Without a sensing object, turn the potention VR to the right and stop at the proximity sensor is ON (OFF). Stop at ON (OFF) position 3. If the difference of the number of potention VR rotation between the ON (OFF) point and the OFF (ON) point is more than 1.5 turns, the sensing operation will be stable. 2. Put the object in right sensing position, turn the potention VR to the left and stop at the proximity sensor is OFF (ON). Stop at OFF(ON) position 4. If it is set in sensitivity adjustment position of potention VR at center between 1 and 2, sensitivity setting will be completed. It is stable when it is over 1.5 turns OFF position (ON position) Adjustment completed OFF position (ON position) ON position (OFF position) ON position (OFF position) ※When there is distance fluctuation between proximity sensor and the target, please adjust 2 at the farthest distance from this unit. ※Turning potention VR toward clockwise, it will be max., or turning toward counter clockwise, it will be min. The number of adjustment should be 15±3 revolution and if it is turned to the right or left excessively, it will not stop, but it idles without breakdown. ※( ) is for Normally closed type. Grounding The sensing distance will be changed by grounding status of capacitive proximity sensor and the target[50×50×1mm(Iron)]. Please check the material when installing the sensor and selecting the target. ● CR18 type ● CR30 type Operating distance (mm) 8 Ground condition OFF 4 Switch a ON OFF ON OFF Switch b ON ON OFF OFF 15 18 6 6 Operating distance (mm) Sensing target ON Sensing target Ground condition (switch b) switch b F-178 switch a switch b Cylindrical, Capacitive type Mutual-Interference & Influence by Surrounding Metals When several proximity sensors are mounted closely, malfunction of sensor may be caused due to mutual interference.

If the bottle for sensing of level is coated by oil etc., it may cause malfunction. Especially, 15mm type has high sensitivity for induced objects, please be careful of waterdrops. Organic solvents Do not let the oil or oil liquid is flowed into the sensor because the case is made by plastic. F-179
