Vishay RAMK060 Rotational Absolute Magnetic Kit Encoders

Vishay MCB RAMK060 Rotational Absolute Magnetic Kit Encoders are high-precision position sensors that offer 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 encoders use 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 temperature changes. The devices feature a 360° electrical angle and work over a -40°C to +85°C temperature range. The RAMK060 components feature an outside diameter of 60mm and an inner diameter of 25mm. Several multi-turn variants are available, including connecting to a backup battery when system power is off.

Vishay MCB RAMK060 Rotational Absolute Magnetic Kit Encoders patented design is particularly suited for precise and repetitive motion applications, 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.
