Notes:
1. Unless otherwise specified, an ambient temperature of +23°C was used for the measurement conditions.
2. It is the value for a standard metal object (iron sheet) under standard environmental conditions.
3. An iron sheet was used for the standard sensing object.
4. Leakage current when the output is in the OFF state.
5. The weight includes the weight of the nuts.
