Accessories
RF-230 (Refl ector): 1 pc.
Notes: 1) Where measurement conditions have not been specifi ed precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) The sensing range and the sensing object of the retrorefl ective type sensor are specified for the RF-230 refl ector. 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.

The sensing range and hysteresis of the diffuse refl ective type sensor are specifi ed for white non-glossy paper (200 × 200 mm 7.874 × 7.874 in) as the object.
4) If slit masks (optional) are fi tted, an object of ø0.5 mm ø0.020 in (using round slit mask) can be detected.
5) Make sure to confi rm detection with an actual sensor before use.
