Reed switches in Barcode Scanners
|
A reed switch and magnet combination is used in the docks and barcode scanners, and whenever a scanner is removed from a dock to conduct a manual scan, the signal from the reed switch is used to ensure that the belt does not index. Continue reading |
Reed sensor in Contact protection
|
Most reed switch and reed sensor based products require contact protection when used with loads where there is a chance of inrush current. More details about contact circuits are available here. A reed sensor with a built-in resistor… Continue reading |
Magnet sensors in Satellite dish position sensing
|
While tuning motorized dishes, the dish motor is turned until a clear signal is received and a reed sensor is locked there. Different channels are beamed from different satellites and reed sensors are used to remember the positions… Continue reading |
Reed sensors in weather proof electronic equipment
|
In weather proof walkmans, cellular phones, and CD players, conventional switches cannot be used because they are not water proof or dirt and dust proof. Hermetically sealed reed sensors are the ideal solution as they can be mounted inside the equipment… Continue reading |
Reed sensors in Cellular phone, Notebook computer and PC desktops
|
In mobile devices with doors to protect the keypads, the power to the display or central processing unit (CPU) can conveniently be switched on or off, just by opening or closing the doors… Continue reading |
Reed switches and Reed sensors in On/off switch in Microphones and Radio transmitters
|
In microphones and radio transmitters, unnecessary signal transients and speaker crackle can be avoided at the time of switching on or off, by using a reed sensor based on/off switch. The reed sensor is mounted on a small PCB inside the microphone… Continue reading |
Reed sensors in Telephone Handsets
|
Modern telephone circuitry loads can easily be switched by reed sensors. Conventional hook switches which are used in telephones undergo millions of operations and fail easily. When a reed sensor is used in the place of a hook switch, it can survive millions of operations… Continue reading |
Magnet sensors for Tension Monitoring in Coil Winders
|
Reed Sensors find an important role in closed loop tension control systems like coil winders, tape and reel machines etc. The wire, which is to be wound, is usually taken through a spring, which gives cushioning when winding on bobbins, which are not circular. A reed sensor mounted near this spring… Continue reading |
Reed switches in Relays for Fax Machines
|
Ultra miniature relays are manufactured by winding coils around reed switches and can be used to switch high loads with very low input voltages. Reed relays are extensively used in a number of… Continue reading |
Reed switches for Door sensing on Copiers and Scanners
|
In copiers and flatbed scanners, reed sensors are used to signal the main processor if the top door is left open. This prevents wastage of toner in copiers and helps build a closed loop system which can automatically start the scanning or copying cycle when the door is closed… Continue reading |
