AccessoriesNut: 2 pcs., Toothed lock washer: 1 pc.

Note 1 : Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.

Note 2 : 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 fluctuation.

Note 3 : The repeatability is given for the stable sensing range. (along sensing axis, perpendicular to sensing axis)

Note 4 : If the cable of the sensor head is cut or extended, the sensing range and the hysteresis change.

Note 5 : The weight of the threaded type includes the weight of two nuts and one toothed lock washer.
