Kelvin screw

Kelvin screw M12, M14 and M16

Two such Kelvin screws are needed for connecting with the 4-wire method to a test object for micro-ohm measurement where Kelvin clamps cannot be used (e.g. because of a contact cluster). The Kelvin screws are then screwed into the threads of the test object after the contacts are unscrewed. It offers two electrically insulated connection points to the test object. One is a 6mm banana jack (for currents up to 100 A) and one is a 4 mm banana jack for voltage sensing. The outside diameter is 35 mm (1.4 in), total length of the Kelvin screw is approximately 11 cm (4.3 in).
