All voltage photoelectric sensors
E3JK
E3JK
• Built-in amplifier accepts wide supply
voltage range.
• Slim, space-saving construction measures only 50 x 50 x 17.4 mm.
• Relay outputs with long life expectancy and high switching capacity (3 A,
250 V AC).
• Polarized retroreflective type available
for glossy or shiny object detection.

(2) Remove the sensing object, turn the sensitivity adjuster clockwise until
the indicator is turned ON by a background object, and define this position 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.

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 currents 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
