Magnetic Sensors - Switches (Solid State) are advanced types of sensors utilized to detect changes in magnetic fields. The primary function revolves around identifying presence or absence of magnetic objects or changes in magnetic fields. They are specially crafted to act as switches when a magnetic field is present. This type of sensor is non-contact, meaning they don't require direct contact with the object being sensed, thus increasing their lifespan and making them suitable for harsh environments. They are generally compact, highly reliable, and have a long operational life.
These sensors are inherently equipped to execute specific roles in numerous applications. They are found extensively in industries such as automotive, for detecting the position of car doors or ignition key; in industrial applications for position, proximity and speed sensing; and in consumer electronics for reed switching and other functions. Key characteristics of these sensors include their robustness, precision, and ability to operate in a broad range of temperatures. Due to their efficiency and reliability, they are typically produced by established manufacturers like Honeywell, TE Connectivity, Diodes Incorporated, and others.
