I. Inductive Position Sensors (IPS, Non-Magnetic Inductive Sensing)

Renesas’ inductive position sensors are based on the eddy current sensing principle and feature a magnet-free design. They serve as high-performance alternatives to magnetic encoders, rotary transformers and optical encoders, and are available in two main product lines: industrial grade and automotive grade.

Key Advantages

Resistance to stray magnetic field interference: As no rare-earth magnets are required, the sensors are unaffected by strong magnetic fields from motors and inverters. No additional magnetic shielding is needed, making them suitable for the complex electromagnetic environments of new energy powertrain systems;

Tolerance to harsh environments: Non-contact detection ensures resistance to dust, oil contamination and vibration; automotive-grade models operate within a temperature range of –40°C to +160°C, whilst industrial-grade models cover –40°C to 125°C;

Ultra-high precision and high-speed response: Supports up to 19-bit resolution, with absolute accuracy of up to 0.01°, propagation delay < 100 ns, and a maximum electrical speed of 600,000 rpm, suitable for high-speed motor commutation;

Flexible Form Factors: A single chip supports rotational, linear and arc position detection; target components can include aluminium sheet, steel sheet or PCB copper foil; lightweight design facilitates miniaturisation and integration.

Representative Models and Applications
