Hall effect sensors with output proportional to supply voltage and the strength of the magnet field
Single current sinking or current sourcing linear output
Rail-to-rail operation provides more useable signal for higher accuracy
Responds to either positive or negative gauss
Good temperature stability
Typical applications include; current sensor, motor control, position control, encoder, metal detection, vibration sensor etc

Measure the voltage and strength of a magnetic field with this ratiometric Hall effect sensor from Honeywell. It can respond to positive and negative gauss to show imbalances at either end of the magnetic spectrum. A Hall effect integrated circuit chip provides a high level of temperature stability and sensitivity. This allows the device to function across a broad operating temperature range of -40°C to +150°C, making it suitable for use in hot and cold environments.

• Low power consumption of 7mA for energy-efficient operation
• Compact size of 4.06 (length) x 3 (width) 1.6mm (depth) for use in areas where space is limited
• Laser-trimmed thin-film resistors on the chip to ensure reliable readings
• Quad Hall sensing element minimises mechanical or thermal stress to give you a stable output

• Current sensors
• Motor and position controls
• Metal detection
• Vibration sensors

A Hall effect sensor like this one measures the strength of a magnetic field and converts it to a proportional electrical voltage reading.
