Safety Precautions 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 the product in atmospheres or environments that exceed product ratings. ● Designing Fuzzy Mutual Interference Prevention Function If Reflective Sensors are installed side by side, each Sensor may be influenced by the light emitted from the other Sensors. The fuzzy mutual interference prevention function of the E3S-C enables the E3S-C to monitor any light interference for a certain period before the E3S-C starts emitting light so that the E3S-C can retrieve the intensity and frequency of the light interference as data. Using this data, the E3S-C estimates with fuzzy inference the risk of the malfunctioning of the E3S-C and controls the timing of the E3SC’s light emission. Mounting Bracket • When mounting the E3S-C with the mounting bracket so that sensing objects will be in the direction of the mechanical axis, use the optical axis lock holes. • If it is not possible to mount the E3S-C so that the sensing objects will be in the direction the mechanical axis, move the E3S-C upwards, downwards, to the left, or to the right and secure the E3SC in the center of the range where the light indicator will be lit, at which time make sure that the stability indicator is lit. Direct Mounting Mount the E3S-C as shown in the following illustration. Mounting with M4 Screws Two, 4.5 dia. through holes M4 M4 hole M4 hole Mounting with M3 Screws When the risk is low: The E3S-C waits until there is no light interference and emits light. Two, M3 Light interference Emission pattern M4 hole When the risk is high: The E3S-C emits light between each period of light interference. Light interference Emission pattern ● Wiring Cable • The E3S-C uses an oil-resistive cable to ensure oil resistivity. • Do not allow the cable to be bent to a radius of less than 25 mm. M4 hole M3 Optical Axis Adjustment Optical Lock Holes By inserting screws into the optical axis lock holes, the Mounting Bracket will be in the direction of the optical axis of the E3S-C. Optical axis Mounting axis Fur optical o axis lock holes (M4) ● Mounting Mounting • When mounting the E3S-C, do not hit the E3S-C with a hammer, or the E3S-C will loose watertightness. • Use M4 screws to mount the E3S-C. The tightening torque of each screw must be 1.18 N·m maximum. 6 E3S-C ● Adjusting Optical Axis of Through-beam Sensor The E3S-C Through-beam Models incorporates two lenses, one of which will be used as shown in the following illustration. When using a Slit, the Slit must be on the side where the lens to be used is located. Horizontal Model Vertical Model Lens in use. The Slit must be on this side. Lens in use. ● Others Oil and Chemical Resistance • Although the E3S-C is oil-resistance, refer to the following table before using the E3S-C in places where oil may be sprayed on the E3S-C. • Tests were carried out with the following oils and it was certified that the E3S-C resists these oils. Oil Lubricating oil Water insoluble machining oil Unused lens Unused lens Water soluble machining oil Product name Kinematic viscosity (mm2/s (cst)) at 40°C Velocite No.3 2.02 Yushiron Oil No. 2 ac Less than 10 To ensure the water resistance of the E3S-C, tighten the screws of the operation panel cover to a torque of 0.34 N·m to 0.54 N·m. --- Yushiroken EC50T-3 7 to 9.5 Yushiron Lubic HWC68 7 to 9.9 Griton 1700D Yushiroken S50N Water Resistance PH --- 7 to 9.2 7 to 9.8 Note: 1. The E3S-C maintained a minimum insulation resistance of 100 MΩ after the E3S-C was dipped in all the above oils at a temperature of 50°C for 240 hours. 2. When using the E3S-C in a place where an oil other than the ones listed above is sprayed on the E3S-C, refer to the above kinematic viscosity and ph values. The location may be suitable for the E3S-C if the kinematic viscosity and pH values of the oil are close to the above kinematic viscosity and pH values, but make sure that the oil does not contain any additive that may have a negative influence on the E3S-C. 7 E3S-C (Unit: mm) Dimensions Tolerance class IT16 applies to dimensions in this datasheet unless otherwise specified.
