket type from table I). The user shall complete the remaining portion of the military PIN as shown in table I based upon contact type he assembles. Example: M28731/32E-0004. d. Polarization position marking is not required unless otherwise specif

16、ied. When required, polarization marking shall be in accordance with the connector polarization guide (see configuration B). The marking shall appear following the PIN. 13. Applicable contact insertion and removal tools: Insertion - MIL-I-81969/5-01 Removal - MIL-I-81969/4-02 14. Rectangular shields
