History and Mission

POSIC is a privately-owned company, specialized in miniature inductive encoder kits. The company is headquartered in Neuchâtel, Switzerland and was founded in April 2001 as a spin-off from CSEM (Swiss Center for Electronics and Microtechnology).

Our mission is the development, production, marketing and sales of miniature inductive position sensors based on our coil-on-chip technology. We provide complete position sensing solutions for motion control and mechatronic applications. Markets served include industrial automation, medical devices, automotive, robotics, instrumentation, machine-tools, laboratory automation etc.

Technology

Our position sensors and encoder kits are all based on the “coil-on-chip” technology, which enables the fabrication of the world’s smallest inductive sensors. The inductive sensor (a differential transformer) is fabricated on top of an electronic chip, which contains all the electronics necessary for sensor-operation, interpolation, linearization and interfacing (the picture shows a device with coils and electronics on two separate chips).

Standard products and customized solutions

Custom solution: IS1101 inductive sensor on brass holder with cable and connectorWe offer a number of
standard products in the form of inductive sensors and miniature encoder kits, including accessories like codewheels, linear scales, cables and connectors. In order to fully meet our customer’s requirements, we customize encoders, codewheels, scales, cables and connectors according to the requirements of a specific application.
