Mounting Unit
■ Mounting on a DIN Rail
1 Align the claw at the bottom of the main body with
the DIN rail. While pushing the main body in the
direction of the arrow 1, slant it in the direction of
the arrow 2.
2 To dismount the sensor, raise the main body in
the direction of the arrow 3 while pushing the
main body in the direction of the arrow 1.
■ Installation on a Wall (Main Unit Only)
Attach the unit to the optional mounting bracket
(OP-73880), mount them together, and secure
them with two M3 screws as shown in the illus-
tration.
Connecting Multiple Amplifiers
Up to 16 sub units can be connected to one main unit.
1 Remove the protection cover on the side of
the main unit.
2 Install the amplifier one by one on the DIN rail.
3 Engage the two claws of the child unit with the
recesses on the main unit side until you hear a
click sound.
4 Attach the end units (option: OP-26751) to the
both ends of the connected amplifiers in the
same way as in step (2).
5 Sandwich the amplifiers between the end
units. Tighten the screws at the top (two
screws x two units) with a Phillips screwdriver
to fix the end units.
Connecting Fiber Unit
1 Open the dust cover in the direction
shown by arrow 1.
2 Move down the fiber lock lever in the
direction shown by arrow 2.
3 Insert a fiber unit into the fiber insertion
holes to a length of the fiber insertion sign
(i.e., approximately 14 mm).
4 Move down the fiber lock lever in the
direction shown by arrow 4.
Note
If a thin fiber unit is used, an adapter provided with the thin fiber unit will be required.
Unless the right adapter is connected, the thin fiber unit will not detect targets correctly. (The
adapter is supplied with the fiber unit.)
• To connect the coaxial reflective type fiber unit to the amplifier, connect the single-core fiber
to the transmitter side, and connect the multiple-core fiber to the receiver side.
Warning
• This product is used to detect targets. Do not apply the product to
safety circuits for human protection.
• This product is not of explosion-proof construction. Do not use the
products in places with flammable gas, liquid, or dust.
•
This product is a sensor of DC power supply type. Do not apply AC
power. The product may explode or burn if an AC voltage is applied.
