All voltage photoelectric sensors
E3JK
• Built-in amplifier accepts wide supply
voltage range.
• Slim, space-saving construction mea-
sures only 50 x 50 x 17.4 mm.
• Relay outputs with long life expectan-
cy and high switching capacity (3 A,
250 V AC).
• Polarized retroreflective type available
for glossy or shiny object detection.
* The value within the parentheses indicates the sensing distance applied when the E39-R2 reflector is used.
Note: The UL-listed model ends with "-US". (Example: E3JK-5M1-US). Note that the DC transistor type of the E3JK is UL-unlisted.

* Values in parentheses indicate the minimum required distance between the sensor and reflector.
Note: When the reflector used is other than the supplied one, set the sensing distance to about 0.7 times of the typical example as a guideline.

Precautions
Design
Power Reset Time
The Sensor is ready to detect an object within 200 ms after it
is turned ON. If Sensor and load are connected to separate
power supplies, ensure to turn ON the Sensor first.
Wiring Considerations
Connection/Wiring
If the DC transistor output type is used, the sum of load cur-
rents of L-ON output (NO) and D-ON output (NC) should be
within 100 mA. If the sum of load currents exceeds 100 mA,
the load short-circuit protection may be activated. (The load
short-circuit protection is reset by turning OFF the power of
the photoelectric sensor.)
Miscellaneous
Ambient Conditions (Installation Area)
The E3JK will malfunction if installed in the following places.
• Places where the E3JK is exposed to a dusty environment.
• Places where corrosive gases are produced.
• Places where the E3JK is directly exposed to water, oil, or
chemicals.

E3JK
Swing the receiver and emitter ver-
tically and/or horizontally and set
the adjuster in the center of the
range where the indicator of the re-
ceiver turns ON.
Like the through-beam model, ad-
just the reflector and emitter/re-
ceiver. Since the directional angle
of the emitter/receiver is 1 to 5°, ad-
just the emitter/receiver especially
carefully.
(1) If you have a sensing object as shown in the figure, turn the sensitivity
adjuster clockwise (increase the sensitivity) until the indicator is turned
ON, and define this adjuster position as (A).
(2) Remove the sensing object, turn the sensitivity adjuster clockwise until
the indicator is turned ON by a background object, and define this posi-
tion as (B).
(3) Turn the sensitivity adjuster counterclockwise (decrease the sensitivity)
from (B) until the indicator is turned OFF, and define this position as (C).
(4) The position in the middle of (A) and (C) is the optimum position. If the
indicator is not turned ON by the background object at the maximum
sensitivity, set the adjuster in the middle of (A) and maximum sensitivity.
The sensitivity adjuster may be damaged if an excessive force is applied.
