e2k-x 5 safety precautions refer to warranty and limitations of liability . this product is not designed or rated for ensuring safety of persons either directly or indirectly. do not use it for such purposes. do not use this product under ambi ent conditions that exceed the ratings. design ambient environment the sensor may malfunction if subject ed to water, oil, chemicals, or condensation by falsely detecti ng these as sensing objects. the e2k-x15m is highly sensitive to inductive objects and can thus be affected even by small quantities of water drops. influence of surrounding objects if the sensor is embedded in metal, maintain at least the following distances between the sensor and t he metal. the sensor is also affected by other materials, such as resins. separate the sensor from other materials by the same distance as for metal. * be sure to ground the metal object, otherwise sensor operation will not be stable. influence of surrounding metal (unit: mm) if a mounting bracket is used, be sure that at least the following distances are maintained. mutual interference when installing sensors fa ce-to-face or side-by-s ide, ensure that the minimum distances given in the following table are maintained. mutual interference (unit: mm) sensing objects the maximum sensing distance will decrease if the sensing object is a non-grounded metal object or dielectric object. ? sensing object material the e2k-x can detect almost any type of object. the sensing distance of the e2k-x, however, wi ll vary with the electrical characteristics of the object, such as the conductance and inductance of the object, and the wa ter content and capacity of the object. the maximum sensing di stance of the e2k-x will be obtained if the object is made of grounded metal. ? there are objects that cannot be det ected indirectly. therefore, be sure to test the e2k-x in a trial operation with the objects before using the e2k-x in actual applications. effects of a high-freque ncy electromagnetic field the e2k-x may malfunction if ther e is an ultrasoni c washer, high- frequency generator, transceiver, or inverter nearby. for major measures, refer to noise of warranty and limitations of liability for photoelectric sensors. mounting do not tighten the nut with excess ive force. always use washers when tightening the nuts and do not exceed the torque in the following table. miscellaneous organic solvents the sensor has a case made of heat-resistant abs resin. be sure that the case is free from organi c solvents or solutions containing organic solvents. warning precautions for correct use model dimension l d m n e2k-x4m 20 50 8 60 e2k-x8m 12 e2k-x15m 10 25 model dimension a b e2k-x4m 80 70 e2k-x8m 150 110 e2k-x15m 300 200 n m d dia. l * be sure to ground. metal object g h influence of surrounding metal (unit: mm) model dimension g h e2k-x4m 20 30 e2k-x8m e2k-x15m 10 a b model torque e2k-x4m 0.78 nm e2k-x8m 2 nm e2k-x15m
