Note:
The sensitivity has been adjusted so that the maximum sensing range for white non-glossy paper (300 × 300 mm 11.811 × 11.811 in) is 3 m 9.843 ft (1 m 3.281 ft for PX-21 and PX-23ES, 5 m 16.404 ft for PX-26) with the L., C. and R. areas effective. |

- Correlation between external sensitivity adjustment input voltage and sensing range
|
It shows the variation in the sensing range when the external input voltage is changed from 0 to +5 V with the sensitivity adjuster set at the maximum sensing range. |
- Correlation between sensitivity adjuster and sensing range
Please note that due to the adjuster’s characteristics it may be difficult to adjust the sensitivity at a close distance or near to rated sensing distances. (Refer to “Correlation between sensitivity adjustor and sensing range” below.)
