What our customers say

“Direct contact with developers makes collaboration very enjoyable. It is often possible, on the basis of simulation results, to reach agreement on an almost production-ready sample status at an early stage”.

Of increasing importanceNoise-damped solenoids

Noise emission is becoming an increasingly important topic in the interior of vehicles, especially in the wake of electrification of vehicles. Speak to us, and let us find the right solution for your task.

  • Service life: We design the relevant materials and components to achieve a precise fit with your requirements and cost framework.

  • Version forms: Regardless of whether pulling or pushing version, monostable or bistable.

Reliable locking and unlockingLocking solenoids

Ideal for tasks in which mechanical applications need to be released or locked with a direct drive.

  • Noise reduction: As you can see, great emphasis is also placed in these solutions on the noise characteristics of the actuators.
  • Integration: Due to our vertically integrated production operations, it is no problem for us to create complex and inexpensive locking geometries.
  • Types of version: Here too, it is no problem for us to create pulling or pushing versions.

Holding solenoid systems redefinedPermanent solenoids and holding solenoids

We achieve a high level of integration in your application through close and responsive teamwork. With our (permanent) holding solenoid solutions, zero-current holding and releasing achieve the next level.

  • Adjustable holding force: With our solutions, zero-current holding force can be set in the final assembly to respond to any tolerance and to enable us to find the optimum operating point for your application.
  • Minimal retaining force: We not only supply you with the solenoids, but also with the individual neutralisation current for every single solenoid to do justice to the challenging requirement on permitted residual holding force.
