Reed Relays

What are Reed Relays?

A reed relay is a piece of equipment that makes use of an electromagnet to monitor one or multiple reed switches. The connections are made of magnetic materials, and electromagnetics does work directly on reed relays without the need for an armature to move reed relays. Sealed in a long, confined by the glass tube, the connections are secured from corrosion. The glass container may consist of many reed switches that can be placed into a standalone bobbin and activated simultaneously.

Typical applications

Reed relays have still been utilized even outside of the telephone industry. Due to their hermetic seal, quick operation time, prolonged life of 109 operations, and very constant contact performance, reed relays have continued to be used in applications beyond the telephone sector, such as automatic test equipment and electronic instruments.

Reed relays have also been extensively used in RF and microwave switching applications. They are also employed in circuits like photomultiplier detectors and other extremely low current handling circuits because of their extremely low leakage current (in the order of femtoamperes).

How are reed switch sensors actuated?

It is made up of two contacts on ferrous metal reeds enclosed in an airtight glass container. Normally, the connections are open and not electrically connected. Bring a magnet close to the switch to activate (close) it. The reed switch will return to its initial position once the magnet is removed.

How does a reed switch work?

Many reed switches and reed sensors are used for proximity sensing and are triggered by a magnet, even though a reed switch may be activated by putting it within an electrical coil. The gadget turns on as soon as the magnet is placed close to the reed sensor/switch.
