The sensing range and the sensing object of the retroreflective type sensor are specifi
ed for the RF-230 refl ector (optional). 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.
