Note 1. The resolution is given as the minimum value that can be read when a ZX-TDA@1 Amplifier Unit is connected. This value is taken 15 min-

utes after turning ON the power with the average number of operations set to 256.

2. The linearity is given as the error in an ideal straight line displacement output.

3. These figures are representative values that apply for the measurement mid-point, and are for when the provided actuator is used, with

the actuator moving downwards. If the actuator moves horizontally or upwards, the operating force will be reduced. Also, if an actuator
other than the standard one is used, the operating force will vary with the weight of the actuator itself.

4. These figures are representative values that apply for the mid-point of the measurement range.

Note 1. Use a stabilized power supply separate from other devices

and power systems for the Amplifier Unit, particularly when
high resolution is required.

2. Always wire correctly. Incorrect wiring may damage the Unit.

Use a different ground for the linear output from the normal
ground.

3. The blue line (0 V) is the 0 V power supply line. The shield

wire (linear output GND) is used together with the black line
(linear output) to connect the linear output. Wire these lines
correctly. Always ground the linear output terminal even when
the linear output is not used.

Replacing Actuators

Be careful not to damage the rubber boot with pliers or other tools
when replacing the actuator.

1. Remove the standard actuator.

• Hold the plunger’s D-cut section with radio pliers or a similar tool

while removing the actuator.

• If the replacement must be performed by holding the Sensor Head

itself, ensure that a torque exceeding 0.15 N·m is not applied.
Applying excessive torque may have an adverse affect on plunger
operation.

Width: 1 mm

Rubber boot

2. Mount the commercial actuator to the Conversion Adapter.

• Tighten the actuator securely, and ensure that there is no loose-

ness.

• If necessary, apply a screw-locking agent.

a similar tool

(e.g., one with a flat end)

3. Mount the Conversion Adapter to the plunger.

• Hold the plunger’s D-cut section with radio pliers or a similar tool

while mounting and securing the Conversion Adapter.

• If the replacement must be performed by holding the Sensor Head

itself, ensure that a torque exceeding 0.15 N·m is not applied.
Applying excessive torque may have an adverse affect on plunger
operation.

Precautions

Design Precautions

• Conform to the specified ratings and performance. Refer to Specifi-

cations on page B-78 for details.

• Measurements may not be possible or may not be accurate for

some materials and shapes.

• The Sensor will be destroyed if the Actuator is pressed too far. Do

not use the Actuator past the point where a pressing force alarm
(OVER) is displayed.

• Do not remove the rubber boot. Without the rubber boot, foreign

matter may enter the Sensor Head, possibly causing the Sensor
Head to malfunction.

• Use suitable torque and force when mounting the Sensor. Refer to

page B-81 for details.

• The Sensor may be destroyed if excessive force is applied.

Environment

• Do not operate the product in locations subject to flammable or

explosive gases.

• In order to ensure safe operation and maintenance, do not install

the product in the vicinity of high-voltage devices or power equip­ment.

Wiring

• Do not use the product at voltages exceeding the rated values.

Doing so may result in damage.

• Do not connect the product to an AC power supply or connect the

power supply in reverse.

• Do not short-circuit the load for open-collector output.

Correct Use

• System Design

Warming Up

After turning ON the power, allow the Smart Sensor to warm up for
15 minutes minimum prior to use.

Measurements

Do not expose the plunger to forces exceeding the limits in the fol­lowing diagram. Doing so may damage the plunger.

30 N 30 N 1 N 0.15 N·m

• Adjustments

Settings

When setting the threshold value with the Smart Sensor connected
to an external device, turn ON the Amplifier Unit's judgement output
hold input to prevent the judgement from being output to the external
device.

• Compatibility

Sensors and Amplifier Units are mutually compatible. Sensors can
be added or replaced individually.

• Influence of High-frequency Electromagnetic Fields

Using the product in the vicinity of devices that generate high-fre­quency electromagnetic fields, such as ultrasonic cleaning equip­ment, high-frequency generators, transceivers, mobile phones, and
inverters, may result in malfunction.

Other Precautions

Do not attempt to disassemble, repair, or modify the product.
Dispose of the product using standard procedures for industrial

waste.
These Sensors are not compatible with the ZX-L@@ Smart Sensors

(laser type). Do not connect combinations of ZX-E@@ Smart Sen­sors and ZX-T@@ Smart Sensors.

B-82 Displacement sensors / Width-measuring Sensors

Wiring

• Wiring Check

After wiring is completed, before turning ON the power, confirm that
the power supply is connected correctly, that there are no faulty con­nections, such as load short-circuits, and that the load current is cor­rect. Incorrect wiring may result in failure.

• Cable Extension

Do not extend the cable for the Sensor and the Amplifier Unit to a
length exceeding 10 m. Use a ZX-XC@A Extension Cable (sold sep­arately) to extend the Sensor’s cable. Extend the Amplifier Unit’s
cable using a shielded cable of the same type.

• Power Supply

When using a commercially available switching regulator, ground the
FG (frame ground) terminal.

If the power supply line is subject to surges, connect a surge
absorber that meets the conditions of the operating environment.
