A comparatively typical PRL test adapter. The only unusual feature here is the cut-out on the front for a large plug that is on the test specimen.

Test adapter with touch protection
An advantage of this design is the accessibility of the board from above when clamped. Nevertheless, protection against accidental contact is also possible if this is necessary due to high voltages, for example.

Individual interfaces
Protection against accidental contact was also necessary here, as well as an industrial plug that is permissible for mains voltages.

Labeling of the needles
A typical PRL test adapter with labeling of the individual test points, which we can carry out on request. It is subsequently engraved into the needle bed by a laser.

High power transmission
Like our other designs, the mechanics of the PRL ensure excellent power transmission. Hundreds of test needles can be pressed with one hand movement without much resistance.

Contacting of plugs
In this case, a connector on the circuit board had to be contacted with a very fine pitch. This was not possible with test needles. Therefore, a circuit board with the matching mating connector was designed.

For thin boards…
In this example, a very thin circuit board with many needles had to be contacted. At the same time, an electromagnet had to be positioned directly above it when clamped, which made it difficult to hold it down from above. A mushroom-shaped geometry pops through a hole in the board and spreads out before the pins make contact. in order to also hold down the board in the middle. This is a good example of a combination of high-precision parts made using the Material Jetting (MJP) process and more flexible parts made using Selective Laser Sintering (SLS).

Display or control elements
These are very simple PRL test adapters that have been expanded to include operating and switching elements.
