Beschreibung des Produkts
The Coaxial High Current Probe HC074B07G23 (item number 1012660) is designed for safe transmission of high electrical currents in test and contacting applications. HC074B07G23 focuses on current capacity and low transition losses, as required in battery testing, formation and other e-mobility applications. For HC074B07G23, contact resistance, contact force and thermal behavior must be considered together because they influence voltage drop and temperature rise at the contact point. The intended application area for HC074B07G23 includes battery contacting. The probe is rated for 250 A continuous current with a typical contact resistance of 1 mΩ. Spring force is 2300 cN at a nominal travel of 4 mm.
