Please note that the EMD speed sensor may fail. Output signals may not represent correct rotation speed
or direction.
Any application of the EMD speed sensor should be subjected to appropriate hazard and risk assessment,
according to relevant safety standards for the application.
Reliability data MTBF for the EMD speed sensor are available on request from your Danfoss
representative.
Function of the speed sensor is to detect the shaft speed and the direction of rotation. The sensor is
mounted to the endcover of a Danfoss orbital motor and senses the speed from a magnet that is rotating
inside the motor. Because of the digital output signals for speed and direction and a non speed
dependent output voltage level, the sensor is ideal for high and low speed measurements.
The speed sensor is designed for rugged outdoor, mobile or heavy industrial speed sensing applications.
The detection of the speed is contactless. It is a “plug and perform” device that does not need any
calibration or adjustments.
Mounting with a snap/click lock and can be adjusted in 36 different positions.
Available for following LSHT-motors: OMT, OMV, TMK, TMT and TMV.

Wiring diagram
Conversion diagram
It is possible to replace an Orbital Motor with EM-sensor with PNP or NPN open collector output with an
Orbital Motor with EMD-sensor. Conversion diagrams show how it is possible to replace present sensor
with EMD-sensor.
The resistor RL which is used in the current NPN/PNP diagram is not needed but can under certain
conditions remain in the circuit:
If RL < UDC/10 mA remove or increase the size of the resistor.
•
If RL > UDC/10 mA no change needed.
•
In case the EM-sensor and the controller have different power supply, it is needed to modify the circuit so
that the EMD-sensor has the same power supply as the controller.
