Composition
The SA Series consists of a controller, detector connection cables, and detectors.
As the controller, two types of master controller and five types of slave controller are available, and up
to 15 slave units can be connected to one master unit.
Four types of sensor heads are available.
Caution
■When connecting a slave unit to a master unit, these must be of the same output type,
i.e., both NPN-type or both PNP-type. Different output types cannot be connected
together.

3. Connection and Installation
3-1 Installation of Controller
Installation on the 35-mm wide DIN
rail
Fit the hook on the spring side into the DIN rail,
and while pushing it forward, fit the hook on the
fixing side into the DIN rail.
To remove, lift and disengage the hook on the
fixing side whilst pushing in the (fixing side) hook
direction (toward the side on which the top of the
case curves).
Connecting controllers
1) Attach the master unit onto the DIN rail.
2) Remove the connector cover.
3) Attach each slave unit onto the DIN rail
individually.
Remove the connector cover of the slave
unit, except for the unit at the end.
4) Connect the female connector to the male
connector by sliding the slave unit.
Caution
■Be sure to turn off the power before connecting slave units to or removing them from the
master unit. Connecting them with the power on may cause damage to the controller.
■When connecting a male connector into a female connector, press it in firmly as far as it
will go.
Imperfect connection may cause damage to the controller.
■If connecting two or more units, be sure to attach them onto the DIN rail.
When doing so, attach commercially available end plates at both ends so as to sandwich
the units between them.
■Up to 15 slave units can be connected to one master unit.
■When connecting a slave unit to a master unit, these must be of the same output type,
i.e., both NPN-type or both PNP-type. Different output types cannot be connected
together.
End plate
When attaching multiple connected units onto the DIN rail, or when units are not held stable on the DIN
rail, be sure to use commercially available end plates.

3-2 Connecting to Detector
Caution
■Keep the power OFF during wiring work.
Be sure to keep the power OFF when inserting a cable into or removing it from a
detector. Performing these operations with the power ON may result in electric shock or
failure.
Insert the controller connector of the detector cable into the detector cable connector of the controller.
After checking the orientation of the connector, push it in firmly as far as it will go.
To remove, press the lock release lever on the detector cable controller connector, hold the body of the
controller, and—whilst keeping the lever pressed—pull out the connector.
Please note that, when removing the connector, pulling the cable without pressing the lock release
lever may result in the cable breaking off or the connector being damaged.

3-3 Changing the Length of the Detector Cable
Move the protecting cover in the direction of the arrow.
With a flat-blade screwdriver (tip width of 2 mm or less), push in the control lever (white) located at the
wire insertion port, and remove the wire.
Using the STRIP GAUGE shown on the side of the body, strip the cable sheath so as to expose 7 to
8 mm of core wire, and twist the core wires several times.
Using a flat-blade screwdriver of tip width of 2 mm or less, push in the control lever (white) of the control
section until it locks.

Insert the wire into the wire insertion port as far as it will go. As in the figure below, check that the
sheathed section of the wire reaches inside the wire insertion port, and that the tip of the core wires
passes through the connection section.
Caution
■Be careful to ensure that wiring is performed correctly, as wiring errors may result in failure.
Through the release port, apply the tip of a flat-blade screwdriver to the lower part of the control lever
(white), and move the tip of the screwdriver upwards. A snapping noise indicates that the control lever
(white) has returned to its original position, thereby fixing the wire.
Pull lightly on the wires to check that they are not loose.
Move the protecting cover in the direction of the arrow to return its original position.
