Harting Connectors: Protection against EMI Interference
Designing for high-powered installations often requires accounting for a variety of risks, including electromagnetic interference. This is a common occurrence in installations where low-level signals and high-speed data are in close proximity within control cabinets.
Harting has a range of housing options designed to support electromagnetic compatibility at the system level and minimise EMI within the overall connector/cable/enclosure system.
The Harting range deploys two shielding features within its designs to provide resistance to EMI;
Nickel-coated zinc die-cast housings.
- Nickel coating provides a highly conductive, corrosion-resistant outer layer that intercepts incoming radiation and safely grounds stray currents away from internal contacts.
Labyrinth Geometry composition
- The profile of the connectors is designed to feature multi-angled paths that help reduce EMI ingress, maintaining shielding continuity. Additionally, housings feature 360° overlapping contact points, reducing gap voids and preventing high-frequency radiation from passing through.
Electrical designers can select from a range of Harting products depending on their specific needs, with EMI-protected housing options for the following;
Han A EMC & Han B EMC Connectors
- Designed for standard- to heavy-duty industrial applications, these connectors are suited for compact installations where space is limited.
Han High Performance Railway (Han HPR)
- Designed for extreme environmental conditions of high vibration, weather, and dust, the HPR series meets maximum shielding requirements for railway traction systems and outdoor high-power distribution.
Han HP Direct
- Designed specifically for panel wall mounting with sealing gaskets maximising continuous conductive area for demanding EMC applications.
If you’re an electrical designer, whether designing control cabinets or larger switchboards with dense data and power areas, the Harting range of EMI-protected connectors can help improve shielding continuity at the point of connection.
Please be advised that Harting connectors can only provide EMI protection at the point of connection, and appreciation for EMI protection in cabling, cable termination, and glands must be taken into account to protect the system from electromagnetic interference.
