*1. Beam size: The beam size is defined by 1/e2 (13.5%) of the strength of the beam at the beam center (measured value). Incorrect detection may
occur if there is light leakage outside the defined spot and the material around the sensing object is more reflective than the sensing object.
*2. Resolution: The resolution is the deviation (±3σ) in the linear output when connected to the ZX-LDA Amplifier Unit. (The resolution is measured
with the standard reference object (white ceramic), at the measurement point with the ZX-LDA set for an average count of 4,096 per period.)
The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the distance accuracy. The resolution may
be adversely affected under strong electromagnetic fields.
*3. Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring the standard reference object. The
linearity and measurement values vary with the object being measured.
*4. Temperature characteristic: The temperature characteristic is measured at the measurement point with the Sensor and reference object
(OMRON’s standard reference object) secured with an aluminum jig.
Note: Highly reflective objects can result in incorrect detection by causing out-of-range measurements.

into the measurement width.

Note 1. Use a separate stabilized power supply for the Amplifier Unit,
particularly when high resolution is required.
2. Wire the Unit correctly. Incorrect wiring may result in damage to
the Unit. (Do not allow wiring, particularly the linear output, to
come into contact with other lines.)
3. Use the 0-V line (blue) for the power supply and use the shield
wire (linear output ground) together with the linear output (black
line) for linear output. Each of these grounds must be used for
the designed purpose. When not using the linear output, con-
nect the linear ground (shield) to the 0-V ground.

objects that are smaller than the Sensor’s spot diameter or have ex- • Locations subject to rapid changes in temperature.
treme curvature or inclination. • Locations subject to freezing.

Power Supply and Wiring

• Prior to turning ON the power supply after wiring is completed,
check to make sure that the power supply is correct, that there are
no mistaken connections, e.g., connections that would short-circuit
the load, and that the load current is appropriate. Incorrect wiring
may result in damage to the Sensor or Unit.
• The total length of the Sensor cable or Amplifier cable must be 10 m
or less. Use an ZX-XC@A Extension Cable (order separately) if re-
quired to extend the cable from the Sensor. Use a shielded cable to
extend the Amplifier cable. The shielded cable must be the same as
that of the Amplifier cable.
• Do not lay a power supply cable for the ZX together with high-volt-
age lines or power lines to prevent interference, damage, and mal-
function.
• 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 ab-
sorber that meets the conditions of the usage environment.
• When using a Calculating Unit, connect the corresponding linear
ground of the Amplifier Unit.

Compatibility
• All Sensor Heads and Amplifier Units are compatible. Different Sen-
sor Heads may be purchased at a later date and used with existing
Amplifier Units.

Mutual Interference
• Two Sensor Heads can be used together, without danger of mutual
interference, by connecting the ZX-CAL 2 Calculating Unit between
two Amplifier Units.

Maintenance
• Always turn OFF the power supply before adjusting or removing the
Sensor Head.
• Cleaning
Do not use thinners, benzine, acetone, or kerosene for cleaning.
If dust or oil adheres to the filter on the front of the Sensor Head,
use the following procedure to clean.
1. Use a blower brush (used to clean camera lenses) to blow
large dust particles from the surface. Do not blow the dust
away with your mouth.
2. Use a soft cloth (for lenses) with a small amount of alcohol to
remove the remaining dust. Do not use a scrubbing action
when cleaning because scratches on the filter could result in
Sensor inaccuracy.

Laser Safety
The ZX-LD-Series Sensor Heads are FDA Class II and EN Class 2 Laser Products. The ZX-LT-Series Sensor Heads are FDA Class II and EN
Class 1 Laser Products. The ZX Series is meant to be built into final system equipment. Pay special attention to the following precautions for the
safe use of the product:
Note: Europe: Class 1 and Class 2 of EN60825-1: 1994 = IEC825-1: 1993
U.S.A.: Class I and Class II of FDA (21 CFR1040.10)
1. Use this product as specified in this instruction manual. Otherwise, you may be exposed to hazardous laser radiation.
2. The ZX-series Smart Sensors radiate laser beams in the visible light range. Do not expose your eyes directly to the laser radiation. Ensure
that the laser beam path is terminated during use. If a mirror or shiny surface is positioned in the laser beam path, ensure that the reflected
beam path is also terminated. If the Unit must be used without terminating the laser beam path, position the laser beam path so that it is not
at eye level.
3. To avoid exposure to hazardous laser radiation, do not displace nor remove the protective housing during operation, maintenance, and any
other servicing.
4. The user should return the product to OMRON for all repair and servicing.
5. As for other countries, observe the regulations and standards specified by each country.

Class Description
Class 1 Lasers which are safe under reasonably foreseeable conditions of operation.
Class 2 Lasers emitting visible radiation in the wavelength range from 400 nm to 700 nm. Eye protection is normally afforded by
aversion responses including the blink reflex.
Class 3A Lasers which are safe for viewing with the unaided eye. For laser emitting in the wavelength range from 400 nm to 700 nm,
protection is afforded by aversion responses including the blink reflex. For other wavelengths the hazard to the unaided
eye is no greater than for Class 1. Direct intrabeam viewing of Class 3A lasers with optical aides (e.g., binoculars, tele-
scopes, microscopes) may be hazardous.
Class 3B Direct intrabeam viewing of these lasers is always hazardous. Viewing diffuse reflections is normally safe (see note).
Class 4 Lasers which are also capable of producing hazardous diffuse reflections. They may cause skin injuries and could also
constitute a fire hazard. Their use requires extreme caution.

Note: Conditions for safe viewing of diffuse reflections for Class 3B visible lasers are: minimum viewing distance of 13 cm between screen and
cornea and a maximum viewing time of 10 s. Other viewing conditions require a comparison of the diffuse reflection exposure with the MPE.
