Reed Switch:
The reed switch utilizes two small soft-magnetic elements inside of a glass bulb. The elements change their continuity state in the presence of a magnetic field. A normally open reed switch will close when the proper magnitude and shape field is presented to it. This sensor makes use of the flux components running parallel to the bulb and soft-magnetic elements. This geometry usually requires the magnet to be oriented parallel to the bulb. Inaccurate triggering and “dead-spots” will be observed when utilizing a magnet oriented perpendicular to the bulb and elements.
Many electronic systems require input data concerning position, motion, and speed. Most motion and speed sensors use a magnet as the sensing element or sensed target to detect rotational or linear speed. The types of magnetic speed sensors include magnetoresistive (MR), inductive, variable reluctance (VR), and Hall-effect. In addition, the potentiometer and commutator pulse counting can be used to detect position. ndfeb sensor rod magnet n35sh
Some systems require the use of photoelectric sensors that use light sensitive elements to detect the movement of an object. In addition, solid state accelerometers, axis rotation sensors, yaw sensors, and roll sensors are becoming common components on many systems. This chapter will explore the operation of common position and motion detection sensors.
Potentiometer
A common position sensor used to monitor linear or rotary motion is the potentiometer. A potentiometer is a voltage divider that provides a variable DC voltage reading to the computer. These sensors are typically used to determine the position of a valve, air conditioning unit door, seat track, and so on.
