Sensor Accessories

Contactless speed, position, and liquid level sensors typically depend on actuator magnets that attach to moving parts or float in liquid. Littelfuse produces several kinds of these actuators in a broad range of sizes. We offer powerful neodymium, ceramic, and aluminum–nickel–cobalt (AlNiCo) magnets in a variety of shapes. We can package the actuators with our automotive, industrial, or security sensors, or we can deliver actuators as discrete components. We can also partner with you to design magnets specifically for your applications.
