Connectors shall be of the design, construction, and physical dimensions specified on the applicable
product drawing, and as shown in Figures 1 and 2. The plug uses FCI's Gold Dot MINI PV and MINI
LATCH housing and incorporates a shield can to provide a ground path from the cable shield thru
the header ground terminals to the PCB.
6.0 ELECTRICAL CHARACTERISTICS
6.1 Low Level Contact Resistance
The low level contact resistance shall not exceed 25 milliohms (35 milliohms after environmental
exposure)(based on 26 AWG wire per Figure 4) when measured in accordance with MIL-STD-
1344A, Method 3002.1. The following details shall apply:
(a) Method of Connection - Attach current and voltage leads where shown in Figure 4.
(b) Test Voltage - 20 millivolts DC max open circuit.
(c) Test Current - Not to exceed 100 milliamps.
6.2 Ground Terminal to Shield Contact Resistance
The ground terminal to shield contact resistance shall not exceed 8 milliohms (14 milliohms after
environmental exposure) when measured in accordance with MIL-STD-1344A, Method 3002.1. The
following details shall apply:
(a) Method of Connection - Attach current and voltage leads where shown in Figure 4.
(b) Test Voltage - 20 millivolts DC max open circuit.
(c) Test Current - Not to exceed 100 milliamps.
6.3 Shielding System Performance
Shielding system performance varies with frequency, and should be evaluated for each special
application. The following table is representative of typical responses when measured using a
swept frequency response method as described in BUS-03-107. The response from the cable is
measured with a current probe sensor with the spectrum analyzer set to the "maximum hold"
function. The difference in response from an unshielded reference cable assembly and the shielded
cable under test is defined as the shielding performance of the connector.

Figure 2 shows the physical appearance of the test samples. The cable is described as 6
conductors with an inner aluminized mylar shield, 95% coverage, and an outer tinned copper braid
shield with 95% coverage, and one 26 AWG (7/34) tinned copper drain wire.
The table results represent the difference between three standard LATCH-N-LOK shield termination
methods and a similar assembly with no electrical connection between the cable shield and
connector shield can.
