Oil-resistive, long-distance photoelectric sensor (metal case) E3S-C Achieves excellent water/oil-resistance and long-distance detection. Features Meets IP67 tough standard water/oil resistance Lineup of M12 metal connector joint type models E3S-C meets the IP67 requirements of the IEC standards and 6P of the NEMA standards. E3S-C can be used worry-free in automotive assembly lines and other production lines where oil vapor exists. It can also be applied to food processing lines because it resists hydrogen peroxide, detergent and potassium hydroxide. Lineup of water/oil/shock-resistant M12 metal connector joint type models are available. This series ensures ease of sensor replacement during maintenance. Sensing distance is six times longer than that of conventional OMRON photoelectric sensor The sensing distance of the E3S-C is six times longer than that of the conventional, metal case type OMRON photoelectric sensor. The through-beam, retrorefletive (with M.S.R. function) and diffuse reflective models have sensing distances of 30, 3 and 2 meters, respectively. Through-beam Model 5m E3S-5E4 Retroreflective Model 2 m (non-polarized) E3S-R2E4 Diffuse Reflective Model 300mm E3S-DS30E4 30m 3 m (polarized) 2m Excellent shock resistance of 1,000 m/s2 The industry's top-class photoelectric sensor features shock resistance of 1,000 m/s2, which is as high as that of a proximity sensor at rated values, and vibration resistance of as high as 10 to 2,000 Hz. The E3S-C can be used worry-free in metal processing, conveyor and other lines. A-146 NPN/PNP output selector The operation panel has the NPN/PNP output selector. You need not prepare two NPN and PNP models for export. You need not worry about malfunctions due to noise, either. Mutual interference PAT in the First stry Pending Indu prevention enhanced (Retroreflective, diffuse reflective models) Fuzzy inference is introduced into the mutual interference prevention for the first time in the industry. This prevents a malfunction due to mutual interference, enabling two sensors to be mounted closely side by side. Easy optical axis alignment OMRON's original "automatic position compensation system" minimizes misalignment of mechanical and optical axes to merely ±2°. The optical axis is aligned perfectly by only installing the sensor. Photoelectric Sensors Application Detection of engine block E3S-C Drill breakage detection IP67 ensures a worry-free use in oil mist environment.

Model Operation Sensitivity adjustment (diffuse reflective model, light-ON) Photoelectric Sensor Sensing object Photoelectric Sensor B Point B Sensitivity adjuster Sensing object A Point A Detection state Background Sequence Indicator state ONÆOFF Stability indicator Light indicator (green) (red) ONÆOFF ONÆOFF Stability indicator Light indicator (green) (red) ON C Setting OFFÆON ON´OFF --Stability indicator Light indicator (green) (red) Adjustment procedure Place a sensing object in the predetermined position, turn the sensitivity adjuster clockwise (increase sensitivity) until the incident indicator (red) is turned ON, and define this position as (A). Remove the sensing object, turn the sensitivity adjuster further clockwise until the incident indicator (red) is turned ON by a background object, and define this position as (B). Turn the sensitivity adjuster counterclockwise (decrease sensitivity) from (B) until the incident indicator (red) is turned OFF, and define this position as (C). When there is no background object, define the maximum adjuster position (Max) as (C). Set the adjuster in the middle of positions (A) and (C) (optimum sensitivity setting). Also make sure that the stability indicator (green) is turned ON when there is an object and when there is no object. When the indicator is not turned ON, recheck the detection method since there is a little allowance. Unlike the conventional models, the E3S-C scarcely has sensitivity variations between products. Therefore, you need to make the above adjustment on only one diffuse reflective model of E3S-CD that will be used for detection under the same conditions, and match the indicator points of the other diffuse reflective models of E3S-CD with the above adjusted one. (You need not match the sensitivity of each sensor.) E3S-C A-151 Precautions Correct Use Design Fuzzy mutual interference prevention When reflective photoelectric sensors are installed side by side, one sensor may receive the light from the other sensor, which may disturb the incident signal, causing a malfunction. The fuzzy mutual interference prevention monitors interfering light for a predetermined period of time before light is emitted, and imports the interfering light level and incident frequencies as data. Using these values, fuzzy inference is made to find the risk of malfunction to control the light emitting timing, reducing the risk. (Direct installation) Install the E3S-C as shown below. [M4 screwing] Two, 4.5 dia. through holes M4 M4 hole M4 hole [M3 screwing] (When risk is low) Light is emitted after interfering light is gone. 2-M3 Light interference M4 hole Emission pattern (When risk is high) Light is emitted after shifting to a gap of interfering light. Light interference Emission pattern Wiring Considerations Cable • An oil-resistance cable is used to ensure oil resistance. • The bending radius should be 25 mm or more. Installation Sensor installation • Note that during the E35-C installation, hammering it will damage the water resistance function. • Use an M4 screw, tightened to a torque of no more than 1.18 Nm. M4 hole M3 Optical axis adjustment (Optical axis locking holes) By fitting screws into the optical axis locking holes, the mounting bracket is set onto the mounting shaft of the mounting bracket. For adjustment Optical axis Four M4 optical axis lock holes Mounting axis (When using the mounting bracket) • To set the sensor on the mechanical axis, use the optical axis locking holes. • When the sensor cannot be set on the mechanical axis, move the E3S-C vertically and/or horizontally and set it in the center of the area where the incident indicator is turned ON. Make sure that the stability indicator is ON. A-152 Photoelectric Sensors Lens in use. The slit must be on this side. Lens in use. Miscellaneous Oil resistance/chemical resistance • Though E3S-C has a high oil resistance, it may not be able to exhibit its performance depending on the oil type. Use oil in compliance with the following table. • Regarding the oil resistance of E3S-C, it has passed tests on the oils given in the following table. Refer to the table for examining the oil to be used.

For use in the environment where the E3S-C is exposed to the oil other than those in the above table, use the dynamic viscosity and PH in the above table. Pre-examine the oils since the sensor may be affected by additives and like in the oils.
