Tolerances between any two contact centers shall be .004 (0.10 mm). 4. Flatness, squareness, and parallelism shall be within dimensional tolerances. 5. Contact hole
9、 details shall be in accordance with configuration B. 6. Mating connector information: M28731/30-0001 mate with M28731/29-0003 and -0005. M28731/30-0002 mate with M28731/29-0004 and -0006. M28731/30-0003 and -0005 mate with M28731/29-0001. M28731/30-0004 and -0006 mate with M28731/29-0002. 7. Polari
10、zation information: Polarization sockets are provided for indexing to preclude intermixing of adjacent connectors. By using a standard type spanner wrench, polarization sockets can be rotated to desired position. For parts supplied directly to the government, polarization will be in the 1-1 position
11、 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 terminal designation: Contacts and terminals shall be designated on
12、 the insulator using letters in the location shown on figure 1. 9. Tolerance shall be .010 (0.25 mm) unless otherwise specified. 10. Patent notice: Patent No. 3,675,185 owned by Elco Corporation. The government has a royalty-free license under the above patent for the benefit of manufacturers of ite
13、ms called for in this specification, either for the government or for use in equipment to be delivered to the government. 11. For direct government acquisition crimp contacts M28731/35-0001(see table I) are furnished in a plastic bag in each unit package (see marking, note 13a). 12. For direct gover
14、nment acquisition wrappost contacts are M28731/36-0001 (see table I) and are factory installed in a connector body (see marking, note 13a). 13. Marking: a. Connectors supplied directly to the government shall be marked with the military Part or Identifying Number (PIN) (see table I). Example: M28731
15、/30-0001. b. Connectors supplied with contacts to government end users shall be marked with the military PIN (see table I). Example: M28731/30-0001. c. Connectors supplied without contacts to government end users shall be marked as follows: Example: M28731/30E (screw or socket type from table I). Th
16、e user shall complete the remaining portion of the military part number as shown in table I based upon contact type he assembles. Example: M28731/30E-0004. d. Polarization position marking is not required unless otherwise specified. When required polarization marking shall be in accordance with the
17、connector polarization guide (see configuration B). The marking shall appear following the PIN. 14. Applicable contact insertion and removal tools: Insertion - MIL-I-81969/5-01 Removal - MIL-I-81969/4-02 15.
