5 INFORMATI Series Connection and Potentiometer for Adjusting the A multi-rotation potentiometer for adjusting the operating distance is equipped on the back of the main body of capacitance proximity sensors. After the capacitance proximity sensor is installed, use this multi-rotation potentiometer to adjust the operating distance to the standard distance for the grounded metal plate or larger standard target object ( x x 1 t mm) or below the standard distance, according to the usage. If the multirotation potentiometer is turned to the right, the operating distance becomes longer, and if it is turned to the left, the operating distance becomes shorter. Although the potentiometer can be adjusted 1 turns, even if it is turned too much, there will be no damage because the potentiometer turns idly without stopping at that point. Note that, if the operating distance is set more than the rated operating distance, operation becomes unstable. (Except for the -CU-E) Material Characteristics Even if the same material is detected, the operating distance differs by size and shape of the target object. The table below shows examples of how the operating distance differs by the type of material and shape when detected by a capacitance proximity sensor. (Detection distances differ according to the electrical conductivity, relative permittivity and the water absorption state and volume.) Reaction Material Precautions Pay careful attention to the possibility of condensation and freezing of the detector surface and the adhesion of water, oil, and dust to the detector surface because they may cause malfunction. Note that the adherence of fluid material and powder in a non-metal container may cause malfunction. Non-metallic Container Liquid Detection State Three M screws are used for installing the -1-T and -1-N. Ensure that the screws do not penetrate the case more than mm. In the case of a -wire DC proximity sensor, a load with large making current (making current of ma or more, such as a lamp, motor, and solenoid) may deteriorate or damage the switching element. In such case, use the sensor via a relay.
