We've achieved a breakthrough with our test chamber feed-throughs.

When load and signal lines need to be inserted into test chambers, two challenges often arise: firstly, the temperature and humidity conditions make the expensive cables and contacts suffer massively. Secondly, the breach in the chamber wall means that the test chamber is no longer reliably sealed, which impairs the validity of the measured values, wastes energy and also poses a safety risk.

The power and signal feed-throughs we have developed in-house allow cables to be connected to the outside and inside of the wall. This way, they represent a loss-free and safe transfer point between the test bench and the OUT. At the same time, they tightly seal the breach in the wall of the test chamber and make sure that the overall system is reliably capped.

Reliably sealed test chambers. Individually configurable.

Our DFP and DFS feed-throughs have been specially designed for use on battery test benches and we have been testing them in our own test facility for many years. Consequently, our products meet the special requirements of this application. That said, however, they also deliver excellent results in other scenarios.

Our heat- and cold-resistant feed-throughs can be configured with a variety of different plug-in types and we manufacture them for different test chamber wall thicknesses and diameters – exactly according to your individual specifications.
