UL approval File 224618
CE compliant acc. to EMC guideline 2004/108/EC
RoHS compliant acc. to guideline 2002/95/EC
An independent test laboratory (TTI-PG115/96-01) approved by the German
Accreditation Council (DAR) certified the compliance with the Railways Stand-
ard,
according to EN 50121. This means our encoder is compatible with higher
electromagnetic noise standards than standard industrial encoders.
You will have a higher quality encoder even in applications with higher EMC
noise levels. We will gladly send you a copy of the test report on request.
When ordering an encoder to the railway standard, please ensure you state this
explicitly on the order.
Mounting accessory for shaft encoders Order-No.
Coupling Bellows coupling ø 15 mm [0.59“] for shaft 4 mm [0.16“] 8.0000.1201.0404
