NOTES: 3. Inductive loop switching measurement.

4. These parameters must be measured using pulse techniques, tp = 300 µs, duty cycle ≤ 2%.

5. These parameters must be measured using voltage-sensing contacts, separate from the current carrying contacts, and located

within 3.2 mm from the device body.
