Honeywell SS490 Series Hall Effect Sensor, 10.5V Maximum Supply Voltage, -40°C Minimum Operating Temperature - SS495A

This Hall effect sensor provides contactless magnetic field detection for electronic and electromechanical systems, offering ratiometric analogue output for proportional position or field-strength measurement. Designed for surface mounting in Compact assemblies, it operates across a wide temperature range suitable for demanding environments and accepts a range of supply voltages for flexible integration into control and sensing circuits.

Features and Benefits:

• Ratiometric output with 5V supply ensures proportional signal scaling
  Accepts up to 10.5V maximum supply and operating voltage for flexibility
  Operates from -40°C to 150°C for extended temperature tolerance
  Surface-mount 3-pin Terminal simplifies automated PCB assembly
  Low switching current of 1.5 mA minimises load on driving circuitry

Applications

• Suitable for rotary position sensing in motor controllers
  Ideal for proximity detection in industrial automation systems
  Used for contactless speed measurement in electromechanical drives
  Can be used for magnetic field monitoring in sensor arrays
  Used with automotive-grade temperature environments in control modules

What physical profile should I allow for PCB clearance?

The package has a low profile with a depth of 1.6mm and length of 4.06mm, enabling tight component stacking on densely populated boards.

How does the device behave when supply voltage varies?

Its output scales proportionally with supply, providing ratiometric analogue signals that track supply changes within the permitted voltage range.

What mounting method is required for reliable connection?

It requires surface mounting using its three-terminal arrangement designed for soldering to PCB pads and assembly by standard SMT processes.

Can this be used in higher-voltage control systems?

It is suitable where the supply does not exceed the specified maximum of 10.5 V
operation above this limit must be avoided to prevent device stress.
