These ultra miniature normally closed SMD reed sensors are built with an biasing magnet. 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, Contact Resistance and Variable Contact Resistance before packing. Our products are completely Lead-free and conform to the RoHS directive.
♦ Does not require power for operation ♦ Normally Closed form B contact ♦ Polarity Sensitive ♦ 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♦
This reed sensor is suitable for use in the following applications and in many others: telephone hook switches, fluid tank cap sensing, emergency lamps…

R5B-(Lead Formation Code)-(Release AT Code)
| Formation Code | Lead Formation | RAT Code | *Before |
|---|---|---|---|
| S | SMD | 1 | 5-12 |
| 2 | 10-17 |
* Indicate Release AT band before modification of leads
Example: R5B-S-1
Denotes SMD version in 5 – 12 Release AT.
Non standard lead formations
Dynamic Contact Resistance Limit
Special Release AT Limits
Gold plated leads
As shown in above examples, unlike poles of magnet and sensor cause the sensor to release. Like poles do not cause a release. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one.

The R5B-S 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.
