TI Hall-effect Switches Optimized for Industrial and Automotive Uses

Hall-effect Switch

49E is a Linear Hall-Effect Switch sensor with a small size and economical price. Hall effect devices are operated by a magnetic field from an electromagnet or a permanent magnet. The user must set souring output voltage by supply voltage. The output voltage varies in proportion to the strength of the magnetic field.

Features:

• Linear
• Highly sensitive
• Small or miniature construction
• Single current sourcing output
• Can be used to detect both the poles of a magnet
• Turn on and Turn off time is 2uS each
• Inbuilt reverse polarity protection
• Suitable for Automotive and Industrial Applications

Application:

• Motor control
• Rotary encoder
• Ferrous metal detector
• Current sensing
• Position sensing
