7 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 ambient conditions that exceed the ratings. Design Influence of Surrounding Metal When mounting a Proximity Sensor, be sure to provide a distance of 8 mm min. from surrounding metal s to prevent the Sensor from being affected by metal s other than the sensing. When mounting the Sensor with the L-shaped Mounting Bracket, be sure to provide a distance of 2 mm min. between the face of the sensing head and the Mounting Bracket. Be sure to ground. WRNING Precautions for Correct Use 2 mm min. 8 mm min. surface Metal Surrounding conductive s 8 mm min. 8 mm min. 8 mm min. Surrounding conductive s Mutual Interference When installing Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. Effects of a High-frequency Electromagnetic Field The may malfunction if there is an ultrasonic washer, highfrequency generator, transceiver, portable telephone or inverter nearby. For major measures, refer to Noise of Warranty and Limitations of Liability for Photoelectric Sensors. Objects Object Material The can detect almost any type of. The sensing distance of the, however, will vary with the electrical characteristics of the, such as the conductance and inductance of the, and the water content and capacity of the. The maximum sensing distance of the will be obtained if the is made of grounded metal. Indirect Detection To detect s in metal containers, each metal container must have a nonmetallic window. Power Conditions is enabled within 2 ms for the 2M@@. Design the system so that the power for the Sensor is turned before the power for the load. Miscellaneous Organic Solvents The Sensor has a case made of heat-resistant BS resin or PBT resin. Be sure that the case is free from organic solvents or solutions containing organic solvents.
