introduction to magnetic sensing reed switches a reed switch has two ferromagnetic blades reeds contained within a tubular glass envelope that is hermetically sealed at each end the contacts on each reed blade have a thin layer of precious metal material deposited on them there is usually nitrogen gas on the inside of the glass envelope to eliminate the presence of oxygen and ensure that the contacts will not oxidize reed switches are activated by a permanent magnet or an electromagnet the reed switch and magnetic field combination is commonly known as the “magnetic circuit.” snnns the relative stiffness of the reed blades along with the s n n small gap and overlap between the two contacts controls the sensitivity of the reed switch the sensitivity of the switch is the amount of magnetic field that is required to actuate the contact an open or closed mode it is measured in s n units of ampere-turns at most reed switches have a sensitivity range of 10–30 at where 10

applications proximity sensing using reed sensors— refrigerator door features and benefits appliances like refrigerators freezers and wine coolers are used to keep food beverages cold and extend their useful life these appliances contain lights to illuminate the inside compartments when the doors are open however the lights only need to turn on when a door is open to accomplish this a proximity sensor is needed to detect if the appliance door is open or closed • no physical contact required to operate the switch a reed sensor can be used to detect the position of the door in refrigerators a reed sensor is mounted to the frame of the appliance and a permanent magnet is mounted to each door each reed sensor and magnet pair is positioned so that the reed switch contacts close only when the door is completely closed the position of the reed sensor’s contacts can be monitored by an electronic control unit ecu within the refrigerator’s electronics assembly to turn

applications continued security and alarm systems— door and window alarms many types of security alarm systems use a reed switch/sensor attached to the frame of the door or window the actuating magnet is attached to the moving door or window so that when it is opened the reed sensor detects the moving magnet and opens/closes its electrical contacts—sending a signal to the alarm system features and benefits similarly reed switches can easily be mounted to circuit boards used in smoke or gas alarm systems in portable systems such as gas detectors the reed switch is used to activate the system when the handheld detector or reader is placed in the docking station in systems with smoke/gas detectors in fixed positions the reed switch can be activated with a handheld magnetic wand to put the detector in test mode • zero power required for switch actuation reed switches and reed sensors are effective solutions for many types of security and alarm sensor applications

level sensing— dishwasher water level when provided with a float magnet reed sensors can function as fluid-level sensors for example in a dishwasher a float-type level sensor is used to detect if the water level inside of the water collection pan has reached the fill limit the float sensor consists of a reed switch mounted within a shaft and a permanent magnet provided within a float housing the shaft is vertically mounted within the water collection pan so that the reed switch is positioned at the water fill limit of the pan as the water level rises the magnet within the float travels up the shaft to the point where it comes into the proximity of the reed switch the reed switch senses the presence of the magnet and signals the dishwasher’s ecu that the water level has reached its fill limit level sensors incorporating reed switch technology are low-cost solutions for any application where there is a need to detect the amount of liquid in a tank or pan they are commonly
