MAGNETIC INTERFERENCE
If relays are inserted in close proximity, the pickup and dropout voltages will be affected by the magnetic flux
produced when the coils are energized.
In general, worst-case magnetic interaction conditions for pull-in voltage in a matrix exist when all relay fields
have the same polarity and all of the fields are from adjacent relays (See figure).
The direction of the parameter shift is determined by whether the stray flux aids or bucks the flux produced by the
coil of the relay under consideration.
To calculate the change in pull-in voltage and dropout voltage, multiply the percent change shown by the relay’s
nominal voltage. For example, if the percent change in pull-in voltage is 14% for a 5V nominal relay, the pull-in
voltage will increase by 0.7 volts.
