Precautions for Safe Use
Precautions for Safe Use
The following points are important to ensure safety, so make sure that they are strictly observed.
■ Installation Environment
• Do not use the product in environments where it can be exposed to inflammable/
explosive gas.
• Do not install the product close to high-voltage devices and power devices in order to
secure the safety of operation and maintenance.
■ Power Supply and Wiring
• The supply voltage must be within the rated range.
• Open-collector outputs should not be short-circuited.
• High-voltage lines and power lines must be wired separately from this product. Wiring
them together or placing them in the same duct may cause induction, resulting in
malfunction or damage.
• Avoid connecting or disconnecting connectors while the product is powered ON.
Doing so may damage the product.
• Reverse connection of the power supply and output terminals is not allowed.
Connection to an AC power supply is also not allowed.
• Connect a supply voltage and current within the rated ranges to the output terminals.
Introduction
■ Others
• Do not disassemble, repair, or modify this product.
• This product is not compatible with the ZX series. Do not connect a ZJ-S___ in
combination with a ZX series Amplifier Unit.
• Supply power from a UL Class 2 DC power supply or a DC power supply unit that has
a countermeasure (safety ultra-low voltage circuit) built-in for preventing high voltages
from occurring.
• Be sure to insulate the sensor case as it is connected to the 0 V line of the internal
circuits.
• Always ground the 0 V terminal to prevent electrical shock and to enable performing
measurements correctly.
• Do not operate this product with wet hands. Doing so might cause a malfunction.
• Do not ground the 24 V terminal. Doing so may cause malfunctions.
• Do not drop this product or subject it to strong shock. Doing so might cause a
malfunction.
• Prevent static discharge from being applied to the Sensor Head even if it is operating
within the measurement voltage range. Doing so might cause a malfunction.
• Dispose of this product as industrial waste.

Precautions for Correct Use
Precautions for Correct Use
Observe the following precautions to prevent failure to operate, malfunctions, or undesirable effects on
product performance.
■ Installation Site
Do not install the product in locations subjected to the following conditions:
• Ambient temperature outside the rating
• Rapid temperature fluctuations (causing condensation)
• Relative humidity outside the rating
• Presence of corrosive or flammable gases
• Presence of dust, salt, or iron particles
• Direct vibration or shock
• Direct sunlight
• Water, oil, or chemical fumes or spray
• Strong magnetic or electric field
Component Installation and Handling
■ Power Supply and Wiring
• The cables must be 10 m or shorter in total length, for both the sensor and Amplifier
Unit. To extend the cable from the Sensor Head, an optional double-ended connector
cable (ZX-XC_A) must be used. For extension of the cable of Amplifier Units, shielded
cables of the same type must be used.
• When using a commercially available switching regulator, make sure that the FG
(Frame Ground) terminal is grounded.
• If surge currents are present in the power lines, connect surge absorbers that suit the
operating environment.
• When two or more Amplifier Units are connected by a Calculating unit (ZX-CAL2) for
use, connect the linear GND of all Amplifier Units.
■ Warming Up
After turning ON the power supply, allow the product to stand for at least 30 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measured values may fluctuate gradually.
■ Maintenance and Inspection
• Always turn OFF the power supply before adjusting or connecting/disconnecting the
Sensor Head.
• Do not use thinner, benzene, acetone or kerosene to clean the Sensor Head and
Amplifier Units.
• Do not allow dust to enter the measurement section.

Section 1 FEATURES
The ZJ-SD is a series of static electricity sensors. The purpose of these sensors is to measure
the electric potential of the surface of a workpiece charged with static electricity.
Example: Measurement of the potential of a PCB
Measured value outputs
Judgment outputs
2
■ High-precision Detection by Distance Correction
The sensor that measures the charged amount of the workpiece is greatly dependent
on the distance up to the workpiece.
The ZJ-SD series can be connected to a ZX displacement sensor so that distance
correction can be performed on the charged amount using that measurement data and
non-uniform workpieces can be measured to high precision.
Also, if the installation distance up to the workpiece is fixed beforehand, distance
correction can be performed and highly accurate measurement ensured by directly
inputting the distance to the ZJ-SD.
