Case Study: KSR International achieves reduction of inductance sensor design time from 3 months to 2 weeks with ANSYS simulation

Reducing Inductance Sensor Design from Three Months to Two Weeks

KSR International, an industry leader in automotive sensors and electronic throttle controls, faced lengthy trial‑and‑error development cycles—about three months—to create custom inductance sensors for different sensing ranges and packages. To reduce engineering time, costs and time to market, KSR worked with ANSYS, leveraging ANSYS HFSS and ANSYS Nexxim for electromagnetic and circuit-level simulation.

ANSYS implemented a combined workflow: HFSS to compute full 3‑D electromagnetic fields and extract high‑frequency circuit parameters, Nexxim to simulate analog and wireless front‑end sensitivity and robustness, plus a parametric air‑gap study to account for manufacturing variation. The ANSYS simulation approach let KSR identify and correct issues before prototyping and cut custom sensor engineering time from three months to two weeks, lowering engineering costs and accelerating time to market.
