Magnetic Reed Sensors for Press Fit Installation 59040 Series
The Littelfuse 59040 series magnetic reed sensors are suitable for position and limit sensing in security systems, industrial equipment, and appliances
Littelfuse 59040 series press-fit reed sensors are small, cylindrical reed sensors 31 mm (1.22 in.) long that press into a 9.5 mm (.375 in.) diameter hole. They offer a choice of normally open, normally closed, or change-over contacts. They are capable of switching up to 200 VDC at 10 W and are available with a range of sensitivity, cable length, plastic housing color (white, black, and wooden brown), and connector options. They have three crush ribs along the length of the capsule that allow a firm and fixed press-fit. The sensors are well suited for position and limit sensing, security, and level sensing applications. These function best with the 57040 actuator.
Note: The 57040 actuator is sold separately.
Features
- Magnetically operated press-fit proximity sensor
- Cylindrical capsule with retaining ribs
- Operates and mounts through nonferrous materials such as wood, plastic, or aluminum
- Hermetically sealed contacts
- Customer-defined sensitivity options available
- Custom cable length and connector options available
- Press-fits into a standard drill size hole of 9.5 mm (.375 in.) diameter
Applications
- Position and limit sensing
- Security
- Appliances
- Industrial
Benefits
- Ribs on capsule compress when inserted into a mounting hole and provide retaining force, allowing simple and secure press-fit installation
- Quick and easy press-fit installation that requires no screws, brackets, nor glue
- 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
