The YGC1033 series is designed around a compact dual-pin shielded connector structure. Its combination of high power capability, compact construction, straightforward assembly, and environmental protection makes it suitable for high-voltage electrical connections where reliable power transmission and effective electromagnetic shielding are important. The YGC1033A-EV-S2PN/I-YW960 uses the same series design principles while providing a specific configuration for applications requiring this particular connector variant.

High-Voltage and High-Current EV Connector

The YGC1033A-EV-S2PN/I-YW960 is intended for high-voltage electrical architectures used in new energy vehicles. According to Yonggui's technical documentation, the YGC1033 series is mainly applied to electronic control and battery energy systems in new energy vehicles. These applications can include high-voltage battery connections, power distribution systems, electronic control units, and other vehicle electrical assemblies where a secure and durable power interface is required.

The connector supports a rated voltage of up to 1000V for the power circuit. The rated current depends on the applicable cable configuration. With a 35mm² shielded cable, the series is rated at up to 150A, while a 50mm² shielded cable configuration supports up to 200A. The technical specification also identifies a 3A rating for 0.5mm² or 0.75mm² unshielded cable applications. These values allow the YGC1033 platform to cover different electrical requirements while maintaining a compact connector format.

Dedicated YW960 Special Variant

The YGC1033A-EV-S2PN/I-YW960 is not simply a generic YGC1033A plug. It is separately identified in the manufacturer's ordering information as a dedicated special variant. The corresponding manufacturer product code is 112010104599. The technical specification lists this model as a 180° plug assembly, while the 120° and 90° plug variants are not specified for this particular YW960 configuration.

The model designation should therefore be retained when selecting a replacement or designing a cable assembly. Because connector configurations can differ in mechanical interface, keying, cable compatibility, and accessory requirements, buyers should verify the exact part number against the existing vehicle or electrical system before ordering.

Dual-Pin Shielded Construction

The YGC1033 connector family uses a dual-pin shielded construction intended for high-power electrical applications. Shielding is an important feature in modern electric vehicles because high-voltage power circuits can generate electromagnetic interference that may affect nearby electronic systems. The plug housing uses an aluminum alloy construction with a passivation process and provides 360° shielding around the connector interface.

The manufacturer specifies the plug housing material as ADC12. The aluminum alloy housing and passivated surface are designed to provide enhanced environmental resistance, including resistance to salt-spray exposure. The documentation specifies a standard neutral salt-spray test of 96 hours, with 240-hour, 480-hour, and 960-hour levels also identified in the material and salt-spray specification. This makes the connector platform suitable for vehicle environments where moisture, road contaminants, and corrosive conditions may be encountered.

Reliable Environmental Protection

Environmental protection is a key consideration for EV high-voltage connectors. The YGC1033 series plug and receptacle meet IPXXB requirements before mating. After normal mating and locking, the connector assembly achieves IP67, IP6K9K, and IP68 protection according to the manufacturer's technical specification. The IP68 condition is specified for immersion at a water depth of 1 meter for 24 hours.

This level of protection helps the connector withstand water, dust, and challenging operating environments when properly assembled and locked. For electric vehicle applications, this is particularly useful in battery compartments, power distribution areas, and other locations where connectors may be exposed to water splash, dust, cleaning processes, or temporary immersion.

Wide Operating Temperature Range

The YGC1033 series is specified for an operating temperature range of -40°C to +125°C. This wide temperature range is appropriate for automotive electrical systems that may experience substantial temperature variation during vehicle operation, charging, parking, and exposure to external weather conditions.

The specified relative humidity range is up to 90% at 40°C. The connector materials also incorporate a UL94 V-0 flame-retardant rating. Together, these characteristics support the use of the YGC1033 connector platform in demanding electrical environments where temperature, humidity, and fire-safety considerations must be addressed.

Electrical Insulation and Withstand Performance

The YGC1033 series provides high insulation performance for both the power and signal circuits. The technical specification gives a withstand voltage of 3000V for the power circuit and 1000V for the signal circuit under normal 50Hz AC test conditions, with leakage current specified at no more than 5mA.

The documented insulation resistance is at least 5000 MΩ for the power circuit and at least 1000 MΩ for the signal circuit under normal conditions. These electrical characteristics are important for high-voltage vehicle systems because adequate insulation helps reduce the risk of unwanted leakage and electrical breakdown between conductive elements and surrounding structures.

An HVIL function is available as an option. High Voltage Interlock Loop functionality can be used in vehicle high-voltage systems to help monitor the connector and high-voltage circuit condition. Whether HVIL is included should be confirmed according to the required connector configuration and vehicle system design.

Cable Compatibility and Assembly Considerations

One important consideration when purchasing the YGC1033A-EV-S2PN/I-YW960 is that certain plug components are ordered separately according to the wiring specification. The manufacturer's documentation provides different accessory configurations for 35mm² and 50mm² shielded cables, including standard shielded cables and LV216 shielded cable options.

For example, the YGC1033A 180° plug accessory configuration supports 35mm² shielded cable with an outer diameter of approximately 14.6 to 15.4 mm. A 35mm² LV216 shielded cable configuration is also listed. For 50mm² applications, the documentation specifies shielded cable with an outer diameter of approximately 17.5 ± 0.5 mm, while the 50mm² LV216 configuration uses a cable outer diameter of approximately 15.8 - 0.6 mm.

The appropriate socket assembly, shielding sleeves, cable seal, rear cover, and related components should therefore be selected according to the actual cable specification. This modular accessory approach allows the YGC1033 connector family to accommodate different cable constructions while maintaining the required sealing and shielding performance.

Mechanical Durability

The YGC1033 series is specified for a mechanical life of 50 mating cycles. The connector is designed for secure mating and locking, providing a stable electrical and mechanical connection during vehicle operation. The compact connector structure also helps simplify installation in applications where available packaging space is limited.

The series includes different plug configurations, including straight and angled versions, but the YGC1033A-EV-S2PN/I-YW960 is specifically identified as a 180° straight plug assembly. Its dedicated configuration makes it suitable where a straight cable outlet and the YW960 special variant are required.

Applications in EV and Battery Systems

The YGC1033A-EV-S2PN/I-YW960 is primarily suited to high-voltage electrical applications in electric and new energy vehicles. Typical application areas may include battery power systems, battery distribution assemblies, vehicle power electronics, electronic control systems, and other high-current electrical interfaces.

Its 1000V power rating, high-current capability, shielded construction, environmental sealing, and broad operating temperature range make the YGC1033 platform suitable for the electrical architecture of modern electric vehicles. The connector can also be considered for related high-voltage battery and energy-system applications where the specified mechanical and electrical interface is required.

Ordering and Replacement Notes

When sourcing the YGC1033A-EV-S2PN/I-YW960, buyers should pay particular attention to the complete model designation rather than selecting a connector solely by the YGC1033A family name. The YW960 suffix identifies the specific special variant, while the S2PN/I designation describes the connector configuration. The manufacturer's ordering information identifies 112010104599 as the corresponding product code.

Because the plug components may need to be selected separately according to cable specifications, it is recommended to confirm the cable cross-sectional area, cable construction, cable outer diameter, required shielding components, and mating interface before placing an order. If the connector is being used as a replacement part, matching the original part number and configuration is especially important.
