High current test probes are used in several industries and applications with high currents, such as testing, function tests, signal transmission, power supply in production, as well as assembled contact elements.
Another field of application is precise measurement, which requires test probes with very low internal resistance, so-called low Ohm test probes.
For secure transmission of high currents the plungers in INGUN high current test probes consist of two parts. During the stroke movement the plunger parts are deflected away from each other in a radial direction. In doing so, the plunger parts press against the barrel and the transfer resistance (Ri) is reduced. This principle allows the transmission of high currents with limited warming. The power loss, which causes warming, is calculated using the formula PV=Ri*I2.
Depending on the application and the related test demands, INGUN offers various high current test probes (HSS):
