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
