Reed Switch Sensor Circuit Board

Reed switches and reed sensors are used along with resistors or special reed sensors with integrated resistor to give out a potentiometric feed back across two outputs as a foamed magnetic float moves along the pcb s length.

Reed switch sensor circuit board.

Automatic points switch in this application the mr204 is used to control a point motor automatically. They are made from 2 ferrous reeds positioned so that they are not touching. Reed switches are a perfect trick for non contact activation applications. Do you need non contact switching within your project.

Or you can hook a large door specific reed switch up to a blynk board and have it send push notifications to your phone when the door state changes. Then you may consider this sensor. A printed circuit board pcb mechanically supports and electrically connects electrical or electronic components using conductive tracks pads and other features etched from one or more sheet layers of copper laminated onto and or between sheet layers of a non conductive substrate. Refurbished dell h7prc circuit boards dell oem inspiron 15r n5110 reed switch sensor circuit board h7 laptops.

Once the magnet is brought near the vicinity of the circuit it will turn on and the led will be powered on. A reed switch is same like an electrical mechanical switch the only difference is it is operated by magnetic field. The pcb tracks can be designed in such a way that a full tank gives high resistance and an empty tank gives low resistance or vice versa. Components are generally soldered onto the pcb to both electrically connect and mechanically fasten them to it.

We used a reed switch to detect when the doors of this tardis themed music box opened. In mechanical switches contacts are made by pressing the switch with finger but in reed switch contacts are made by exposing magnetic field to switch. The reed switch circuit we will build is shown below. Well this is all done with a small sensor known as contact switch or reed switch.

These packages offer resistance to mechanical stress by protecting the bare glass of the reed switch.

The mr204 is controlled by 2 reed switches sensor 1 sensor2 this means the locomotive requires a magnet fixed to the underside of the unit to activate the sensors. Reed switch 2 x 14 mm normally open 10pcs.

A reed switch is an electromagnetic switch that controls the flow of electricity in a circuit. However for an application such as a door security sensor the reed switch needs a protective shell housing for handling and mounting. This can be used on systems where the fiddle yard is feeding into a main line. A bare reed switch can easily be mounted on circuit boards.

This above circuit built on a breadboard is shown below.
