3144 Hall Effect Switches

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both temperature and supply voltage changes. The unipolar switching characteristic makes these devices ideal for use with a simple bar or rod magnet.

Specification:

• Superior Temp. Stability for Automotive or Industrial Applications
• 4.5 V to 24 V Operation … Needs Only An Unregulated Supply
• Open-Collector 25 mA Output … Compatible with Digital Logic
• Reverse Battery Protection
• Activate with Small, Commercially Available Permanent Magnets
• Solid-State Reliability
• Small Size
• Resistant to Physical Stress
