A miniature overmolded reed sensor 16.00mm x 2.40mm x 2.40mm (0.630" x 0.094" x 0.094") with straight or gull-wing leads. Provided with normally open contacts. Capable of switching up to
200Vdc at 10W. Its package contains molded stand-offs to allow board washing. Available with a range of sensitivity options, including customer-defined sensitivity. Well suited for position and limit sensing, security, and door/window alarm systems. Functions best with the 57045 actuator.
Note: The 57045 actuator is sold separately.

Applications:
Reed switches and sensors are highly effective solutions for flow sensing applications that can be used for detecting the presence of fluid flow in a system or even measure the rate of fluid flow.
A most integral appliance in any home is a washing machine. Washing machines have helped made the chore of cleaning clothes quite effortless.
The position sensing lid lock ensures that the lid is securely locked in place.

When there is significant capacitance in a reed sensor reed relay or reed switch circuit the peak current and energy switched by the reed contacts should be considered.
Reed Switch Terms Glossary
Littelfuse reed switches are normally specified to operate in a temperature range of -40 �C to +125 �C. T
When used within their capabilities Littelfuse reed sensors reed relays and reed switches provide many years of robust performance
When a reed switch or reed sensor is used to control an inductive device (relay coil solenoid transformer small motor etc.)
The purpose of this application note is to document the preferred method of reading the sensitivity and contact resistance of Littelfuse reed switches.
When cutting and forming reed switch leads it is important to use the correct support and cutting tools to avoid causing damage to the glass-to-metal hermetic seals.
Although a reed switch can be activated by placing it inside an electrical coil many reed switches and reed sensors are used for proximity sensing and are activated by a magnet.
The maximum shock specifications in the Littelfuse catalog are very conservative for most switches smaller than the DRxxxx type. T
This application note applies to all of Littelfuse�s products that are normally soldered to printed circuit boards (PCBs) including all reed switches.
The data sheets for Littelfuse parts show temperature ranges for storage. However long term exposure to extreme temperatures in the specified storage temperature range may degrade solderability of terminals.
Littelfuse tests sinusoidal vibration according to Mil. Std. 202G Method 204D Test Condition G (10 � 2000 Hz frequency sweep at 30 G or 0.06 inch double amplitude whichever is less).
