Beschreibung des Produkts
For power-intensive contacting, HCF73355B300G300 (item number 1016561) provides a spring-loaded high-current path within the test setup. HCF73355B300G300 focuses on current capacity and low transition losses, as required in battery testing, formation and other e-mobility applications. For HCF73355B300G300, current capacity, low contact resistance and defined contact force are key to limiting electrical losses and unwanted heating. The design combines a pitch of 4 mm / 157 mil with tip style 55 (Concave stepped (self-cleaning)) and a tip diameter of 3 mm. HCF73355B300G300 operates with 300 cN spring force and 4 mm nominal travel. For HCF73355B300G300, the specified continuous current is 30 A.
