Sauer-Danfoss enhances mobile machine control with a precision EMD speed sensor for orbital motors. Employing a magnetic measuring principle improves motor controllability and system flexibility. The sensor has high speed resolution while simultaneously indicating direction.
CAN bus communication and compliance with the Sauer-Danfoss PLUS+1™ electronic control platform are among the new features. With the EMD speed sensor, salt spreaders, forestry machinery, skid steer loaders, pavers and harvesters can reach a new level of mobile control.
Patented Contact-Free Sensing
Sauer-Danfoss has developed a patented contact-free sensing mechanism that follows the movement of a magnet inside a steel plug. Even small rotational movement is detected due to a direct connection to the cardan shaft via a flexible axle. A microcontroller inside the sensor measures both the speed and direction of the magnet as it rotates – a task that previously required two sensors. Additionally, the sensor’s high resolution capability removes the need for external tacho generators, decreasing costs for consumers.
Swift Integration
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.
Click-On Mounting
Unlike its side-mounted predecessor, the EMD speed sensor is designed for click-on mounting in the motor end-cover. Here, the angle can be adjusted for 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.
Tough In All Conditions
The EMD speed sensor is shock resistant and watertight (IP 69 K) and the sensor is free of corroding parts.
