♦ Does not require power for operation ♦ Bi-stable, form E contact remembers state ♦ Sputtered Ruthenium contact ♦ Polarity Sensitive ♦ 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 ♦
These bi-stable reed sensors are built with an inbuilt biasing magnet. As they are molded with pre-flattened leads, no shock is transferred into the device when SMD formation takes place. Various latching/unlatching distances are available depending on the magnet 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.
This reed sensor is suitable for use in the following applications and in many others: floor detection for elevators and lifts, hoists…

R2E-(Lead Formation Code)-(Operate AT Code)
| Formation Code | Lead Formation | OAT Code | Before |
|---|---|---|---|
| S | SMD | 1 | 10-15 |
| F | Low-profile SMD |
Please contact us for Re-closure values.
Operate AT bands indicated above are for unmodified reed switch.
Example: R2E-F-1
Denotes 10-15 Operate AT, Low profile SMD formed.
Non standard lead formations
Special Operate AT and Release AT limits
Gold plated leads
As shown in the examples above, like poles of magnet and sensor cause a latch, and unlike poles, an un-latch. Choosing the right AT band, magnet strength, and operating axis, will restrict the number of operates and releases to one.

The R2E-S and the R2E-F can be tape and reel packed for automatic pick and place, as per IEC-60286-3 norms. 2000 will be packed per spool. 40 – 80g force will be required to peel off cover tape.
