Gear sensor Term definitions

Module

This is a unit of measurement for the size of the teeth on a gear or rack.
For gears, it is the reference circle diameter divided by the number of teeth.
When gears mesh, the circles that they touch are the reference circle, and this diameter is the reference circle diameter.
When gears mesh, they will not mesh unless they have the same module.
If the module is m and pi is π , then the pitch, which is the distance between the teeth, is m π [mm].

Gear width

The axial length (thickness) of the gear.

Rack

It is a rod-shaped gear with many teeth cut into a straight rod.

Output (Open drain)

The output MOSFET drain is an open type and can directly open and close currents of the rated load current and lower.Please note that the output MOSFET will burn out if the magnetic sensor is turned on by short-circuiting without connecting the load.
When using as a voltage output type, for Nch MOSFET open drain output, connect a load resistor externally between Vcc and OUTPUT and use the voltage between OUTPUT and GND as a control signal.
For Pch MOSFET open drain output, connect a load resistor externally between OUTPUT and GND and use the voltage between Vcc and OUTPUT as a control signal.
