Input Devices

With best-in-class input devices built on Hoffmann + Krippner innovation, we enable you to create world-class products that delight your customers and users.

No device or product can succeed if the interface between it and its user fails.

However, getting the human-machine interface (HMI) just right requires product designers and managers to untangle a thorny knot of questions and considerations around functionality, quality, technical reliability, usability, economy of design and of cost, durability, and more.

Thankfully, Hoffmann + Krippner makes input devices easy.

We know that an excellent HMI is critical to getting people to use – and love – your product, and then come back to you for more. We are proven experts at both the construction of excellent devices and the design of user-pleasing interfaces. With peerless German craftsmanship and global leadership in the design and manufacture of a wide array of advanced input devices, we can enable you to create an outstanding product that stands out even in the most crowded markets and industries.

How does your product look, feel, and function? When it incorporates Hoffmann + Krippner engineering, the answer is always: exceptional.

Input Devices Potentiometer


We offer wear-free, low-cost potentiometers that work exceptionally well anywhere precise and careful controls, inputs, or measurements are needed. If your application needs displacement and/or angle sensors, Hoffmann + Krippner, in exclusive partnership with German manufacturer Altmann GmbH, can provide high-quality potentiometer solutions. Furthermore, Hoffmann + Krippner’s ultra-thin, fully-sealed, and easily customized Sensofoil® membrane potentiometers can fit into restricted installation conditions and offer extremely long lifecycles. Similarly, Hoffmann + Krippner SensoInk® allow us to create polymer potentiometers that combine the advantages of PET (flexibility and cost) with high-strength polymer pastes that can surpass the lifecycles of other PET-based potentiometer products.
