High current contacts

We often hear the question: at what current load do you call a contact a high-current-contact?

The answer is simple yet difficult:
For most applications in the normal in-circuit test, a current rating of 3 amps is completely sufficient. So a pin for 5 amps would be already seen as a high current contact. A user from the energy sector is as laugh - here we are often talking of several hundred amps. Everything is relative .... so is this in our section of high current probes.

Therefor in this section, you will find contact probes for both: First we'll present you our range of ICT probes with a higher current load capacity. In the bottom table, you'll find the "real" high current contacts, having a current load capacity of up to 220 Amps.
