Product Information

Back to top
The Micronas HAL 37xy Programmable Hall-Effect Sensor Family for Rotational or Linear Position Detection based on 3D HAL Technology is the second sensor generation using Micronas’ proprietary 3D HAL technology, which offers a further improvement of the angular performance. Compared to the first generation, a 30% lower angular error has been achieved.
   

Operation with magnetic fields down to ±20 mT is enabled thanks to the improved technology. HAL 3715 and HAL 372x provide a linear, ratiometric analog output signal with integrated wire-break detection working with pull-up or pull-down resistors. HAL 373x  features  digital  output  formats such as PWM and SENT SAEJ2716 rev. 2010. The digital output format is customer programmable.
   
The signal path of HAL 37xy consists of two channels (CH1 and CH2). Depending on the product variant, two out of the three magnetic field components are connected to Channel 1 and Channel 2.
    
   
    
The sensors can be used for angle measurements in a range between 0° and 360° (end-of-shaft and through-shaft setup), as well as for robust position detection (linear movement or position). The in-system calibration can be utilized by the system designer to optimize the performance for a specific system. The calibration information is stored in the on-chip EEPROM.

The HAL 37xy is programmable by modulating the output voltage. No additional programming pin is needed.

Major applications:

• Linear movement measurements (EGR, clutch, transmission position)
• Rotary position measurements (gear selector, motor air management)
• Non-contact potentiometer

Symmetry Electronics (and its e-commerce division: SemiconductorStore.com) is an authorized Micronas distributor.
