SS443A

Key Features & Benefits

Unipolar Trigger

• Responds only to South pole; ignores North pole
  

Digital Output

• Open-collector output (requires external pull-up resistor)
  
• Direct interface with MCUs/digital circuits
  

Wide Voltage Operation

• 3.8V–30V DC power supply
  
• Compatible with 12V/24V industrial systems
  

Noise Immunity

• Built-in hysteresis (Operate: 30G / Release: 15G)
  
• Prevents chatter in unstable magnetic fields
  

High-Speed Response

• 20kHz detection frequency
  
• Ideal for rapid sensing (e.g., motor RPM)
  

Robust Protection
