M21P Series Magnet


The M21P Series offers a versatile sensor magnet housed for reliable proximity sensing in industrial and commercial applications. Available in two mounting configurations, horizontal slotted screw holes (M21P/1) and vertical slotted screw holes (M21P/2), this series provides flexible installation options to suit various mechanical layouts.
Designed to pair seamlessly with the MK21P, MK21M, and MK21PR Series reed sensors (sold separately), the M21P magnet ensures precise and repeatable actuation. The sensor is mounted on a fixed surface, while the magnet is installed on a moving part, enabling accurate detection of position or motion.
