This prevents the sensor from being affected by metallic objects other than the target. Also, when using the supplied mounting bracket, be sure to allow a distance of 20 mm or more between the detecting face and the mounting bracket. ## I **MUTUAL INTERFERENCE** To prevent mutual interference, be sure to space the two sensors at a distance greater than that shown in the diagrams. ## **Opposed mounting** **==> picture [165 x 193] intentionally omitted <==** **----- Start of picture text -----**<br> 20 (0.79) 80 (3.15)<br>mm min. mm min.<br>Surrounding<br>conductive<br>object<br>Detecting<br>face<br>Metal<br>To ground<br>Surrounding<br>80 conductive<br>(3.15) object<br>mm<br>min.<br>lo] 80 (3.15) 80 (3.15)<br>mm min. mm min.<br>**----- End of picture text -----**<br> **==> picture [30 x 12] intentionally omitted <==** **----- Start of picture text -----**<br> 100 (3.94)<br>mm min.<br>**----- End of picture text -----**<br> ## **Parallel mounting** **==> picture [82 x 83] intentionally omitted <==** **----- Start of picture text -----**<br> 100 (3.94)<br>mm min. ©<br>**----- End of picture text -----**<br> 6 **E2K-C** **E2K-C** ## I **SENSITIVITY ADJUSTMENT** ## **NO type (E2K-C25M** ❑ **1)** Remove protective rubber plug to gain access to sensitivity adjustment screw. Use the screwdriver provided with each sensor to turn the sensitivity adjustment screw. ## I **USING METAL CONDUIT** If a high voltage of power line runs near the proximity sensor cable, be sure to wire the sensor cable through a metal conduit to protect the sensor from malfunctioning or damage. ## I **SURGE PROTECTION** The proximity sensor is provided with a surge suppressor circuit. However, if any large surge generating source (i.e., motor, welding machine, etc.) exists in the vicinity of the proximity sensor, insert a surge suppressor (such as a varistor) into the surge generating source. - 1) Remove any targets from in front of the sensor. Turn the sensitivity adjustment screw CLOCKWISE until the sensor turns ON and the indicator illuminates. Sensitivity adjustment Stop when the sensor turns ON - 2) Place a target in front of the sensor. Turn the sensitivity adjustment screw COUNTERCLOCKWISE until the sensor turns OFF and the indicator goes out. Note the number of revolutions between OFF and ON positions. Sensitivity adjustment Stop when the sensor turns OFF - 3) If the number of revolutions is greater than one and a half, the sensor will provide stable output. If the number of revolutions is less than one and a half, increase or decrease the distance between the target and the sensing face as necessary to allow at least one and a half revolutions between the ON and OFF positions. 0 1 ON point Stable operation if the difference is more than 1.5 turns © 2 4) Now turn the sensitivity adjustment screw CLOCKWISE to the midpoint between the ON and OFF points. a 1 ON point Set at midpoint 1 between ON and OFF points E ~~G~~ ~ 2 OFF point 5) If the distance between the target and the sensor is not constant, perform the first adjustment operation (#1) when the target is at the closest position to the sensor. Then perform the second adjustment operation (#2) when the target is at the farthest position from the sensor. ## **NC type (E2K-C25M** ❑ **2)** The sensitivity adjustment procedure for NC type proximity sensors is the same as for NO type sensors, with the exception that ON and OFF operations of the proximity sensor and ON and OFF points in the adjustment procedure are exactly reversed. 7 **E2K-C** **E2K-C** ## ~~TT~~ **NOTE: DIMENSIONS ARE SHOWN IN MILLIMETERS.
