Operating Characteristics
 |
When a Reed Switch is actuated by a permanent magnet, the ON-OFF region differs depending on the type and OAT of the switch, and size and power of the Continue reading |
Magnet Information

In general, there are four families of magnets available commercially. Factors such as operating temperature, demagnetizing effects, field strength... Continue reading |
Actuating a Reed Switch
 |
In all systems, magnet and reed switch must be brought to within a specific proximity of each other. This distance will vary in accordance with the se Continue reading |
Reed Switch Lead Formations and Tolerances
 |
Cropping the leads of a reed switch removes low reluctance iron and introduces high reluctance air into the magnetic circuit, much the same as adding Continue reading |
Reed Sensor Contact Protection Circuits
 |
When a reed switch is to be connected to an inductive load or a load where surge current or in-rush current flows (such as a capacitive load or a lamp Continue reading |
Level Sensing Circuits
