Notes: 1) Where measurement conditions have not been specied precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) It is the value in state where the circumference of a detection side has a metal object.
3) The maximum operation distance stands for the maximum distance for which the sensor can detect the standard sensing object.
The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient
temperature drift and/or supply voltage uctuation.
4) It is the leakage current when the output is in the OFF state.
5) The weight includes the weight of two nuts.
