Built-in Amplifier Photoelectric Sensor
Revolutionary High-performance High-quality Sensor with Built-in Amp
Optical axis can be adjusted in seconds because the optical axis coincides with the mounting axis. Highly visible spot on white paper (except 10-cm and 70-cm Diffuse Reflective Sensors). Two-turn sensitivity adjustment with consistent scale reading to enable setting multiple sensors without adjusting each individually (for Diffuse Reflective Sensors). Stable detection at a distance of from 0.2 to 70 cm (E3S-ADj2, E3S-ADj7). Washable in water (IP67, NEMA 4X enclosure rating). A total of 72 different modes to match essentially every need. Built-in mutual interference prevention function. E39-E6/E8 Filters for mutual interference prevention available.

1. The items marked with an asterisk are particularly important when replacing the E3S with the E3S-A. 2. When connecting the E3S-A to a timer or counter with voltage input terminals, be sure to connect a resistor between the output and positive power supply terminals (e.g., 4.7-k# resistor that withstands 1/4 W for a supply voltage of 12 VDC and 10-k# resistor that withstands 1/4 W for a supply voltage of 24 VDC), in which case the sensor may output a pulse signal the moment power is supplied to the E3S-A.

The sensor is normal if the control output varies when the self-diagnostic external input is ON and OFF. The sensor is abnormal if the control output does not vary when the self-diagnostic external input is turned ON or OFF. Note: Before using the self-diagnostic external input function, the incident light beam to the sensor must not be blocked by an object.

Timer and Turbo Switch (Sensors with Self-diagnostic Output Function)
The E3S-A Sensor equipped with the self-diagnostic feature incorporates an OFF-delay timer that can be adjusted within a range of 0 to 100 ms. The emitter of the through-beam sensor with the self-diagnostic feature incorporates a turbo switch. When this switch is on, the intensity of the red LED light source can be increased to make a brighter spot. The OFF-delay time adjustor of the retroreflective and the 20-cm diffuse reflective sensor is used as a turbo switch. When the adjustor is pressed, it functions as a turbo switch to automatically increase the power of the light source to create a brighter light spot. Do not press the adjustor when turning it.

Procedure
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.
Remove the sensing object and gradually decrease sensitivity by turning the sensitivity adjustor counterclockwise from the maximum scale position until the incident light indicator (red LED) is OFF. Position B is where the indicator has turned off. Regard the minimum scale position as Position B if the indicator does not turned ON at minimum sensitivity.
Set the sensitivity indicator to the position between Positions A and B (in some cases, Positions A and B 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 detection 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.
19
E3S-A/B Turbo Function (Turbo Switch)
With the turbo function switched ON, the light spot is visible even at a distance of 20 cm, making it easy to check the sensing position and the angle of the optical axis. 1. After using the turbo function, readjust the OFF-delay time that had been set, since the OFF-delay time could have been changed when the turbo switch (which is on the OFF-delay time adjustor) was pressed. With Turbo Switch ON The turbo function is effective with the turbo switch pressed, and the function is reset automatically when released.
E3S-A/B
2. Press the OFF-delay time adjustor to switch ON the turbo function with a maximum force of 1 kg and within a maximum period of 3 min. (The photoelectric sensor, however, will not malfunction even if the turbo function is switched on for more than 3 min.)

Precautions
E3S-A/B
The supplied voltage must be within the rated voltage range. Unregulated full-or half-wave rectifiers must not be used as power supplies. If the input/output lines of the photoelectric sensor are placed in the same conduit or duct as power lines or high-voltage lines, the photoelectric sensor could be induced to malfunction, or even be damaged, by electrical noise. Either separate the wiring, or use shielded lines as input/output lines to the photoelectric sensor. Do not use a hammer to hit the amplifier when mounting or the amplifier will loose watertightness. Note the following when using the E39-R3, E39-RSA, or E39-RSB reflector (tape): 1. Before applying adhesive tape to the reflector, make sure that the reflector is free from oil or dust, or otherwise the adhesive tape will not stick to the reflector properly. 2. Do not cut the reflector or the reflector will loose watertightness. 3. Do not press the reflector with a metal object or a nail, or otherwise the reflector will not function properly.
Position of Optical Axis of Through-beam Model
Unlike conventional through-beam models, the E3S Through-beam Photoelectric Sensor incorporates 2 lenses. But the lens actually in use is the one marked with an arrow indicating the position of the optical axis. When using a slit, attach it to the lens marked with the arrow.

Mounting Bracket
The direction of the optical axis coincides with the mounting direction of the E3S when the mounting screw is inserted into the lock hole of the mounting bracket. Unlike conventional photoelectric sensors, if the sensing object (or the retroreflector in the case of a through-beam sensor) is in the mounting direction of the photoelectric sensor, the object is detected with the incident light without the time-consuming adjustment of the optical axis (but if the mounting surface is not flat, the adjustment of the optical axis may still be required).

Adjustor Cap
In order to prevent the sensitivity or OFF-delay time that has been set from changing accidentally enclosed, cover the adjustors with the adjustor cap (enclosed).

Mutual Interference Filter (E39-E6/-E8)
A set of 4 filters are sold together for two through-beam models (for 2 each of emitters and receivers). For mounting, refer to the figure of the slit for the E3S-A Photoelectric Sensor.
Emitter
The maximum tightening torque applied to the screw is 5.5 kgf S cm (0.53 N S m). E3S-B
Align the upper side of the photoelectric sensor with that of the mounting bracket so that the photoelectric sensor will be parallel to the base of the mounting bracket.
Insert this protruding portion to the optical axis lock hole.

Receiver
Be aware of the direction of polarization.

The arrow printed on the cover indicates the direction of polarization. By attaching the filters opposite to each other in polarization to the emitters and the receivers (refer to the figure) in rows, mutual interference can be prevented (in any case, the filter attached to an emitter and to the corresponding receiver must be the same in direction of polarization or the photoelectric sensor will not function).
Align the rear side of the photoelectric sensor with that of the mounting bracket so that the photoelectric sensor will be vertical to the base of the mounting bracket.
Note:
The maximum tightening torque applied to the screw is 5.5 kgf S cm (0.53 N S m).

To permanently use the knob to adjust the sensitivity of the photoelectric sensor, insert side B into the shaft (the knob cannot be removed if once side B is inserted into the shaft). Slit (E39-S46 Order Separately) for E3S-A Use the rubber attachment with the metal cover if a slit width of 2 mm is required. Insert the 0.5- or 1-mm slit between the metal cover and rubber attachment if a slit width of 0.5 or 1 mm is desired. These slits fit into the rubber attachment.

Attach the reflector to the receiver (refer to the figure). Look at the reflector from right behind the emitter. The reflector should be bright with red light when the optical beam strikes the reflector. If the emitter has a turbo function, the reflector looks brighter with the function switched on. When the reflector is removed, the light beam strikes the receiver.

Installation of Accessories
Slit (E39-S47, -S48 Attachment) Peel off the protective sheet and attach the slit seal to the emitter panel of the photoelectric sensor. Do not touch the panel or the lens by hand in order to avoid oil sticking on the panel surface. Remove any oil on the panel or the slit will not stick properly. Note: Like the E3S-A Photoelectric Sensor, apply the slit to the lens of the E3S-B Photoelectric Sensor marked with an arrow indicating the position of the optical axis (apply it to the bottom side lens of both the horizontal and the vertical models).
