E3X
Bending Radius
E39-F11 Sleeve Bender
The bending radius of the stainless tube should be as large as pos-
sible. The smaller the bending radius becomes, the shorter the
sensing distance will be.
Insert the tip of the stainless sleeve to the Sleeve Bender and bend
the stainless sleeve slowly along the curve of the Sleeve Bender (re-
fer to the figure).

Handling
E32-D51/-T51 Heat-resisting Fiber
The bending radius of the fibers should be 35 mm min.
Connecting fibers via the E39-F10 Fiber Connector is not possible.
The withstand temperature of the Heat-Resisting Fibers is 150°C
max. In continuous operation, the ambient temperature should be
130°C max.
E32-T14/-T51
If the sensor is ON because some object in front of the lenses re-
flects light, attach the black seals (sold together) to the lenses.

Seal
E32-L25 (A) Wafer Sensor
Insert the fiber with a white line into the light projection side of the
Amplifier.
The tightening force of the sensor head is 8 kgf S cm (0.75 N S m).
Avoid places where water could be sprayed onto the E32-L25(A).
E32-T16 Slit Seal (Attachment)
Peel the E32-T16 Slit Seal off the ground paper and affix the Slit
Seal to the sensing face of the sensor so that the corners of the Slit
Seal fit in with the corners of the sensing face. To sense an object at
a distance of 30 cm max., a 0.5-mm wide Slit Seal must be used.

Mounting
Mounting
1. Mount the front part on the mounting bracket (sold together)
or a DIN rail.
2. Press the back part onto the mounting bracket or the DIN rail.

Dismounting
By pulling back the lock (yellow) on the bottom with a flat blade
screwdriver, the Amplifier can be dismounted with ease.
In the case of side mounting, attach the mounting bracket on the
Amplifier first, and secure the Amplifier with M3 screws and wash-
ers. The diameter of the washers should be 6 mm max.

When power is off:
The moment power is turned off, the E3X could output a pulse signal
which could affect the operation of the devices connected to it. This
will happen more often if power is supplied to the E3X from an exter-
nal power supply, thus affecting the connected timer and counter.
Use a built-in power supply as much as possible to avoid this.
If power is supplied to a photoelectric sensor through a cord that is
wired together with other power lines in the same duct, the cord will
be influenced by the power lines and malfunctioning of the photo-
electric sensor or damage could result. Wire the cord separately or
use a sealed cord to supply power to the photoelectric sensor.
In the case of the cord is extended, use a wire with 0.3 mm² max..
The total length of the cord should be 100 m max.

Power supply:
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 E3X can malfunction, influenced by the
switching noise of the power supply.
The supplied voltage must be within the rated voltage range. Unreg-
ulated full- or half-wave rectifiers must not be used as power sup-
plies.
Do not use a hammer to hit the Amplifier when mounting or the Am-
plifier will loose watertightness.
