Sauer-Danfoss enhances mobile machine control with a precision EMD speed sensor for orbital motors. Employing a magnetic measuring principle delivers improved motor controllability and system flexibility. The sensor offers the highest speed resolution in the industry while simultaneously indicating direction.

Features include CAN bus communication and compliance with the Sauer-Danfoss PLUS+1™ electronic control platform. The EMD speed sensor has a reputation for extreme robustness. Being highly shock resistant and watertight (IP 69 K), this sensor is free of corroding parts, and can survive the most hostile environments.

With the EMD speed sensor, salt spreaders, forestry machinery, skid steer loaders, pavers and harvesters can reach an unsurpassed level of mobile control.

Sauer-Danfoss developed a patented contact-free sensing mechanism that follows the movement of a magnet inside a steel plug. A microcontroller inside the sensor measures both the speed and direction of the magnet as it rotates. The sensor’s high-resolution capability ultimately removes the need for external tacho generators.

The measuring principle means the EMD speed sensor can deliver very precise measurements. Pulse mode has 180 pulses per revolution as default setting, but can also be configured to a range between 20 and 120 pulses per revolution.

The EMD speed sensor is available with standard output signals, which can be customized. Standard configurations include pulse and quadrature output signals, and also a CAN bus option for reliable data transfer. Using the PLUS+1 service tool, the sensor is simple to set up, customize and adapt to OEM requirements.

Up to 253 EMD speed sensors can be connected to one CAN bus. PLUS+1 Compliance enables easy integration with other hydraulic components for optimum machine control.

The EMD speed sensor is designed for click-on mounting in the motor end-cover. Here, the angle can be easily adjusted for optimum wiring. Configuration to existing orbital motors is simple using the EMD speed sensor plug. The design allows easy field servicing because the sensor is not in contact with the hydraulic oil.
