Vishay Intertechnology 45 mm Inductive Position Sensor Encoder Enables Reliable Operation Near Electric Motors
Vishay Intertechnology has introduced the RAIK045I MP, a new medium-precision position sensor built on inductive technology. This absolute inductive kit encoder is designed for demanding industrial applications, offering a reliable and accurate positioning solution. A key differentiator of the RAIK045I MP is its immunity to external magnetic fields, allowing it to operate effectively in close proximity to electric motors, where traditional magnetic encoders might experience reduced accuracy.
This device serves as a cost-effective alternative to higher-performance encoder solutions, combining 16-bit resolution, repeatability of ≥ 14 bits, and rotation speeds up to 10,000 rpm. Its compact and lightweight design simplifies mechanical integration, saves space, and reduces system inertia. The inductive technology not only provides immunity to magnetic fields but also ensures robustness against moisture, airborne pollution, vibration, mechanical shock, and temperature variations, making it suitable for harsh industrial environments.
