With more than 40 years of expertise in the magnetic sensors technology, celduc relais is the leading expert in the manufacturing of 100% Made in France magnetic sensors. Celduc relais offers several ranges of sensors using different technologies. Today we will talk about REED switch sensors. But first, for which purpose are magnetic sensors used?
The functions of magnetic sensors are various:
Magnetic sensors are used to monitor or control a level, a passage, a movement, a position, a speed … .
Their functions and uses have no limits except the imagination of the user.
The applications of our sensors are also numerous. They can be used in many domestic appliances but also in industry : automotive, aircraft, telecom and also for automation …
Our sensors are also used in buildings.
A magnetic sensor is made of a REED switch that reacts to a magnetic field. A magnet is used to control the sensor.
The REED switch consists of two or three ferromagnetic flexible metal contacts in a hermetically sealed glass envelope, filled with an inert gas, which will come into contact under the influence of a magnetic field.
A REED detector is a magnetically activated omnipolar switch. This means that a magnet can approach it from any angle, with any pole. Many configurations are possible, the most common being parallel and perpendicular approach.
AC and DC switching
No power supply required
Can operate in harsh environments
Extensive sensing range (depending on the magnetic sensitivity of the switch, the power of
the magnet as well as the magnetic environment),
Long service life
Here is a selection of REED Switch sensors.
Operation: A float equipped with one or more magnets moves with the fluid and activates a hermetically sealed REED contact thanks to its magnetic field.
celduc relais offers a wide range of position/presence sensors which are general purpose sensors for industrial and domestic applications (rebate sensors, door opening, presence of protective covers, white goods, …). They are characterized by their fixing methods which are either screw or tubular.
At celduc relais 50% of our sensors are made according to our customers’ specifications. So if you have a new project, contact us, we will bring you an adapted solution
