Zero speed switches are used in manufacturing and flow meter applications to determine direction or speed of turbines, shafts or gears down to zero speed. The Hall effect technology fulfills a wide array of applications due to a zero speed switch's ability to detect zero speed and direction change of magnetic targets and produce a digital output. Zero speed switches are used in industrial applications to detect magnetic target's speed. Quadrature zero speed switches detect changes in a magnetic target's direction.
Thunderbird International Corp's line of zero speed switches include Intrinsically Safe, single output, dual output, additional temperature output, sanitary, hermetically-sealed and conduit-mount. Standard output (NPN) is provided by a 2.2 K ohm internal resistor to a collector which can sink 25mA. In addition, PNP and open collector types are available in order to serve all logic needs. The H Hall effect zero speed switches are used in speed applications and digital devices which switch from logic state 0 to logic 1 in the presence of a 50 gauss magnetic field.
Our H type zero speed switches are designed to switch in the presence of a 50 Gauss minimum magnetic field. The H type Hall effect transducer meets a wide array of applications due to its ability to detect the difference in a magnet's north or south pole disposition. Both uni-polar (triggered by either north or south pole magnets) and bi-polar (alternating north-south pole activation) are offered. In addition, an omni-polar model is available which responds equally to a north or south pole field and converts it to a digital pulse output.
