NINGBO KEYONG JINGSHENG ELECTRICAL APPLIANCE CO., LTD. presents the Shrouded Type Automotive Relay KLDF (V8) Plug-In PCB Mini ISO Relay, designed for 60A high-current switching in automotive and lamp accessory applications. It supports PC pin, quick connect, and PCB mounting, with dustproof and sealed options for improved reliability. The compact Mini ISO structure ensures easy integration, while optional diode, reverse diode, or resistor configurations enhance circuit protection. With a shrouded housing, standard ISO terminal, and -40°C to 125°C operating range, it delivers stable performance and long service life. Manufactured by KEYONG, a professional relay manufacturer in China, this RoHS-compliant relay is a cost-effective solution for automotive and industrial power systems.
A shrouded type automotive relay is a relay with a protective cover structure designed to isolate and protect internal contacts from dust, moisture, and external contamination. This design significantly reduces the risk of short circuit, arcing damage, and contact failure, making it suitable for critical automotive electrical systems.
Compared with standard relays, the shrouded design enhances:
●Electrical safety
●Mechanical durability
●Environmental resistance
In automotive applications, relays are exposed to vibration, heat, and electrical load variations. A shrouded structure helps to:
●Prevent dust and contamination from entering contact points
●Reduce risk of electrical arcing and failure
●Improve insulation performance
●Extend relay lifespan under continuous operation
For OEM manufacturers and automotive system integrators, this design significantly improves system reliability and safety compliance.
