♦ Does not require power for operation ♦ Normally Open Form A contact ♦ Sputtered Ruthenium contact ♦ Omni-polar device; actuates with either pole of magnet ♦ Three types of lead configurations ♦ Three magnetic sensitivity bands ♦ 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 ♦
These R2 standard size SMD reed sensors are designed for carrying moderate current and have an SMD pitch which is slightly wider than the miniature 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 and release AT, Contact Resistance and Variable Contact Resistance before packing. Our products are completely Lead-free and conform to the RoHS directive.
This reed sensor is suitable for use in the following applications and in many others: cellular phones and PDAs, weather proof electronics, fluid tank cap sensing, hands free kits…

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.
The R2-S and the R2-F 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.
