The MHRM series of hall sensors has a maximum operating distance not less than 0.7 mm. Its gears are made of ferromagnetic material and they have a width greater than 6 mm and a minimum size of module 1. Also, the unit can switch frequencies between 0 and 15 kHz, and it operates under voltages between 8 and 28 Vdc. More so, consumes 20 mA without any load, and produces an output not greater than 30 mA. In addition to that, output A is a push-pull and B is none. Finally, the unit is short circuit and reverse polarity protected.
