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.

Designed to prevent removal of the panel until accessible emission values are below the AEL (see note 2) for the class
assigned
Remote control
Not required
Permits easy addition of external interlock in la-
ser installation

Gives audible or visible warning when laser is
switched on or if capacitor bank of pulsed laser
is being charged
Attenuator
Not required
Not required
Gives means beside ON/OFF switch to tempo-
rarily block beam
Location controls
Controls so located that there is no danger of exposure to AEL above
Classes 1 or 2 when adjustments are made.
Viewing optics
Scanning
Emission from all viewing systems must be below Class 1 AEL’s as applicable
Scan failure shall not cause product to exceed its classification

Cable service connections require tool to disconnect if disconnection breaks protective housing and permits access
above Class 1
*With respect to the requirements of remote interlock connector, key control, emission warning and attenuator, Class 3B laser products not
exceeding five times the AEL of Class 2 in the wavelength range of 400 nm to 700 nm are to be treated as Class 3A laser products.
