WEIPU ShieldGuard™ Shielded Circular Connector — EMI-Protected Industrial Connector

The WEIPU ShieldGuard™ Shielded Circular Connector is an EMI-protected industrial connector family engineered for high-reliability signal and power connections in electrically noisy environments. Key features include 360° conductive shielding for superior EMI/RFI suppression, robust circular metal and polymer housings for IP69K-level ingress protection, multiple contact arrangements for signal, power and hybrid requirements, secure locking mechanisms to resist vibration, and materials rated for extended temperature ranges. Designed and manufactured by WEIPU, the product follows rigorous quality standards and is optimized for demanding industrial use.

EMI protection in the ShieldGuard™ design is achieved through a continuous conductive shell, shielded backshells, and properly grounded contact terminations that form an effective barrier against radiated and conducted interference. In many variants, internal metal gaskets and integrated drain contacts ensure the shield is maintained across the cable-to-connector transition. This protection matters because it preserves signal integrity for sensors, drives, communications and control systems, reduces downtime caused by electromagnetic interference, and helps meet industry EMC requirements in applications such as automation, renewable energy and rail.

ShieldGuard™ Shielded Circular Connectors are ideal for mission-critical industries that require EMI mitigation and robust environmental protection: industrial automation and robotics, factory and process control (Industry 4.0), renewable energy inverters and converters, rail transit and rolling stock, automotive test rigs and EV infrastructure, medical equipment with sensitive electronics, and harsh outdoor installations. Their combination of shielding, IP69K ingress protection, and high mechanical reliability makes them suitable wherever clean signals and durability are essential.

ShieldGuard™ families offer multiple contact layouts for power, signal and hybrid configurations, a range of current ratings (including high-current options supported by WEIPU technology), cable- and panel-mount styles, and materials compatible with washdown and autoclave processes where required. Standard performance highlights from WEIPU’s product portfolio include IP69K protection, high-current variants up to industry-leading levels, long mating-cycle durability, and temperature ratings for industrial environments. WEIPU supports OEM/ODM customization (overmolding, special contact plating, filtered inserts, keyed shells) and rapid prototyping—typically 7–15 days—so you can tailor a Shielded Circular Connector to specific electrical, mechanical and environmental requirements.
