Laser Safety; Requirements From Regulations And Standards - Omron ZX Datasheet

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.

Attenuator Not required
Location controls Not required
Viewing optics Emission from all viewing systems must be below Class 1 AEL's as applicable
Scanning Scan failure shall not cause product to exceed its classification
Class label Required wording
Aperture label Not required
Service entry label Required as appropriate to the class of accessible radiation
Override interlock label Required under certain conditions as appropriate to the class of laser used
User information Operation manuals must contain instructions for safe use
Purchasing and service Promotion brochures must reproduce classification labels; service manuals must contain safety information
information
Medical products Special calibration instructions required
Fibre optic 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.
