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 sensing range and the sensing object of the retroreective type sensor are specied for the RF-230 reector. The sensing range represents the
actual sensing range of the sensor. The sensing ranges itemized in “A” of the table below may vary depending on the shape of sensing object. Be sure
to check the operation with the actual sensing object.
3) The sensing range and the hysteresis of the diuse reective type sensor are specied for white non-glossy paper (200 × 200 mm
7.874 × 7.874 in) as
the object.
4) If slit masks (optional) are tted, an object of ø0.5 mm
ø0.020 in (using round slit mask) can be detected.
5) Make sure to conrm detection with an actual sensor before use.
