Non-contacting two-channel speed sensor FAHZ53 with signal amplifier, difference-hall-effect principle NORIS Scan type Speed Sensor FAHZ53 Application range Speed sensors of the FAHZ53 series are especially designed for use in: Transport technology. They measure the speed of ferromagnetic toothed wheels. Furthermore they can be used to measure any movement of ferromagnetic parts, e. g.: • Toothed wheels with different tooth forms • Bolt heads • Lands detects holes, openings or grooves • Impulse bands for plain shafts (accessories) Measuring principle Speed sensors of the FAHZ53 series operate according to the difference-hall-effect principle. Two closely spaced Hall elements are located on the sensor chip. The field of the magnet generates a constant voltage in the Hall elements. Ferromagnetic objects with an interrupted surface moving past the Hall elements cause the Hall voltage to change. When the moving part covers a Hall element and the other does not, a differential voltage is generated to provide a measuring signal. The frequency of this signal is proportional to the speed of movement (rotational speed). The difference-hall-effect principle is direction sensitive. Specific features • Robust and high quality housing: IP68 pressure-tight and individually tested at 5 bar (see technical data) • Speed sensor with two square wave signals, signals 90° offset • Excellent vibration and shock resistance • High degree of EMC immunity for difficult electrical environment • Straight connection outlet • Detection of very low speed (near zero speed) • Due to its design especially suitable for transport technology Datasheet DB-FAHZ53-EN | V03.12 | 23/09/2016 | Valid from product revision Rev.Cl | www.noris-group.com | sales@noris-group.com
