Littelfuse 59040 series press-fit Firecracker reed sensors are small, cylindrical reed sensors 31 mm (1.22") long that press into a 9.5 mm (.375") diameter hole. They offer a choice of normally open, normally closed, or change-over contacts. They are capable of switching up to 200 VDC at 10 W and are available with a range of sensitivity, cable length, plastic housing color (white, black, and wooden brown), and connector options. They have three crush ribs along the length of the capsule that allow a firm and fixed press-fit. The sensors are well suited for position and limit sensing, security, and level sensing applications. These function best with the 57040 actuator.
