| KMT37 Angular Sensor • AMR Sensor with 180° period • For the use at moderate field strengths • High accuracy • Reliable SO8-package • Qualified for automotive applications The KMT37 is a magnetic field sensor based on the anisotropic magneto resistance effect, i.e. it is sensing the magnetic field direction independently on the magnetic field strength for applied field strengths H>=14 kA/m. The sensor contains two parallel supplied Wheatstone bridges, which enclose a sensitive angle of 45 degrees. A rotating magnetic field in the surface parallel to the chip x-y plane will deliver two independent sinusoidal output signals, one following a cos 2α and the second following a sin 2α function, α being the angle between sensor and field direction see Figure • Contactless angular position • Design optimized linearity • High accuracy • Low cost, low power • Self diagnosis feature • User has complete control over signal evaluation • Reliable SO8-Package • High rotational speed possible • Extended operating temperature range -40 °C to +150 °C • Ideal for harsh environments due to magnetic sensing principle • RoHS compliant lead free • Absolute and incremental angle measurement • Motor motion control • Robotics • Camera positioning • Potentiometer replacement • Position measurement in medical applications • Automotive steering angle, torque, etc. KMT37 2015-July KMT37 Angular Sensor CHARACTERISTIC VALUES Parameter Condition Absolute maximum ratings Supply voltage Operating temperature Storage temperature Operating conditions Supply voltage Applied magnetic field General parameters Bridge resistance T = 25 °C max. signal amplitude T = 25 °C, H = 25 kA/m Offset voltage 2 T = 25 °C, H = 25 kA/m Hysteresis 1 Repeatability H = 14 kA/m H = 25 kA/m Accuracy 1 H = 14 kA/m H = 25 kA/m TC of amplitude H = 25 kA/m, 3 TC of bridge resistance 3 TC of offset voltage H = 25 kA/m, 1 , 2 Amplitude synchronism H = 25 kA/m, 4 Sensitivity zero crossing H = 25 kA/m, 4 , α1 = 135°, α2 = 0° ORDERING CODE DEVICE KMT37 DELIVERY FORM TnR Tube MOQ 1 Reel 2500 pcs. 1 Tube PART NUMBER G-MRCO-037 on request ORDERING INFORMATION NORTH AMERICA EUROPE ASIA Measurement Specialties, Inc. 1000 Lucas Way Hampton, VA 23666 United States Phone +1-800-745-8008 Fax +1-757-766-4297 Email Web: MEAS Deutschland GmbH Hauert 13 D-44227 Dortmund Germany Phone +49- 0 231-9740-0 Fax +49- 0 231-9740-20 Email Web: Measurement Specialties China Ltd.
