Accessories
–
Nut: 2 pcs., Toothed lock washer: 1 pc.
Notes: 1) Where measurement conditions have not been specied precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
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 uctuation.
3) It is the leakage current when the output is in the OFF state.
4) The maximum load current varies depending on the ambient temperature. Refer to “I/O CIRCUIT AND WIRING DIAGRAMS” for more details.
5) When the cable is extended, the residual voltage becomes larger.
6) The weight of the threaded type includes the weight of two nuts and one toothed lock washer.
