Vishay Intertechnology offers a new high precision position sensor

Vishay Intertechnology has recently introduced a new high precision position sensor that offers more robust performance than existing absolute encoders.

Vishay Intertechnology’s sensor has better resolution and accuracy than traditional Hall effect sensors for industrial robotics and other demanding applications.

VishayVishay Intertechnology’s RAMK060 rotational absolute magnetic kit encoder uses advanced contactless technology to achieve > 13-bit accuracy, 19-bit resolution, and > 16-bit repeatability while maintaining robustness against external magnetic fields, moisture, airborne pollution, vibration, mechanical shock, and changes in temperature.

The device features a useful electrical angle of 360° and works over a temperature range of -40 °C to +85 °C, with higher maximum temperatures available on request.

The rotor + stator kit design of the RAMK060, as well as its off-axis design (for hollow shaft mounting), slim ~6.5 mm profile, and light weight (< 55 g) make it ideal for applications where little space is available but an angular position needs to be detected with high accuracy.

The Vishay Intertechnology’s RAMK060 has an outside diameter of 60 mm and inner diameter of 25 mm. Several multi-turn variants are available, including connection to a backup battery when system power is off. SPI, SSI, or Biss-C output signals are available.

Vishay Intertechnology’s patented design is particularly suited for applications calling for precise and repetitive motion such as arm joints for industrial robots and collaborative robots; steering wheels for automated guided vehicles; and machine tools used in printing, textile manufacturing, and milling.

The key advantages of the Vishay Intertechnology’s RAMK060 are:

  • Self-calibration to compensate for mechanical misalignment
  • built in self-monitoring
  • memorisation of the last absolute position before power-off

This technology architecture provides the best performance with safety guarantees.

Samples and production quantities of the RAMK060 are available now, with a lead time of 16 weeks for larger orders.
