High-current spring contacts for demanding contacting applications
Due to the increasing demand for high-current applications across various industries, including electromobility, we have intensively focused on this field. As a result, we are now able to present our innovations in the area of high-current spring contact pins:
FK-891: Up to 160 Amps Thanks to Active Air Cooling
Our innovation: active cooling! And precisely where the critical temperatures occur – inside the high-current spring contact pin.
Our high-current spring contact FK-891 has been developed with an optional internal air-cooling feature. When used without cooling, the spring contact pin already achieves a current-carrying capacity of 60 A. For a contact pin with a diameter of only 4.2 mm, this is a remarkable value. When air at a temperature of 20 °C flows through the interior for cooling, the current-carrying capacity of the FK-891 can be increased up to 160 A.
This makes the FK-891 suitable for applications with high thermal requirements.
With our solutions, you will find the right high-current contact.
Screw-In Series
In the Screw-In series, the FK-891 is integrated into a customer-specific assembly. The individual high-current spring contact pins are screwed into a contact block. Optionally, these assemblies can be equipped with a temperature sensor and an insulated contact pin, known as a sense contact. The maximum current load depends on the load cycle and the number of high-current spring contact pins used.
In addition, the design of the FK-891 allows the entire contact head, including the high-current spring contact, to be temperature-controlled. This enables the contact unit to carry even higher currents.
Perma-Flow Series
It is optionally possible to implement cooling within the cover. This ensures optimal airflow and cooling of the contact points between the plunger and the contact block. As a result, a reliable high-current contact is created for demanding test setups. The assemblies can also be equipped with a temperature sensor and insulated sense contact pins for four-wire measurement .
This provides you with precise results for your high-current testing solution.

Typical application areas for high-current spring contact pins
High-current spring contacts are used wherever high currents must be transmitted safely within a limited space. Typical application areas include:
- Electromobility & automotive: contacting of battery spring contacts, BMS, onboard chargers, high-voltage distribution systems.
- Industrial automation & robotics: power supply for drives, I/O modules, busbars.
- Energy & storage technology: UPS systems, inverters, energy storage systems, DC busbars.
- Medical technology & laboratory equipment: power supply for handpieces, docking stations, modules.
- Test & inspection systems: load contacts in test adapters, contacting of power components.
With individually configurable high-current spring contacts, you can realize robust contacting solutions for reliable connections in demanding power applications, including on PCBs and in compact assemblies.
