About CCH →Documentation That Matches the Model.
Review applicable certificates, test reports and regulatory documents by product series. Safety ratings and compliance claims must be checked against the exact model and intended use.
ENT Light Curtains
Confirm the model’s documented safety classification, applicable standards and installation requirements.
SH27 Safety Scanners
Review the applicable functional-safety certificates, test documents and model scope.
YB27 Industrial LiDAR
Check electrical, EMC, market-specific and laser-product documentation for the selected model.
Safety Relay Modules
Verify supported inputs, output architecture and applicable documentation for the relay model.
Certificates, test reports and regulatory acknowledgments are distinct document types. A regulatory acknowledgment does not, by itself, constitute product approval. Machine-safety applications require a risk assessment and verification of the applicable model-specific documents.
Technical Resources & Downloads
