磁性接近传感器, 20.32MM
The is a small cylindrical Firecracker Reed Sensor with hermetically sealed magnetically operated contacts continues to operate long after optical and other technologies fail due to contamination. This sensor operates through non-ferrous materials such as wood, plastic or aluminium. Ideal for battery-powered applications as the contacts do not draw power when in the non-activated state. Well suited for usage in high moisture and contaminated environments and reed contacts last for millions of operating cycles under microcontroller logic level loads.
