High-Current Test Probes
High-current test probes are used when higher currents are involved. Thanks to their compact design, these series are available for centers of 2.54 mm to 5.0 mm with a large number of different tip styles.
Alternatively, all series are available in a threaded type which ensures an excellent fit in the receptacle. Based on PTR’s standard sizes, the high-current types are fitted with a split plunger. During contacting, both parts of the plunger are pressed against each other and, as a result, against the barrel wall. The resulting increased contact with the barrel wall and the overall greater contact surface mean that the test probe can be subjected to higher currents, depending on the series, of 16 A to 100 A.
