Gruner solenoids for touch-based or ’haptic’ feedback are bespoke solutions that are developed right at the concept stage of a project. How does the product function? What task does a linear solenoid have to perform? What should the user do? How can we solve that problem? The solenoid solutions you obtain from us are based on many years of experience and great expertise, combined with innovativeness.

A particular highlight in our portfolio: customer-specific applications for the automotive industry. Safety, reliability, size, weight, lifetime quality, time-to-market, flexible volumes, availability: here, everything comes together to ensure that you have a good experience with our solenoids.

The challenge posed by the rising number of consumers and growth in the proportional share occupied by electromechanics: an ever greater number of solenoids in vehicles with a constant stream of new functions are faced by increasing restrictions on space and weight. One particular benefit of our e-core solenoids for haptic applications: the solder-free connection of enamelled copper wire and the strands provided by insulation displacement.

Gruner valve solenoids provide reliable functionality for many medical appliances. They are ideal for metering systems, medication pumps, as control valves for blood pressure gauges and for all applications involving the delivery of a medium.
