A miniature, cylindrical reed sensor with a robust aluminum body 15.24mm x 5.10mm (0.600" x 0.201") with a normally open contact. Capable of switching up to 170Vdc at 10W. Available with a range of sensitivity, cable length and connector options. Well suited for position and limit sensing, security, level sensing and linear actuator applications. Functions best with the 57020 actuator.
Note: The 57020 actuator is sold separately.
- Magnetically-operated proximity sensor with aluminum body
- Operates through non-ferrous materials such as wood, plastic or aluminum
- Hermetically sealed contacts
- Options of normally open, normally closed or single-pole-double-throw
- Customer-defined sensitivity
- Custom cable length and connector options available
- Fits nicely into small, confined spaces
- Quick and easy to install
- Well suited for usage in high-moisture and contaminated environments
- Non-contact solution, aesthetically more appealing than push-button or lever mechanical-type switches
- Ideal for battery-powered applications as the contacts do not draw power when in the non-activated state
- Reed contacts last for millions of operating cycles under micro-controller voltage and current logic-level loads
