Reed switches and magnets

Find out how they work and which magnets can be used with them. Reed sensors when paired with permanent magnets present an ideal method of sensing and detecting movement, proximity, metal detection, and liquid level and flow measurement. Reed switches actuated by magnets are commonly used in mechanical systems as proximity sensors. Both magnets and reed sensors become more magnetic at low temperatures and less magnetic at high temperatures.

The amount of change with temperature depends on the type of magnet and reed switch used.

There are many types and options of reed sensors that are available.

This brief introductory video offers design tips for electronic engineers designing with reed switches.

Sensor capsules may be plastic or . In general, there are four families of magnets available commercially. Factors such as operating temperature, demagnetizing effects, field strength, environmental characteristics, and available space for movement etc. Proximity Switches and Magnets.

Introduction to sensing magnets , with reed switches and hall effect devices. Especially their use with microcontrollers. Low contact resistance and high speed operation.

Suits many applications including sensors, proximity switching instrumentation and al. Screw mounting magnetic switches for general non-contact switching applications. A range of high quality magnetic reed switch sensors and magnets available in nylon and aluminium housings. Window frame reed switch and sash magnet for . The length of the magnet and the length of the reed switch both affect the magnetic field coupling. Removal of the switch lead material reduces the “ magnetic antennae.

The magnetic coupling is reduce the sensitivity is decrease and the magnet must get closer to the reed switch to activate it.
