Wiring
○Wiring connections
●
Connections should be made with the power supply turned off.
●
Use a separate route for the product wiring and any power or high voltage wiring. Otherwise, malfunction
may result due to noise.
●
If a commercially available switching power supply is used, be sure to ground the frame ground (FG)
terminal. If the switching power supply is connected for use, switching noise will be superimposed and it
will not be able to meet the product specifications. In that case, insert a noise filter such as a line noise
filter/ferrite between the switching power supplies or change the switching power supply to the series
power supply.
○Attaching the connector to the lead wire
●
Sensor wire is stripped as shown in the right figure.
(Refer to the table below for correspondence between connector
and electrical wire gauge.)

●
Check that the above-mentioned preparation work has been performed correctly, and part A shown in the
figure is pushed by hand and makes temporary connection.
●
Part A centre is pushed straight in using a suitable tool, such as pliers.
●
Re-use cannot be performed once it connects the connector for sensor connection completely. When the
connection fails or a pin is miswired, please use a new connector for sensor connection.
●
When the sensor is not connected correctly, [LLL] will be displayed.
●
Cable wire colour is applicable when an SMC sensor with lead wire is used.
