The solution for extremely precise feedbackHaptic-Sense-Audio-Actuator

Our HSA (Haptic Sense Audio) actuators are three-in-one actuators, combining haptic feedback, force sensing, and audio output.

  • Maximum flexibility of the haptic signal: For a wide range of signal shapes and frequencies between 40Hz and 20kHz.
  • Extremely precise feedback: There is no latency and very short event times can be achieved (<9- 15ms).
  • Variable application: The actuators are available in different sizes, from single buttons to large displays.

The solution for strong performance - simply integratedVoice Coil Actuator

The flexible product design and stable performance of our voice coil actuator speaks for itself. 

  • Adjustable resonant frequency
  • Configurable strands and connectors (AWG 28-24)
  • Low frequency tolerances over temperature
  • Suitable for masses up to approx. 100 grams (one actuator)
  • Easy assembly (tape)

The solution for major tasksPulling solenoid

Pulling solenoids can also be used as haptic actuators. These actuators can be integrated oscillating systems These actuators can be integrated into single or coupled damped oscillation systems, which enables them to deal with big masses.

  • Solder-free connection technology: Reliable process contacting of stranded wires and enameled wires using insulation displacement connections (IDC) or directly with the printed circuit board (press-fit).
  • Active damping: With targeted double impulses, it is possible to influence the damping of an entire system.
  • Rapid & high levels of force: Measures involving reduced eddy currents achieve the required rapid build-up of flux and force.
  • Dynamic properties: Here, high forces can be achieved within 1-3 ms for moving masses of > 300 grams.

The solution for big tolerance chainsLinear solenoid actuator

These types of solenoids operate in active haptic systems that are based on the physical principle of an oscillating system with single damping. Due to the linearity across a wide range of linear solenoids, tolerance problems become a relatively minor issue.

  • Plug & Play: Depending on the solution, it is possible to achieve direct mounting and contacting with the PCB.
  • Big tolerances: Tolerances of > 1 mm can be achieved without any problem by influencing the characteristic curve in a targeted manner.
  • Typical service life: Depending on the application and the armature mounting, 1-5 million switching cycles are possible.
