MIL-DTL-3643 Connectors, Coaxial, Radio Frequency, Series Hn, And Associated Fittings, General Specification ForThis specification covers the general requirements for weatherproof, series HN-radio-frequency, coaxial connectors and associated fittings. These connectors have a nominal impedance of 50 ohms, an operating voltage of 1,500 volts root mean square, and a nominal operating frequency range of 0 to 10,000 MHz \(see 6.1 and 6.3\).

MIL-DTL-3643B

4.4.1.5 Interchangeability (applicable only to male terminations) (see 3.3.5). A test gage in accordance

with figure 2 shall be used. When testing connectors in which center contacts are not permanently

assembled, the center section of the test gage shall be removed. When testing connectors in which

center contacts are permanently assembled, the center section of the test gage shall be inserted and held

in the position shown on figure 2. The coupling nut shall then be hand tightened on the gage. Rejection

of male connector is based on binding as the connector is coupled, or protrusion of the center pin during

or after coupling.

NOTES:

1. Total Indicator Reading (T. I. R.) of all diameters = .0003 inch (.008 mm) max.

2. Tolerance of dimensions, unless otherwise specified shall be �.0005 inch (0.013 mm).

3. All dimensions in inches.

4. Material shall be cold-rolled steel in accordance with ASTM A108, and shall be chrome plated.
