### **Descriptions:**  
The **U3280M** is a bipolar Hall-effect switch designed for digital applications. It provides a reliable open-collector output that toggles based on the presence of a magnetic field.  

### **Features:**  
- **Bipolar Operation**: Responds to both North and South magnetic poles.  
- **Wide Voltage Range**: Compatible with 4.5V to 24V systems.  
- **High Temperature Stability**: Operates reliably in harsh environments.  
- **Reverse Polarity Protection**: Built-in protection against incorrect power supply connections.  
- **Low Power Consumption**: Suitable for battery-operated applications.  

This sensor is commonly used in automotive, industrial, and consumer electronics for position detection, speed sensing, and proximity switching.
