Littelfuse (Chicago, IL) has released the 59040 Series press-fit reed sensor. No screws, brackets, or attachment accessories are needed for installation. The magnetically operated Firecracker sensor press-fits securely into a 3/8" (9.5 mm) diameter hole.

The sensor is designed for mounting on a fixed frame; the magnet actuator is positioned on a moving surface or door. The 59040 Series reed sensor offers switching capability up to 200VDC/140VAC at 10 W/VA. A range of sensitivity and cable length options are available.

The component operates through nonferrous materials such as wood, plastic, or aluminum. Hermetically sealed reed contacts last for millions of operating cycles, under microcontroller voltage and current logic-level loads.
