Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73 ℉.
2) The sensors with "N" indicated instead of □ in their model Nos. are NPN output type. The sensors with "P" are PNP output 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 fluctuation.
4) When used at a power of 12 V, the product is less susceptible to the effects of internal self-heat generation and therefore a more stable repeat accuracy can be obtained.
5) When the output is 20 mA or less, the product is less susceptible to the effects of internal self-heat generation and therefore a more stable repeat accuracy can be obtained.
6) When the cable length is 2 m 6.562 ft.
7) The response frequency is an average value.
8) The bending-resistant cable type models come with a 0.15 mm2 3-core bending-resistant ø2.9 mm ø0.114 in cabtyre cable.

Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23℃ +73 ℉.
2) The sensors with "N" indicated instead of □ in their model No. are NPN output type. The sensors with "P" are PNP output 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 fluctuation.
4) PNP output, normally closed type models and all NPN output models do not support IO-Link.
5) When the cable length is 2 m 6.562 ft.
6) The response frequency is an average value.
7) The bending-resistant cable type comes with a 0.2 mm2 3-core bending-resistant ø4 mm ø0.157 in cabtyre cable.
8) The bending-resistant cable type comes with a 0.2 mm2 3-core bending-resistant ø6 mm ø0.236 in cabtyre cable.
