Performance and Test Description
Product is designed to meet electrical, mechanical and environmental performance requirements
specified in Figure 1. Unless otherwise specified, all tests shall be performed at ambient environmental
conditions per Test Specification 109-1.
Test Requirements and Procedures Summary
Test Description
Voltage: 100 volts AC
Current: The maximum current at 30° C temperature r ise shall not exceed values listed for specific
contact positions energized as shown in Figure 1, reference EIA 700A0AE and Figures 5A and 5B.
Temperature: -55 to 105° C
NOTE
Position
Current levels are based on steady state conditions. When the connector is used in “hot
plug” applications, current spikes shall be minimized using a current limiting device.
