Table 2. SS345PT/SS445P Absolute Maximum Ratings
Note 1: Absolute maximum ratings are the extreme limits that the device will withstand without damage to the device. However, the electrical and
mechanical characteristics are not guaranteed as the maximum limits (above recommended operating conditions) are approached, nor will the
device necessarily operate at absolute maximum ratings.

NOTICE
The magnetic field strength required to cause the switch to change state (operate and
release) will be as specified in the magnetic characteristics. To test the switch against the
specified magnetic characteristics, the switch must be placed in a uniform magnetic field.
