non-contact sensor
EZ1000, PR642x
Eddy current sensors are also well suited for speed sensing
You can also directly paste a piece of copper foil on the shaft for measurement
When selecting the appropriate type (size) of the sensor, measurements can be made on various grooves, teeth, holes, wheels made of different metal materials.
The measurement is less sensitive to the shape and precision of the tooth and the cleanliness of the environment
The output signal of the sensor (or converter) has a pulse shape which is influenced by tooth profile, measuring wheel material or air gap setting and often requires further processing by suitable shapers
For example, A 3311 converter (also includes a sensor converter) or A6500-UM, A 6312 monitor is suitable
The SIL3 tachometer A 6300 SIS and its predecessors epro DOPS and MMG1000TS also use this type of sensor
For new projects, we recommend the EZ1000 Series sensors
