Remove this rubber cap and adjust the potentiometer. 2. Turn the potentiometer counterclockwise until the E2K-C turns off with the sensing object located within the sensing distance. Potentiometer Stop turning the potentiometer at the moment the E2K-C turns off. The sensing distance increases by turning the potentiometer clockwise and decreases by turning the potentiometer counterclockwise. The potentiometer can make 15±3 valid turns and then make slip turns because the potentiometer does not have a stopper. The slip turns will not, however, damage the potentiometer. 1. Slowly turn the potentiometer clockwise until the E2K-C turns on with no sensing object. Potentiometer Stop turning the potentiometer at the moment the E2K-C turns off. 3. The E2K-C will be in stable operation if there is a difference of 1.5 turns or more between the points the E2K-C is turned on and off, otherwise the E2K-C will not be in stable operation. The point the E2K-C turns on. Stable detection if the difference is 1.5 turns or more. The point the E2K-C turns off. 4. Set the potentiometer midway between the two points. The point the E2K-C turns on. Midway The point the E2K-C turns off. 5. If the distance of each sensing object varies, take step 2 with the sensing object located at the farthest sensing distance to be applied. Precautions Correct Use Design Effects of Surrounding Metal During Proximity Sensor installation provide a distance of 80 mm min. from the surrounding metal objects to prevent the Sensor from being affected by metal objects other than the sensing object. If installing the Sensor with the L-shaped mounting bracket, provide a distance of 20 mm min. between the face of the sensing head and the mounting bracket. 20 mm min. 80 mm min. Surrounding conductive object Surrounding conductive object Mutual Interference Space the two Sensors at a distance exceeding 100 mm to prevent mutual interference. Face-to-dace Mounting Parallel Mounting 100 mm min. 100 mm min. 80 mm min. Effect of High-frequency Electro-magnetic Field The E2K-C may malfunction if there is an ultrasonic washer, high-frequency generator, transceiver, or inverter nearby. Sensing surface Be sure to ground Metal 80 mm min. 80 mm min. E-78 Proximity Sensors Sensing Object ∑ Sensing Object Material. The E2K-C can detect almost any type of object. The sensing distance of the E2K-C, however, will vary with the electrical characteristics of the object, such as the conductance and inductance of the object, and the water content and capacity of the object. The maximum sensing distance of E2K-C will be available if the object is made of grounded metal. ∑ Indirect Detection. In the case of the detection of objects in metal containers, each metal container must have a nonmetallic window. Miscellaneous Organic Solvents E2K-C has a case made of heat-resistant ABS resin. Be sure that the case is free from organic solvents or solutions containing organic solvents. Dimensions (Unit: mm) Sensors E2K-C25M## 82 7 Cap cord 13 34 dia.
