Replacing Actuators - Omron ZX-T Datasheet

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.

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.

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 equip-
ment.
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.

Conversion Adapter
(D5SN-TA)
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.

a similar tool
Measurements
Do not expose the plunger to forces exceeding the limits in the fol-
lowing diagram. Doing so may damage the plunger.
ZX-TDS-Series Sensors
• 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-fre-
quency electromagnetic fields, such as ultrasonic cleaning equip-
ment, 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 Sen-
sors and ZX-T@@ Smart Sensors.
