SURFACE MOUNT (SMD)
REED SENSORS
PRODUCT SOLUTIONS
EXCELLENT FOR A VARIETY OF
LOW-POWER OPERATIONS
Based on reed switch technology known for long
life switching for billions of operations, Standex
Electronics environmentally-sealed Surface
Mount (SMD) Reed Sensors can effectively sense
from up to 44 mm while providing a long-lasting,
reliable performance.
Drawing no power in their normally open
contact state, SMD reed sensors are ideally
suited for battery-powered and portable
medical devices.
In addition to a long switching life, these
sensors are also physically robust. Featuring
a unique hermetic seal and no wearing parts,
they can outlast mechanical switches for an
unusually long life in millions of operations.
