Life Test Data
Handling & Assembly Instructions
*Load increase reduces life expectancy of Reed Switches
Fixing of the leads before modification (bending, cutting, sol-
dering) recommended to prevent tensions on the glass body
Mechanical shock impacts (drop down) may change the
sensitivity or destroy the Switch
Sensitivity changes due to modification
Mechanical stress needs to get prevented
Series resistor recommended for >5m cable length
