Magnetic Sensors - Switches (Solid State)

Magnetic Sensors - Switches (Solid State) are normally used in a range of automated control systems, such as those which are employed within robotics, automation, industrial process control, level measurement, and a variety of medical applications. The SS449R is one of the most widely used solid state magnetic switches, allowing for the measurement of the presence, absence, direction, and/or strength of a magnetic field.

Application Field

The SS449R is a powerful, versatile device which finds use in a wide variety of applications, making it an ideal candidate for inclusion in many types of systems. For example, industrial applications often employ this switch type for applications such as position sensing, position control, or even health monitoring. In medical applications, it is used for bedside detection of vital signs. Similarly, it finds use in robotics systems and in automated control, as a cost effective and reliable way of gathering data regarding the position and strength of a particular magnetic field.

Working Principle

At the heart of the SS449R is a Hall Effect sensor. This sensor uses the principles of physics to accurately detect changes in an ambient magnetic field. Put simply, when a magnetic field is present, it causes a disruption in the electronic signal passing through it, which is picked up by the SS449R. This allows the switch to communicate to the connected system the strength and the direction of the magnetic field. The SS449R also offers user adjustable sensitivity, allowing for variable reading thresholds to be set across a range of applications. This feature allows changes in the magnetic field reading to be picked up at a prespecified level. This particular switch is also available with a number of different output configurations, such as Digital and PWM, meaning it is incredibly flexible for use in all types of systems.Overall, the SS449R is an immensely powerful magnetic switch, which combines versatile outputs, adjustable sensitivity, and reliability. It is therefore perfect for applications across a range of industries, such as industrial and medical, which require accurate and reliable measurements of magnetic fields.
