Beat the Sensorman

Our speaker holds a PhD in microelectronics from Delft University of Technology. He studied at the Electronic Instrumentation Laboratory with a focus on silicon sensors.

After having worked for about 10 years in the pharmaceutical and semiconductor industry, he co-founded POSIC in 2001.

This company is fully focused on inductive encoders that are based on coils and integrated together with the associated electronics in one single silicon chip.

Sietse was heavily involved in the technical development and optimization of these encoders and is currently responsible for marketing, sales and business development.

Inductive encoders use a differential transformer to measure the position of a metallic object. They are well-known in the industry in the form of resolvers, LVDTs and different types of inductive sensors.

The inductive encoder consists of a transformer, the coils of which can be wire-wound coils, planar coils made in a multilayer printed circuit board or planar coils made in a silicon chip.

POSIC selected the last method in order to propose an extremely small encoder combined with the well-know robustness of the inductive sensing principle: wide temperature range, immunity against magnetic fields and insensitivity to oil, grease, particles and dust.

The result is a very small encoder with a very high robustness, ideally suited for integration in space-constrained applications, such as electric motors, direct drives, robots, automation equipment, medical equipment and precision-instruments.
