Benefits of Reed Sensors

What are the benefits of Reed Sensors?

Reed Sensors have been used as a successful switching and sensing technology for many years. Utilised across a broad range of applications, we look at some of the key benefits of the reed sensor:

Non-touch switching solution − the sensors are embedded within a device offering better protection. They are less prone to damage as there is no physical interaction with the switch.

Easy to assemble and position within an application. There are various assembly options available including snap fit, flatpack and through hole.

Robust and reliable − reed sensors are encased, protecting the internal reed switch. They are IP67 rated and hermetically sealed making them highly suitable for hazardous and demanding environments.

Low mechanical wear − because this is a non-touch switching technology, reed sensors have extremely low mechanical wear. Therefore, they have a very long operational life which in turn makes them an economical choice.

Highly Efficient − a magnet changes the state of the reed switch so there is no power consumption. They have a much lower power consumption than other electronic switch options.

Various Magnetic Sensitivity Ranges − no two designs are the same so it is important the right sensitivity is selected for particular applications. An example of standard AT or pull in ranges are listed below:
1 = 10 to 15 AT
2 = 15 to 20 AT
3 = 20 to 25 AT

AT refers to Ampere Turns which is a standard unit categorising the magnetic sensitivity of a sensor.

Highly Customisable − the challenges of individual designs mean that standard sensors may not be suitable. An important benefit of reed sensors is that they can be customised in a variety of ways.

Customer-specific modifications include the choice of cable length and colour, the attachment of terminals or connectors, the use of special materials (e.g. for a higher temperature range) or the complete design and manufacture of individual Sensor housings.

As we have seen, there are many benefits of Reed Sensors. They offer a versatile and economic switching solution, suitable for a wide variety of applications. Alan Butcher Components supplies reed sensors manufactured by PIC GmbH, a highly respected producer of sensor products.
