WARNING • Also, mount the Sensor so that it is not aligned with extreme changes in color or materials, as shown below. 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 the product in atmospheres or environments that exceed product ratings. ● Designing Cable The E3S-CL2 uses an oil-resistive cord to ensure oil resistivity. ● Mounting Mounting Direction of movement • Mount the Sensor so that sunlight, fluorescent light, incandescent light, or other strong sources of light do not enter the directional angle of the Sensor. Mounting Direction • Mount the Sensor so that the sensing face runs parallel to the surface of the object being detected as shown below, and not at an angle. Sensing side Precautions • When mounting the Sensor, do not hit the Sensor with a hammer, or the Sensor will lose its watertightness. • Use M4 screws to mount the Sensor. • The tightening torque of each screw must be 1.2 N·m maximum. Surface of sensing object ● Others Oil and Chemical Resistivity (E3S-CL2) The E3S-CL2 was tested for resistance to the oils given in the following table. Refer to the information in the table when deciding which type of oil to use. However, performance may be affected by certain types of oil. If detecting a shiny object, however, mount the Sensor so that the sensing face is at an angle of between 5° and 10° of the surface of the object being detected as shown below, and check to be sure that there is no interference from the background. Test oil classification Product name Kinematic viscosity (mm2/s (cst)) at 40°C Lubricating oil Velocity No.3 (manufactured by Exxon Mobil) 2.02 Water insoluble machining oil Yushiron Oil No. 2 ac (manufactured by Yushiro Chemical Industry Co., Ltd.) Shiny object • If stable operation is not possible near a mirror surface, mount the Sensor at an angle as shown below, and separate the Sensor as far as possible from the mirror surface. Sensing object Mirror surface • Mount the Sensor so that it is not aligned with the direction of movement of the sensing object, as shown below. Water soluble machining oil Direction of movement Sensing object Direction of movement Sensing object Direction of movement pH --Less than 10 Yushiroken EC50T-3 (manufactured by Yushiro Chemical Industry Co., Ltd.) 7 to 9.5 Yushiron Lubic HWC68 (manufactured by Yushiro Chemical Industry Co., Ltd.) 7 to 9.9 Gryton 1700D (manufactured by Toho Chemical Industry Co., Ltd.) Yushiroken S50N (manufactured by Yushiro Chemical Industry Co., Ltd.) Sensing object Direction of movement --7 to 9.2 7 to 9.8 Note: 1. The E3S-CL2 maintained a minimum insulation resistance of 100 MΩ after it was dipped in all the above oils at a temperature of 50°C for 240 hours. 2. When using the E3S-CL2 in environments subject to oils other than those listed above, use the figures for kinematic viscosity and ph values from the table as general guidelines. Additives and other substances contained in oils may affect the E3S-CL2. Be sure to consider this before use. 7 E3S-CL (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
