EMI SHIELDING SOLUTION IN TRANSPORTATION

AC/DC CHARGING

In the dynamic and ever-evolving electric vehicle (EV) industry, it is imperative to partner with an experienced EMI/RFI shielding manufacturer that specializes in crafting tailored solutions for intricate and cutting-edge components.

At TE, our expertise in the production of customized EMI/RFI shielding components. Our extensive expertise in delivering custom solutions for electromagnetic interference (EMI) and radio-frequency interference (RFI) mitigation enables us to collaborate seamlessly with your design team.

We offer valuable input on dimensional precision, tolerance specifications, and the selection of optimal raw materials to deliver cost-effective and efficient shielding solutions.

SHIELDING TYPE	APPLICATION	FEATURES	BENEFITS
Conductive ½ wrap	Panel Enclosure	• Closed cell sponge with conductive fabric wrapped around 1 edge • Can be provided as a fabricated gasket	• Will provide a combined EMI and environmental seal • Low closure force
Knitted Wire Mesh		• The mono-filament interlocking loop construction gives strength while allowing it to confirm to almost any size or shape. • A selection of elastomer cores are available to meet conditions such as temperature range, compression set, compression force	• Delivers good galvanic match with mating flanges, thereby limiting the possibility of corrosion between gasket and flange. • Excellent radio frequency interference (RFI)/electromagnetic interference (EMI) shield between two metallic surfaces
EMI Vents		• Hi-impact ABS UL94V-0 fire retardant moulding thick aluminum honeycomb and a nickel/copper fabric gasket to ground the honeycomb to the metalwork	• Deliver good air flow is required for cooling and ventilation but where EMC compliance must be ensured

OTHER TRANSPORTATION APPLICATIONS

ADVANCED DRIVER ASSISTANCE SYSTEMS (ADAS)

Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) pose threats to electronic signal integrity and strength, leading to disruptions and suboptimal performance in sensitive communication systems and devices. In the context of Advanced Driver Assistance Systems (ADAS), EMI becomes a critical safety concern. To mitigate these issues, robust engineering design is essential.

Vehicles with advanced driver assistance systems (ADAS) include a wide range of electronics, many of which have a high risk of propagating EMI. Numerous design best practices exist to address electronic noise, and while engineers might lack significant control over the electrical systems, there are still a few design considerations that can minimize the impact of electromagnetic interference (EMI) on sensors and software.

It is critical to consider EMI/RFI shielding solutions that effectively reduce susceptibility to electronic malfunctions by either blocking external electromagnetic waves or preventing the emission of internal electromagnetic waves that could interfere with surrounding circuits or devices in and around ADAS components.

SHIELDING TYPE	APPLICATION	FEATURES	BENEFITS
Form-in-Place	Housing Seal	• Elastomer compound dispensed directly onto hardware • EMI shielding and/or environmental seal for dust and moisture	• Suited to applications where small intricate EMI gasket profiles are required • Can reduce assembly costs • Low closure force
Conductive elastomer	Camera, Radar and Data Module Seal	• Silicone or fluorosilicone loaded with highly conductive particles providing superior EMI shielding performance combined with excellent environmental sealing.	• Material options to provide required EMI performance and galvanic compatibility • Provides low contact resistance between mating surfaces
