Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Precautions for Correct Use
Make sure that this product is used within the rated ambient
environment conditions.
● Wiring
Connections
The length of the standard cable is 10 m max. (including the cable
attachment, AWG24 min.). When extending the Sensor wires, use a
wire greater than AWG 22 in diameter and a cable shorter than
100 m. If the cable length exceeds 10 m, the supply voltage applied
at the Sensor terminal will decrease as the impedance of the
extended cable increases and the low level output voltage at the cable
end will increase. Therefore, take voltage fluctuation into account
when extending the Sensor cable.
● Mounting
Tighten the mounting screws to a torque of 0.54 N·m max.
EE-SPW321/421
● Adjustment
Aperture Stickers
Two kinds of reticles are attached, the 0.5-mm and the 1.0-mm width
types (total of 4 stickers with slit widths A to D as shown in the
following diagram).
Use these when the sensing object is 2 mm or smaller or when mutual
interference must be reduced.
For each slit of the same type, attach a sticker to the sensing surface
of the emitter and receiver.

Note: These are pressure sensitive
adhesive-type stickers.
Peel off the seal and stick it on the
lens.
Optical Axis Adjustment
(1)Set the Sensor so that the center of the lens in the emitter and
receiver form one line.
(2)Having checked that the Sensor is correctly wired, turn ON the
power. The operation indicator on the amplifier of the emitter will
light. Check to make sure the light goes ON and OFF when an
opaque object is moved in and out between the emitter and
receiver.
(3)Move the emitter (or receiver) up and down, left and right and
secure the emitter (or receiver) in the center of the range of the
operation indicator. Secure the receiver (or emitter) in the same
way after adjustment is complete.
