The gear sensor kit is used to test the speed of the gear. It displays the number of revolutions per minute. The gear sensor detects the number of teeth of the metal gear plate and gear pinion to convert it to the speed of the device per minute.
Tachometer parameters:
Appearance 48*96*75MM, (width*length*deep), opening size: 45*92MM, voltage power supply AC 220V, DC24V 2 power supplies, whichever the customer needs, just take the kit .
Sensor parameters: M12*1*45mm, threaded part 30mm, 3-wire(Brown, blue black)Direct measurement of gear speed, detection distance 2mm, NPN output, voltage DC 6-30V.
Gear requirements: gear thickness above 8mm, tooth spacing and tooth width above 2mm, tooth depth 2mm, equal width tooth, iron material

Product installation:
1. When installing, use the nut that comes with the sensor to fix it on the mounting hole. The fixing device is recommended to use non-magnetic material(Copper, stainless steel, etc.), The sensor should be installed directly opposite the tooth surface, and the distance between the tooth surface and the front surface of the sensor should not be greater than the rated detection distance.
2. The detection distance is related to the modulus of the matching detection gear. The larger the modulus, the longer the effective detection distance.
