OH137 UNIPOLAR HALL EFFECT POSITION SENSOR TO-92S

The OH137 Unipolar Hall Effect Position Sensor TO-92S is a monolithic integrated circuit (IC) that utilizes the Hall Effect to sense the presence of a magnetic field. This sensor responds specifically to the South pole of a magnet. When a South magnetic pole is brought within close proximity to the sensor’s active area, the output signal transitions to a specific state, indicating the presence of the magnetic field. Conversely, when the South pole is removed, the output reverts to its original state.

Key Features of OH137 Unipolar Hall Effect Position Sensor TO-92S:

• • High Magnetic Field Sensitivity: This sensor is designed to detect even weak magnetic fields, ensuring precise operation in diverse applications.
  • Unipolar Operation: The unipolar design simplifies circuit design by responding only to one magnetic field polarity. This eliminates the need for complex polarity detection circuitry.
  • Wide Operating Voltage: The OH137 can operate with a wide range of power supplies, from 3.5V to 24V, offering greater flexibility for integration into existing systems.
  • Exceptional Temperature Stability: Consistent performance is delivered across a wide temperature range (-40°C to 125°C), making the OH137 suitable for use in demanding environments.
