R3 Miniature SMD Reed Sensor

Indigo color bulletDoes not require power for operation

Indigo color bulletNormally open (NO) form A contact

Indigo color bulletOmni-polar device; actuates with either pole of magnet

Indigo color bulletTwo types of lead configurations

Indigo color bulletThree magnetic sensitivity bands

Indigo color bulletMolded with internal blades parallel to SMD feet

Indigo color bulletPacked in tape and reels conforming to IEC-60286-3 norms

Indigo color bulletRoHS Compliant and Lead-free

 

These miniature SMD reed sensors are designed for low power, high speed switching applications, and have a cost advantage over the standard size SMD reed sensor. As they are molded with pre-flattened lead outs, 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.

Example actuation iconPossible Magnet Actuations

Standard Size 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.

Special iconTape and Reel Dimensions

The R3-S and the R3-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.
