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 E3S-C's light emission. When the risk is low: The E3S-C waits until there is no light interference and emits light. Light interference Emission pattern When the risk is high: The E3S-C emits light between each light interference moment. Light interference Emission pattern Sensitivity Adjustment (Reflective Sensors) Position A Sensitivity adjustor Position B Sensing object Photoelectric sensor Setting --- Photoelectric sensor Sensing object Item Sensing condition A A C C B Min. Indicators OFF ON STABILITY (green) Procedure Max. LIGHT (red) Locate a sensing object at the sensing distance, set the sensitivity adjustor to the minimum scale position, and gradually increase sensitivity by turning the sensitivity adjustor clockwise until the incident light indicator (red LED) is ON. Position A is where the indicator has turned ON. Regard the maximum scale position as Position A if the indicator does not turned ON at full sensitivity. Min. OFF Min. Max. OFF OFF STABILITY (green) LIGHT (red) Remove the sensing object and turn the sensitivity adjustor clockwise until the E3S-C detects the background object and the incident light indicator (red LED) is lit. The moment the red light indicator is lit, stop turning the sensitivity adjustor, the position of which is point B. Turn the sensitivity adjustor counterclockwise to decrease the sensitivity until the red light indicator is OFF. The moment the red light indicator is OFF, stop turning the sensitivity adjustor, the position of which is point C. If there is no background object, point C is where the sensitivity adjustor is set to maximum. Max. ON STABILITY (green) LIGHT (red) Set the sensitivity indicator to the position between Positions A and C (in some cases, Positions A and C are opposite of the above example). The photoelectric sensor will then work normally if the stability indicator (green) is lit with and without the sensing object. If it is not lit, stable operation cannot be expected, in which case a different sensing method must be applied. Unlike conventional photoelectric sensors, the variation in the sensitivity of E3S photoelectric sensors is minimal. This means the sensitivity can be adjusted on only a single photoelectric sensor, and then the adjustors on the other photoelectric sensors can be set to the same scale position. There is no need to adjust the sensitivity of each photoelectric sensor individually. 11 E3S-C E3S-C Dimensions Note: All units are in millimeters unless otherwise indicated.

Either separate the wiring, or use shielded lines as input/output lines to the photoelectric sensor. The cord connected to the E3S-C can be extended up to 100 m provided that the diameter of each wire of the cord is 0.3 mm2 minimum. If a standard switching regulator is used as a power supply, the frame ground (FG) terminal and the ground (G) terminal must be grounded, or otherwise the E3S-C may malfunction, due to the switching noise of the power supply. Startup Operation A maximum of 100 ms is required from the time power is turned on until the E3S-C is able to detect objects. If power is supplied to the loads and the E3S-C from different sources, turn on power to the E3S-C first. 20 Water Resistivity Do not use the E3S-C in water, in the rain, or outdoors. To ensure the water resistivity of the E3S-C, tighten the screws of the operation panel cover to a torque of 3.5 to 5.5 kgf S cm (0.34 N S m to 0.54 N S m). E3S-C E3S-C Oil and Chemical Resistivity Do not use the E3S-C in oils or liquid chemicals. Although the E3S-C is oil-resistive, 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. JIS classification Oil Product name Kinematic viscosity (mm2/s (cst)) at 40C Lubricating oil --- Velocite No.3 2.02 Water insoluble machining g oil No. 5, type 2 Daphnecut 10 min. and less than 50 No. 11, type 2 Yushiron Oil No. 2 ac Less than 10 No. 1, type W1 Yushiroken EC50T-3 --- Water soluble machining g oil Note: PH --- 7 to 9.5 Yushiron Lubic HWC68 7 to 9.9 No. 2, type W1 Griton 1700D 7 to 9.2 No. 1, type W2 Yushiroken S50N 7 to 9.8 1. The E3S-C maintained a minimum insulation resistance of 100 M after the E3S-C was dipped in all the above oils at a temperature of 50C 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. 3. JIS: Japan Industrial Standards Cable The E3S-C uses an oil-resistive cord to ensure oil resistivity. Do not allow the cable to be repeatedly bent during application. Do not allow the cable to be bent to a radius of less than 25 mm. 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 12 kgf S m (1.18 N S m) maximum. 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 E3S-C 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. Two, 4.5 dia. through holes M4 hole M4 hole Two, M3 M4 hole M4 hole M3 Malfunctioning If an inverter motor or servomotor is used with the E3S-C, the frame ground (FG) terminal and the ground (G) terminal must be grounded, or otherwise the E3S-C may malfunction. 21 E3S-C E3S-C Optical Axis Adjustment Direct the mounting axis of the mounting bracket in the direction where sensing objects will be located. The optical axis of the E3S-C coincides with the mounting axis of the mounting bracket, which enables the user to adjust the optical axis of the E3S-C with ease. Optical Lock Holes By tightening the optical axis lock holes with screws, the mounting bracket will be in the direction of the optical axis of the E3S-C. Optical axis Four M4 optical axis lock holes Mounting axis Optical Axis of Through-bean 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. Lens in use. The slit must be on this side. Lens not in use. 22 E3S-C E3S-C Replacing the E3S with the E3S-C The following is the conversion table for changing from the E3S to the E3S-C.

Especially take these items into consideration when replacing E3S models with E3S-C models. 2. When connecting the E3S-C to a timer or counter with voltage input, be sure to connect a 4.7-k resistor between the output and power supply lines. When the E3S-C is turned ON, a pulse signal may be output from the sensor. 23 E3S-C E3S-C ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527. Cat. No. E229-E1-3 In the interest of product improvement, specifications are subject to change without notice.
