E2K-X
When mounting the proximity sensor in or near a metallic panel, be sure to provide a minimum distance as shown in the tables below. This
prevents the sensor from being affected by metallic objects other than the target.
When Mounting Directly to Metal Panel or Object
When Using Optional Mounting Brackets
To prevent mutual interference between two sensors, be sure to space the two sensors at a distance greater than that shown in the table
below.
DC Switching Sensors
In applying any of the E2K-X ME series proximity sensors as a
voltage output type, note that an unwanted output may be pro-
duced momentarily (50 ms max.) when power is applied with a
target moving toward the E2K-X ME1(F1) or with a target
moving away from the E2K-X ME2(F2). After the power appli-
cation, a minimum of 50 ms is required before the sensor circuit
can operate. Move the target toward or away from the proximity
sensor after this time period.
If a high voltage or power line runs near the proximity sensor
cable, be sure to wire the sensor cable through a metal conduit to
protect the sensor from malfunctioning or damage.
The proximity sensor is provided with a surge suppressor circuit.
However, if any large surge generation source (i.e. motor, weld-
ing machine, etc.) exists in the vicinity of the proximity sensor,
insert a surge suppressor (such as a varistor) into the surge
generating source.

AC Switching Sensors
After applying power to a proximity sensor, a minimum of 100 ms
is required before the sensor circuit reaches its steady state. The
load is in the OFF state during this period. Do not move the target
toward or away from the proximity sensor until the sensor circuit
enters the steady state. The operation indicator (LED) will
illuminate momentarily when the power is turned ON or OFF, but
the output stage circuit is in a normal operating state.
