100 Series

Technical Bulletins

Our 100 Series of technical bulletins will give you specific information about EPC encoders, and guidance in specifying the right encoders and accessories for your applications.


When to Choose the CE Mark 

The CE (Conformite European) mark indicates that a product complies with any or all of the European Union (EU) directives, and will affect you only if your system is to be sold in Europe.
