New Vishay Intertechnology Position Sensor Offers Robust, High-Resolution Performance for Robotics and Other Precision Industrial and Military Applications
60 mm Device Features > 13-Bit Accuracy, 19-Bit Resolution, and > 16-Bit Repeatability
MALVERN, Pa. — Oct. 7, 2019 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new high precision position sensor that offers more robust performance than existing absolute encoders and better resolution and accuracy than traditional Hall effect sensors for industrial robotics and other demanding applications. The new 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 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’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 RAMK060 are:
- self-calibration to compensate for mechanical misalignment
- built in self-monitoring
- memorization 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. Customers may request samples by sending an email to firstname.lastname@example.org.
