Sliding probes are specifically designed to inspect rows of fasteners. They operate in reflection mode (driver/pickup coils) and are used to find surface and near-surface flaws. Sliding probes are available in two different types:
The fixed versions typically include the Fischer/LEMO Triax connector and their underside is relieved to enable the probe to easily slide over raised fastener heads. | ![]() |
