Data EMI Filters for 4...20 mA Analog Signals
Adobe-Plus-Datasheet.png

Long data lines from and to 4...20mA sensors and actuators "collect" plenty of noise which causes data misreading, errors and other malfunction.  OnFILTER' data EMI filters for such analog lines block EMI on long cables while providing pass through for the data.

We offer two models - for slow-changing signals (under 500 Hz) and for fast-changing signals (under 10 kHz).  The former provides the best noise suppression while the latter accommodates wider variety of sensors and actuators.  Data filters are small, unobtrusive and are easy to install and connect.
