Sensor & Relay Magnets

Sensor and Relay Magnet Info

Our selection of magnets for sensors and relays offer a number of different sizes, shapes and grades to fit many sensor applications. Small rare earth neodymium magnets like these are often used to activate reed switches, hall effect sensors and a variety of other magnetic switches, sensors, relays, pickups, probes, encoders, etc. Learn more in our Reed Switches and Hall Effect Sensors article and check out some of our DIY articles like Brushless DC Motor, Raspberry Pi Alarm System, or Make a Magnetometer to see where and how magnets are used in reed switches, hall effect sensors and other sensors and relays.

What does a magnet do to a sensor? - Magnets have different effects on different types of sensors. We explain how a reed switch and hall effect sensor work in our Reed Switches and Hall Effect Sensors article.
