Description

The SS496A1 is a digital Hall-effect sensor IC from Honeywell that generates a ratiometric output voltage in response to an applied magnetic field. Its output is linearly proportional to the magnetic flux density, simplifying interface with analog-to-digital converters (ADCs) in microcontrollers. The device is engineered for stable operation across an extensive industrial temperature range.

This sensor is ideal for applications requiring precise displacement or proximity detection, as its ratiometric nature minimizes errors from supply voltage variations. The through-hole TO-92 package provides a robust and easy-to-solder solution for prototyping and volume production in compact electronic assemblies.

Frequently Asked Questions

What is the operating voltage range for the Honeywell SS496A1 sensor?

The SS496A1 is designed for a 3 Vdc nominal supply voltage. Its ratiometric output characteristic means the output voltage scale is proportional to this supply voltage, making it suitable for low-power, battery-operated systems. Always consult the datasheet for absolute maximum ratings.

How does the 'ratiometric' output work, and how do I interface it with a microcontroller?

A ratiometric output means the sensor's output voltage is a ratio of the supply voltage. For example, at zero Gauss, the output is typically Vcc/2. This linear analog voltage can be directly connected to an ADC input on an Arduino, Raspberry Pi, or other microcontroller. This design inherently compensates for minor supply voltage fluctuations.

What is the difference between the operating point and the full magnetic range?

The specified operating point range of -840 G to +840 G defines the magnetic flux densities where the sensor's output is linear and within its specified accuracy. Applying fields beyond these limits may saturate the output. The sensor can reliably detect the presence and polarity of magnets within this defined linear range.

Can this sensor be used for speed sensing on a rotating gear or wheel?

Yes. By mounting a small magnet on the rotating component and positioning the SS496A1 nearby, each pass of the magnet will create a detectable peak in the output voltage. This signal can be conditioned by a comparator or sampled by a microcontroller's ADC to calculate rotational speed or RPM.
