Application Examples
Various solutions and application examples that are utilizing Reed Switches or Reed Sensors - learn more and get inspired!
Position Control
To check the (end)position of a mechanical part of the application.
Washing Machine
A magnet attached to the drum activates a Reed Switch when the drum position is correct (lid upside). The Reed Switch gives a closed signal to the control unit to unlock the door.

Hydraulic- or Pneumatic Cylinder
Magnetic Sensor based on Reed, Hall or xMR technology are used to detect the (end)position or movement of hydraulic/pneumatic cylinders in industrial automation applications.
Customized housings enable different ways of assembly. LEDs are used to give a visual indication of the Sensors status, and the cylinder position respectively.
Different switching sensitivities and electric properties adjust our Sensors to customers switching distance and voltage requirements. We provide tailor-made Sensor design including individual cable and connector fitting.

Security Systems/Building Technology
Windows and doors are monitored by Reed Sensors in the windows/doors frame and magnets attached to the window/door. If the window or door is opened with activated security system and alarm is issued.
Another application:
Modern energy saving houses or houses with an open fire place need a security system that enables open fires or working kitchen hoods only when a window is open.

Non-Touch-Switching
Certain functions are switched on or off by using a permanent Magnet and a Reed Switch or Reed Sensor.
Smoke Detector
Smoke detectors are activated when mounted into their mounting plate by a magnet actuating a Reed Switch inside the smoke detector.
No battery drain occurs until the smoke detector is activated at its place of installation.

Refrigerator
A magnet inside the fridge door de-activates a (SMD) Reed Switch inside the fridge housing when the door is opened. Light will be switched on and a air blower, if existing, will be switched of.

Level Sensing
Safe, simple and reliable liquid level detection.
Fluid tanks
Tanks in industrial environments or machines contain operating fluids, lubricants and other crucial materials.
The level of these materials is detected with Level Sensors or special design Reed Switch Chains and matching floats containing a magnet.

Automatic Coffee Maker
A Reed Sensor integrated into the coffee maker housing is activated by a magnet in a float, floating inside the detachable water tank.
When the water level sinks to a certain height an alarm is issued, no more coffee will be produced to protect the machine from running dry.

Condensate Dryer
When drying wet clothes in a condenser a huge amount of water remains in the condensate tank. The level of this condensate water is checked with Reed Technology, a warning is issued when the condensate reaches a critical level.
Some dryers have an integrated condensate pump to remove the condensate from the dryer. This pump is also controlled by the Reed Sensor or Level Sensor.

Flow Detection
Detects the absence or presence of flow in a system and uses the flow to generate a signal.
Dish Washer
Modern dish washers detect the used water quantity with a fan with magnets and matching Reed Switches on a PCB to ensure a most efficient and economical washing procedure.

Water-Meter
Water meters in buildings check the water usage electronically by using a fan with magnets and Reed Sensors.
This electronic information can be submitted to a computer or via remote transmission.

Speed Measuring (RPM)
Rounds-Per-Minute calculation to obtain speed, mileage and other operational data.
E-Bike Speed and Motor control
Electric motors of e-bikes and pedelecs are supporting the deployed body power in subject to the current speed. The current speed is measured with a spoke mounted magnet and a Reed Switch at the fork.
Each wheel turn activates the Reed Switch, the motor control united counts activations and multiplies them with the wheel diameter. Additional motor power is set free according to the measured speed.

Bicycle Speed-Meter
To calculate the speed and the mileage when riding a bicycle, a speedometer is used. A spoke mounted magnet activates a Reed Sensors sitting at the fork.
The signal is transmitted to the bicycle computer which calculates speed an mileage with the number of wheel turns (means Reed Sensor activations) and the wheel diameter.

Windspeed Metering
Modern buildings use automatic blinds to provide shadow and heat protection. These blinds a very prone to fast winds and storms.
A wind meter uses a fan with a magnet and a Reed Sensor to calculate the current wind speed and to automatically draw the blinds up if the wind speed exceeds a certain level.
