Highlights

Does not require power for operation  Normally Open Form A contact Sputtered Ruthenium contact  Omni-polar device; actuates with either pole of magnet  Two types of lead configurations  Molded with internal blades parallel to SMD feet  Packed in tape and reels conforming to IEC-60286-3 norms  RoHS Compliant and Lead-free  Not Sensitive to ESD

Description

These R5 ultra-miniature SMD reed sensors are designed for signal switching applications and have a size advantage over the standard size SMD reed sensor. As they are molded with pre-flattened leads, no shock is transferred into the device when SMD formation takes place. Various activating distances are available depending on the magnet and the AT band used. The sensors are tested 100% for Operate AT, Release AT, Static Contact Resistance and Variable Contact Resistance before packing. Our products are completely Lead-free and conform to the RoHS directive.

Applications

This reed sensor is suitable for use in the following applications and in many others: cellular phones and PDAs,  dentists drills,  pacemakers and defibrillatorsnerve stimulatorsspirometers, lightsabers, exhaust emission sensinglevel sensors

Possible magnet actuations

Ultra-miniature Reed Sensor Magnet Actuation Examples

A few examples of magnet actuation are shown above. Being an omnipolar device, this sensor can be actuated with either a north pole or a south pole or both. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one. Click here to view actuation distances of this sensor with the standard magnets.

SMD Soldering Procedure

Tape and Reel Dimensions

The R5-S and the R5-J can be tape and reel packed for automatic pick and place, as per IEC-60286-3 norms. 2500 will be packed per spool. 40 – 80g force will be required to peel off cover tape.
