59040 Series - Firecracker Reed Sensor with Retaining Ribs
DataSheet:Littelfuse Reed Switches 59040 datasheet
The 59040 Press-Fit Firecracker Reed Sensor is a small, cylindrical reed sensor 31.0mm (1.22”) long that presses into a 9.5mm (.375”) diameter hole with a choice of normally open, normally closed or change-over contacts. Capable of switching up to 200Vdc at 10W. Available with a range of sensitivity, cable length, plastic housing color, and connector options. Well suited for position and limit sensing, security, and level sensing applications. Functions best with the 57040 actuator.
Note: The 57040 actuator is sold separately.
Features:
Benefits:
Applications:- Magnetically-operated proximity sensor
- Cylindrical capsule with retaining ribs
- Operates through non-ferrous materials such as wood, plastic or aluminum
- Hermetically sealed contacts
- Customer-defined sensitivity
- Press-fits into a standard drill size hole of 9.5mm (.375”) diameter
- Quick and easy press-fit installation that requires no screws, brackets, nor glue.
- Ribs on capsule compress when inserted into a mounting hole and provide retaining force, allowing simple and secure press-fit installation.
- 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
- Position and limit switching
- Security
- Level sensing
- Industrial
