Due to the integrated spring loaded plungers, this block offers a low resistance contact even if the contact surface is uneven or inclined. The maximum current depends on the allowed temperature. The connection of the plunger should be realized by a flexible wire (recommended 16,0 mm²) with sufficient space for the movement.
For assembly these test heads will be directly screwed into the conducting material. The adaptor for the test head has to be designed for contacting the thread as well as the rear side of the test head plate. For the electrical connection we recommend standard cable eyes.
