|---|---|
| Applicable Amplifiers | SU-7 series |
| Sensing Range | 17 to 23 mm 0.669 to 0.906 in (Convergent point: 20 mm 0.787 in) (Spot size: 1 x 4 mm 0.039 x 0.157 in) Note : The sensing range and the hysteresis of the mark sensor are specified for white non-glossy paper (50 x 50 mm 1.969 x 1.969 in separatedin) as the object. |
| Sensing Object | Min. 0.07 mm 0.003 in width black line on white paper (Note 1) (with 20 mm 0.787 in setting distance and at the optimum sensitivity)(Note 2) Note 1 : The optimum sensitivity stands for the sensitivity level when the operation indicator just lights up in the light received condition.  Note 2 : The minimum sensing object for SH-84R is specified for the case when the sensor detects a black line with respect to the spot as shown below. |
| Hysteresis | 10 % or less of operation distance Note 2 : The sensing range and the hysteresis of the mark sensor are specified for white non-glossy paper (50 x 50 mm 1.969 x 1.969 in separatedin) as the object. |
| Repeatability (Perpendicular to Sensing Axis) | 0.03 mm 0.001 in or less Note : The repeatability for SH-84R is specified for the case when the sensing object approaches the spot sideways as shown below (0.12 mm 0.005 in if it approaches from above or below).  |
