New to Reed Switches or Reed Sensors? This Help and Support section gives detailed information and Usage Notes on using Reed Switches, Reed Sensors, and Magnet Sensors. Usage Notes cover Ampere-Turn selection, Effects of Temperature on Reed Switches and Reed Sensors, Precautions on forming Leads, Reflow and Manual Soldering, High current and Ultrasonic Welding, Potting and Encapsulation, and Magnet Selection. More Reed Switch Help topics such as Magnet Operating Characteristics, and types of magnets for various applications are also covered. A contact protection lists simple circuits that protect and extend the life of Reed Switches when used in applications having inductive, capacitive or light bulb loads. A glossary section with meanings to the most widely used reed switch related terms is also available.
