Handling & 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
Reflow Soldering Conditions according to JEDEC norm
J-STD-020D.1
