▣Installation and sensitivity adjustment
Please supply the power to the sensor after installing the emitter and the receiver in face to face, and then
adjust an optical axis and the sensitivity as follow;
〈BUD-30S , BUD-50S 〉
Detecting position B Optional position

※Since the case of BUD series is a metal part, it should be grounded not to
MIN MAX occure electric static and noise.
