What is the clearance between the sensor and the gear ring?
In ensuring that the gears do not come into contact, the sensor is installed as close as possible to ensure that the sensors work properly.
There are many kinds of sensors, such as Holzer, photoelectric and so on
Is generally a few millimeters, can use the sensor slowly close to the gear and gear, until the signal output from the output signal, just place until the gears are sensor sensing distance.
