Features
-
In addition to these options, NVE recently introduced a GMR Switch that has provisions
for shutting down an external power transistor in case a short circuit is detected. This is
useful in applications where the finished sensor assembly must be “bulletproof,” or
immune to improper connection.
The following table defines the first digit in the NVE AD part number:
NVE AD
Trigger Field, Direction of Sensitivity, Low Voltage Operation
The second and third numeric digits of the part number NVE ADxxx-xx specify the
magnetic trigger field and direction of sensitivity of the part. Five different magnetic
trigger fields are available for the GMR Switch:
Other magnetic trigger field levels ranging up to 250 Gauss are available on a custom
basis; please contact NVE.
