59022 Series - Firecracker Reed Sensor
DataSheet:Littelfuse Reed Sensors 59022 datasheet
A small, cylindrical reed sensor 25.4mm (L) x 5.80mm (Dia.) (1.00" x 0.228") with a choice of normally open, normally closed or change-over contacts. Capable of switching up to 300Vdc 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 57022 actuator.
Note: The 57022 actuator is sold separately.
Features:
- Magnetically-operated proximity sensor
- 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
Benefits:
- 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
Applications:
- Position and limit switching
- Security
- Level sensing
- Linear actuators
