In the modern electronics world, the reed switch finds applications in almost every equipment and supports the growth in electronics today, which is influenced by constraints like compactness, low power consumption, and functional reliability. A few reed switch and reed sensor applications in the field of electronics and communication are listed below. We have also suggested few of our products for use in each application, but this does not mean that the other products in the same product category will be unsuitable.

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 |
