EMI Shielding Solutions for Robotics – Lightweight & Reliable

EMI Shielding Engineered for the Next Generation of Robots

Modern robots pack high-power motors, real-time controllers, vision systems, and wireless modules into compact, lightweight bodies. In electrically noisy environments—near VFDs, welders, or other robots—even minor EMI can disrupt:

Joint torque sensors → safety shutdowns
Camera/LiDAR data → navigation errors
EtherCAT/PROFINET/CAN bus → communication latency
Wi-Fi/Bluetooth → lost remote control

Konlida’s robotics-optimized EMI materials deliver high shielding performance without adding weight or rigidity, enabling reliable, safe, and certifiable robot operation in real-world industrial and commercial settings.

Unique EMI Challenges in the Robotics Industry

Challenge	Impact
Lightweight Plastic Housing	Lacks metallic shielding, leading to easy EMI leakage
High-Density Electronics Integration	Motors, controllers, and sensors are closely packed, causing severe crosstalk
Dynamic Moving Parts	Rigid shielding materials prone to fatigue and fracture under repeated motion
Non-Magnetic Requirement	Magnetic materials interfere with torque and Hall-effect sensors
Reliance on Wireless Communication	Wi-Fi 6 / BLE / UWB signals are vulnerable to internal noise interference

Konlida’s Robotics-Specific EMI Solutions

Collaborative Robots – Joints & Control Modules

Pain Points:

PWM noise from motors interferes with force-torque sensors, causing false emergency stops

Solutions:

Non-Magnetic Conductive Foam:

Magnetic permeability μr less than 1.01 — zero interference with sensitive sensors; Density less than 0.35 g/cm³ — adds negligible weight; High flexibility: withstands repeated bending (>1 million cycles tested)

Custom 3D-Conformable Gaskets:

Precisely fit complex curved cavities in robotic joints

Autonomous Mobile Robots – Main Controller & Battery Systems

Pain Points:

Motor noise disrupts LiDAR mapping and fleet communication in AGV/AMR

Solutions:

Low-Outgassing Conductive Elastomer:

Silicone-free formulation prevents contamination of optical sensors;
Compatible with IP65-rated sealing requirements

EMI Shielding Film for Battery Compartments:

Blocks BMS switching noise from radiating outward;
Thermal stability up to 125°C

Industrial Robotic Arms (6-Axis) – Servo Drive Units

Pain Points:

High-frequency noise from SiC-based drives couples into encoder feedback lines

Solutions:

High-Temperature Conductive Gasket:

Maintains stable contact resistance < 0.05 Ω under thermal cycling；
Resistant to gear oil and industrial cleaning solvents

EMI Gasket with Integrated Grounding Tab:

Simplifies grounding design and improves reliability

Service Robots & Specialized Robots (Medical / Security)

Pain Points:

Seamless aesthetic design limits available space for shielding; quiet operation is essential

Solutions:

Ultra-Thin (<0.2 mm) Conductive Fabric Tape:

Conforms easily to curved surfaces (e.g., robot head, torso)；
Acoustically quiet — no rattling or vibration noise during movement
