干簧开关, 59025系列, 圆柱形, 20 mm, SPST-常闭, 5 W, 175 Vdc, 0.25 A, 15至20 AT
The is a 20mm Firecracker Reed Sensor with tinned leads terminals. This sensor is a small cylindrical reed sensor with a choice of normally closed contacts. Operates through non-ferrous plastic material. Well suited for usage in high moisture and contaminated environments. Non-contact solution, aesthetically more appealing than push-button or lever mechanical-type switches. Reed contacts last for millions of operating cycles under microcontroller logic level loads. Ideal for battery-powered applications as the contacts do not draw power when in the non-activated state. Suitable for position and limit sensing, linear actuators, security and level sensing applications.
