Product description
OH34 Series Hall switches IC are small digital unipolar Hall-effect sensor ICs，which are designed to response S pole or N pole from a permanent magnet or an electromagnet. They internally consist of a reverse voltage protection device, voltage regulator, Hall voltage generator, a differential amplifier, Schmitt trigger, and the open collector output level, which can change the magnetic field signal into a digital voltage output.
With the typical feature of small size, stable performance, OH34 series are widely used in all kinds of position control, speed detection, flow detection occasion as a non-contact switch.
Features
- 4V to 24V DC operation voltage
- Open-Collector pre-driver
- 25mA maximum sinking output current.
- Reverse Polarity Protection
- Respond to a single-pole (North or South)
Applications
- Speed measurement
- Home appliances
- Position detection
- Flow measurement
