General information

With the innovative EMC platform approach, this enables customers to select their optimum filter requirements, contact per contact. Allowing not only to segregate the filtering per contact but also to mix the type of filter used. This is then cast in a single competitive product (in a standard D-Sub shell).

The biggest advantage of the HARTING technology is that multiple filter assemblies can be configured to create different filter designs: C, Pi, L and T types. Since any value of capacitor can be placed on any contact, a wide range of configurations can be built, it is even possible to have an individual pin unfiltered if necessary.

Furthermore, Pi filters can be supplied in a standard connector size shell. In addition, protection against lightening and transient voltage can be included upon request.

  • C filter

  • L filter

  • Pi filter

  • ESD protection

  • Lightening protection

  • Combination

With any capacitance on any pin in a standard D-Sub shell.
