Sensors Precision Gear Tooth Encoder Sensors
NVE's Sensor products based Hysteresis sensor material designed industrial speed applications where magnetic detection gear teeth magnetic encoder wheels required. Sensors with both analog digital outputs available. analog parts feature large signal robust characteristics which NVE's materials known (NVE's sensors damaged extremely large magnetic fields). sensor elements themselves designed provide usable output with even smallest gear teeth. Single double output versions available; second output phase shifted with respect first, provide quadrature determining direction. digital sensors take advantage high performance characteristics sensors provide duty cycle output with wide tolerance airgap temperature variations. Sensors available low-profile MSOP8, TDFN SO8, TDFN6 packages, order into tightest possible spaces. evaluation available, containing selection sensors, magnets, PCBs, that user test parts their application

Description: ABL-Series Sensors differential sensor elements that provide analog sinusoidal output signal when used with bias magnet gear tooth magnetic encoder. These chips NVE's proprietary sensor elements featuring extremely large output signal from sensor element, which stable over rated temperature voltage range. result, ABL-Series Sensors feature excellent airgap performance extremely stable operating envelope well robust reliability characteristics that sensors known for. Three different standard spacings available with fine coarse pitch encoders gear teeth. Both single bridge double bridge configurations also available. Double bridges used generate sine/cosine outputs. addition standard spacings, provide custom spacings multiple sensor elements tailored individual customer's application nominal design tooling charge. Contact further details. digital output applications, these sensors used with NVE's DD001-12 signal processing which converts their output into duty cycle modulated current signal. This allows placement sensor very small housing with wires running from sensor signal processing remote location. Thus ABL-Series sensors used smaller housings.

Notes:
ABL-Series sensors have purely ratiometric output. They will operate with input voltages lower. output signal will scale proportionally with input voltage. Maximum voltage will limited power dissipation allowable package user installation. package section more details. Linearity Hysteresis measured across linear operating range, unipolar operation. Application magnetic field excess this value will saturate sensor elements further output will obtained. damage occurs sensor elements when saturated. sensors will damaged large magnetic field.
