Reed Sensors

Littelfuse Reed Sensors can switch AC or DC loads, making them popular for digital on/off applications. Reed sensors are reed switches that are packaged within an external housing for simplified mounting/connecting and additional protection against environmental influences. Littelfuse Reed Sensors are typically mounted in mechanical systems.
