In Europe, diffuse-reflective models in the ZX2 Series are categorized as Class 2 laser
products and the regular-reflective model is classified as a Class 1 laser product
according to EN60825-1 (see note).
The CE markings on the products also reflect these categorizations.
In the U.S.A., diffuse-reflective models in the ZX2 Series are categorized as Class II laser
products, and the regular-reflective model is classified as a Class I laser product
according to IEC60825-1 criteria, in accordance with the stipulations of the FDA standard
Laser Notice No. 50 (see note).
This product has already been registered with the CDRH (Center for Devices and
Radiological Health). (Accession Number: 1020665)
Place the laser warning label and the FDA label on the sensor.
The ZX2 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 EN 60825-1: 1994 +A11:1996 +A2:2001
= IEC 60825-1:1993 +A1:1997 +A2:2001
U.S.A.: Class I and Class II of FDA (21 CFR1040.10)
(1) ZX2-LD emits visual laser beam. Do not stare directly into the laser.
Make sure that the laser beam path is terminated. If specular objects are present in
the laser beam path, make sure that they are prevented from reflecting the laser
beam.
When used without an enclosure, make sure the laser path from eye level is avoided.
(2) To avoid exposure to hazardous laser radiation, do not displace nor remove the
protective housing during operation, maintenance, and any other servicing.
(3) As for countries other than those of Europe and the U.S.A., observe the regulations
and standards specified by each country.
(4) Label Indications
The EN and FDA labels are supplied with the product.
Replace the current labels with them according to the instructions given in the
manuals.

connectors.
Applicable standards
• EN61326-1
• Electromagnetic environment : Industrial electromagnetic environment
(EN/IEC 61326-1 Table 2)
• There may be cases that current output or voltage output fluctuate within 1%F.S
when a sensor is experienced electromagnetic interference under the condition of
the response time 30µs.
Others
• Do not attempt to dismantle, repair, or modify the product.
• Dispose of this product as industrial waste.

Warming Up
After turning ON the power supply, allow the product to stand for at least 10 minutes
before use. The circuits are still unstable just after the power supply is turned ON, so
measured values may fluctuate gradually.
A warmup of at least 10 minutes is also required after canceling LD-OFF input if LD-
OFF input is being used.
Sensing Object
The product cannot accurately measure the following types of objects: Transparent
objects, objects with an extremely low reflective sensor ratio, objects smaller than the
beam size, objects with a large curvature, excessively inclined objects, etc.
Mutual Interference
Inserting a calculating unit between amplifier units can prevent mutual interference
between two sensor heads.
Maintenance
• 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. If large dust particles adhere to the front filter of the sensor head,
use a blower brush (used to clean camera lenses) to blow them off. Do not blow the
dust away with your mouth. To remove smaller dust particles, use a soft cloth (for
lenses) with a small amount of alcohol. Take care not to wipe them off with exces-
sive force.
Scratches on the filter may cause errors.

When the power is turned ON, the model of Amplifier Unit (ZX2-LDA) will be displayed on
the main display and the channel number will be displayed on the sub-display.
Subsequently, the Sensor Head software version will be displayed on the main display
and the Amplifier Unit software version will be displayed on the sub-display.
These details are displayed for approximately five seconds, and then data for the RUN
mode will be displayed.

Installing the Amplifier Unit
Amplifier Units can be easily mounted to 35-mm DIN Track.
Installation Method
Hook the connector end of the Sensor Head on the DIN Track, and press in at the bottom
until the Amplifier Unit locks into place. If necessary, fix it in place by the End Plate.
DIN Track (Option)
PFP-100N (shallow type/1 m)

Amplifier Units and to prevent mutual interference between Sensor Heads.
The number of Amplifier Units that can be connected differs depending on the functions to
be used.
