For high current applications spring contact probes need to be designed in a special way with very low internal resistances. Especially too high temperatures of the probes or of single components of the probes need to be avoided and the electrical contact to the DUT needs to be optimized. The application range for high current probes is very large. These probes are used in test fixtures, wire harness test modules or in special test setups like e.g. in the field of charging and discharging processes in battery production.
Connection Options for F822 / F832
The Kelvin probe can be mounted either in a simple mounting receptacle or in the Feinmetall combination receptacle with SSMB connection. With the simple mounting receptacle, the connection is made at the receptacle and at the sense pin. Alternatively, the sense pin can also be connected with a connection element.
Using the combi receptacle and the corresponding SSMB connector, no further soldering of connection cables is required.
Advantages of the combi receptacle:
- Solderless replacement of the Kelvin probe
- Easy mounting
- Simple connection of the cables
- Connector offers a defined measuring path with fixed parameters
Position Sensor System
The position sensor system is a modular designed contact probe with a small integrated potentiometer. In addition to realizing an electrical contact to the DUT it allows an exact measurement of the travel of the plunger. This can be useful whenever exact, quantitative and documentable measuring results are required, e.g. for testing connectors or housings in the automotive industry, for the evaluation of injection molded parts or for testing the bending of PCBs.
