Medical and mobility sensors


Piher manufactures quality products with brand consistency allowing our clients to focus on their core business.

We institute mandatory training and testing on control procedures for all of our employees, and follow the highest levels of onsite security and best practices.


With the increased use of electronics in medical equipment, access to the best health care has been improved for more people. At the same time, safety and cost concerns and have raised including telemedicine and IOT (The internet of things).
Piher sensors and controls are succesfully providing responsive operation, compatibility with many existing controllers, and helping meet faster the specifications required by the most demanding regulations.

Technology – medical

Touchless working principle for medical sensors.

Superior to other sensors technologies in terms of cost and convenience, our vertical hall effect sensors are the perfect replacement to other technologies such as resolvers, capacitive displacement sensors,.

Measurement of linear position using variation of magnetic field amplitude induced by the displacement of a moving magnet has been intensively developed over the last fifteen years. However, these solutions have limits in terms of angular range and temperature influence.

The technology used by Piher is only sensitive to the flux density coplanar with the IC surface.

The absolute position information is computed from both vectorial components of the flux density (i.e. BX and BY) of a magnet. Then, an output signal proportional to the decoded position is produced.
