Spring naar Magnetic sensors – Reed switches actuated by magnets are commonly used in mechanical systems as proximity sensors. Examples are door and window sensors in burglar alarm systems and tamperproofing methods (however they can be disabled by a strong, external magnetic field). All are well-proven designs manufactured to our high standards. With a rich history of leading the industry in providing magnetic sensing solutions, our experts are committed to delivering the best products and solutions for your . Intruder alarms and model railroads often use them too.

When the device is exposed to a magnetic fiel the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is remove the reeds separate and the switch opens. They are made from two or more ferrous reeds encased within a small glass tube-like envelope, which become magnetised and move together or separate when a magnetic field is moved towards the switch.
