Reed Switch Precautions
How to handle reed switches, how to modify, cut or form reed switch terminals or leads.
Reed Switches Used with Permanent Magnets
How reed switches behave in a magnetic field emanating from a permanent magnet. How different magnet and reed switch orientations are used in proximity sensors.
Reed Switch Ampere Turns (AT) vs. Milli-Tesla
Ampere turns is a common way to measure reed switch sensitivity. Milli-Tesla is an alternate measure.
Reed Switch as a Proximity Sensor
Reed switches close and open when interacting with a magnetic field. Understand how this interaction can be structured to create motion sensors, proximity sensors, pressure sensors, fluid level sensors, rotation sensors and a host of other applications.
Reed Switch used in a Relay
Inductive coils can be used to introduce a magnetic field to actuate a reed switch. Understand how a coil and a reed switch combine to create relays for a multitude of applications.
