Description

The SS495A1 is a linear Hall-effect sensor that generates an analog output voltage proportional to the strength and polarity of an applied magnetic field. Its ratiometric design means the output signal scales directly with the supply voltage, providing inherent stability against power supply variations. This principle makes it ideal for precise displacement, position, and proximity sensing applications.

Engineered for reliability, the sensor features a robust silicon construction capable of stable operation across an extended industrial temperature range. The through-hole TO-92 package facilitates easy prototyping and is compatible with standard PCB assembly processes, offering a high-value solution for motion control, lid detection, and rotary encoding systems.

Frequently Asked Questions

What does 'ratiometric' mean for this Hall effect sensor?

Ratiometric means the sensor's analog output voltage is proportional to both the applied magnetic field strength and the supply voltage. If the supply voltage changes, the output scales accordingly, providing inherent stability and simplifying signal conditioning by removing power supply noise as a variable in your measurements.

What is the required supply voltage and how do I wire the SS495A1?

The SS495A1 operates from a single 3V to 9V DC supply. The standard TO-92 pinout (flat side facing you, pins down) is: Pin 1 (left) is Vcc (supply), Pin 2 (center) is Ground, and Pin 3 (right) is the analog Output. Connect a 0.1µF bypass capacitor close to the sensor's Vcc and Ground pins for optimal noise immunity.

How do I interpret the output voltage in relation to the magnetic field?

With a nominal 5V supply and no magnetic field (0 G), the output is typically half the supply voltage (~2.5V). A south pole magnetic field (negative flux) linearly decreases the output towards 0V, while a north pole field (positive flux) increases it towards Vcc. The full-scale output swing corresponds to the ±670 G operating range.

Can this sensor be used for non-contact current sensing?

Yes, the SS495A1 is well-suited for non-contact DC or low-frequency AC current sensing. By placing the sensor near a current-carrying conductor, the magnetic field generated (proportional to the current) is detected. The sensor's linear ratiometric output can then be calibrated to provide a direct current reading via a microcontroller's ADC.
