5、 These connectors mate with connectors specified in MIL-DTL-55302/169 and MIL-DTL-55302/170 and are primarily for use with single-sided, double-sided, or multilayered printed wiring boards. 5. The polarization feature, utilizing four M55302/78-02 polarizing keys which are not supplied with the conne
6、ctor, will provide 256 unique polarizing positions. 6. For dimensions A through K, see table I. 7. Coupling/mounting bushings are not supplied with the connector. See M55302/172-05. 8. Contact rows are identified by molded letters on the front and rear face. Numbers indicating every fifth contact pe
7、r row appear on rear face, except for arrangements consisting of 10 contacts per row which lack numerals. Up to 9 contact locations at the high numeral end of the contact row will not be identified. 9. Perfect form at MMC not required. Dimension for user installation purposes only. 10. Part or Ident

Contacts: Each contact shall contain 7 brush wires with a tolerance limit of 1. Each brush wire diameter shall be .007
11、3 to .0085 inch (0.185 mm to 0.216 mm). Material: Body: Glass filled thermoplastic molding material in accordance with ASTM D5948, type GPT-15F. Contacts: In accordance with MIL-DTL-55302, ASTM B187/B187M or ASTM B272. Plating: The contact termination plating shall be specified in table III. Brush w
12、ire plating shall be gold in accordance with ASTM B488, type II, code C, class 1.27 over nickel in accordance with MIL-DTL-38999, Appendix A. Cut ends or brush wires need not be plated. Contact identification: See figure 1 (note 8) and figure 2. Oversized pin exclusion: Not applicable. Contact engag
13、ement and separation forces: Not applicable, see mating and unmating. Mating and unmating: The maximum mating and unmating force shall be 1.5 ounces times the total number of contacts. Contact current rating: The connector may have any combination of current flow and ambient temperature provided the
14、 contact or connector temperature does not exceed 125C. The test current shall be 5 amperes for individually connected contacts and 3 amperes for series wired contacts. Contact resistance: The average resistance of all contact pairs measured on row A contacts shall not exceed 0.016 ohm, and no indiv
15、idual pair shall have a resistance exceeding 0.020 ohm. To allow for increased terminal lengths, add 0.001 ohm for each contact row beyond row A. The point of measurement shall be the point of terminal exit from the printed wiring board. Contact retention: 3 pounds per contact minimum when the force
16、 is applied in the forward direction. The displacement shall not exceed 0.005 (0.13 mm). The displacement shall be recorded after a 1 pound preload is used to determine the zero displacement reference. Dielectric withstanding voltage: Sea level: 1,300 volts rms, 60 Hz, ac. High altitude: 325 volts r
17、ms, 60 Hz, ac. Extended contact life: Connector shall meet the performance requirements of MIL-DTL-55302, contact life, when subjected to 20,000 insertion and withdrawal cycles during qualification inspection. Insert arrangement: See figure 2. Provided by IHSNot for ResaleNo reproduction or networki
