Wiring Guide
Power supply terminal Connect a power supply with a capacity of 150 mA minimum at 12 to 24 VDC.
0 V Used as the common terminal for the enable output and laser OFF input.
Enable output Turned on with open collector output when the sensor can be operated (the stability indicator
is not red).
Laser OFF input The laser emission of the sensor will be turned off by short-circuiting the laser OFF input line with
the 0-V terminal (with a residual voltage of 2 V max.), and the linear output of the sensor will be
ON HOLD at this time.
Linear output According to the displacement value, the following output will be obtained.
Z4M-W40RA/-W100RA: current output, 4 to 20 mA
Linear GND Used as a ground (0V) terminal for the linear output of the sensor. Connect this line to the input device.
Note: 1. If high resolution is required, connect an independent regulated power supply to the sensor. Place in increasing accuracy or
resolution.
2. Wire the sensor correctly (refer to the Precautions Section), or the sensor may be damaged. The linear output line must not be
in contact with any other line.
3. The 0-V (blue) and linear GND (shielded) line are internally connected via a resistor. Use the 0-V (blue) line for the power
supply and use the shield wire (linear GND) and linear output (black) line for linear output.
J MUTUAL INTERFERENCE
When using more than two sensors in close proximity to each other, separate each sensor as specified in this table.

Z4M-W100RA 60 mm (2.36 in)
J POWER SUPPLY
Use an insulated transformer for the power supply of the Z4M,
as shown in the illustration provided below.
Do not use an autotransformer. Use of an autotransformer
may cause the Z4M to malfunction.

J WIRING
DANGER!
Do not wire the power supply cable for the Z4M
Sensor in the same conduit with high-voltage lines
or power lines. The result would be interference,
damage, or malfunction.
Extension Cable
A Z49-C1 Extension Cable can be connected to the
Sensor cable or to the amplifier cable. The total
length of the Sensor cables or amplifier cables
must not exceed 10 m (32.91 ft.). To extend the
amplifier cable, use a shielded cable of the same
kind.
