Safety Precautions EK- Refer to Warranty and Limitations of Liability. WARNING This product is not designed or rated for ensuring safety of persons either directly or indirectly. Do not use it for such purposes. Precautions for Correct Use Do not use this product under ambient conditions that exceed the ratings. Design Ambient Environment The Sensor may malfunction if subjected to water, oil, chemicals, or condensation by falsely detecting these as sensing objects. The EK-1M 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 the 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. l 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 EK- can detect almost any type of object. The sensing distance of the EK-, 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 the EK- will be obtained if the object is made of grounded metal. There are objects that cannot be detected indirectly. Therefore, be sure to test the EK- in a trial operation with the objects before using the EK- in actual applications. Effects of a High-frequency Electromagnetic Field The EK- may malfunction if there is an ultrasonic washer, highfrequency 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 excessive force. Always use washers when tightening the nuts and do not exceed the torque in the following table. d dia. n m * Be sure to ground. Metal object * Be sure to ground the metal object, otherwise Sensor operation will not be stable. Influence of Surrounding Metal (Unit: mm) Dimension l d m n EK-M EK-M 1 EK-1M 1 If a mounting bracket is used, be sure that at least the following distances are maintained. Influence of Surrounding Metal (Unit: mm) Dimension G H EK-M EK-M EK-1M 1 H G Torque EK-M.7 N m EK-M N m EK-1M Note: A special tightening tool is provided with the EK-M@@. Always use this tool to tighten the nuts. Miscellaneous Organic Solvents The Sensor has a case made of heat-resistant ABS resin. Be sure that the case is free from organic solvents or solutions containing organic solvents. Mutual Interference When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.
