Firecracker Sensors

Littelfuse Firecracker Sensors feature a slim cylindrical package that is suitable for mounting on a frame. These reed sensors offer engineers a choice of normally open, normally closed, or change-over contacts configurations. Littelfuse Firecracker Sensors are ideal for position and limit sensing, security, level sensing, and linear actuator applications. Each sensor has a corresponding actuator (sold separately).
