Maximum distance to the module
Adjustment / positioning of the sensor
Speed sensing is possible with gearwheels from module 4 down to module 1 at a maximum switching
frequency of 25 kHz. For detecting rotary speed / direction of rotation magneto-resistive sensors (MRS)
must be mounted radially with respect to the direction of motion and with their marking set vertically to it.
The dependence of the module of the detected gearwheel on the mounting distance and the maximum
detecting frequency is as follows:
Example: MRS-300-M18-...
Module m (mm)
Switching frequency f (Hz)
Reference module: Module 2 mm
100 % relation S/Sa
• Example 1: Module 1 mm
50 % relation S/Sa (Sensing distance
is halved)
• Example 2: Module 3 mm
125 % relation S/Sa (Sensing distance
increases by 1/4)
