Notes: 1) Where measurement conditions have not been specifi ed precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) “ I ” in the model No. indicates a different frequency type.
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 fl uctuation.
