UL approval file 224618
CE compliant acc. to EMC guideline 2014/30/EU
RoHS guideline 2011/65/EU
An independent test laboratory (TTI-P-G115/96-01) 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.
