Life Test Data
*Load increase reduces life
expectancy of Reed Switches
& Assembly Instructions
Use proper lead clamping or heat sinking
techniques to prevent mechanical and/or heat
stress during, soldering, and welding
Mechanical shock as the result of dropping the
reed sensor typically from a distance of greater
than 12” may change it’s magnetic sensitivity
and/or destroy the sensor
