Each of these listed components has a quantity of two in the corresponding component configuration.
Shielding and Connector Construction
The YGC1033 series is designed as a shielded connector system. According to the technical specification, the plug housing is made from ADC12 material and uses an aluminum-alloy passivation process. The design provides 360° shielding and is specified for high salt-spray resistance. This construction is part of the series design intended for high-voltage and high-current applications in new energy vehicle electrical systems. The specification separately identifies the receptacle shell as PA66-GF30 in black, while the plug housing is specified as ADC12.
The connector system also provides environmental protection when the plug and receptacle are properly mated and locked. The technical data specifies IP67, IP6K9K, and IP68 protection in the mating configuration. The IP68 condition is specified for immersion at a water depth of 1 meter for 24 hours. When the receptacle is mated with its dust cover, the specified protection rating is IP3X. The plug and receptacle themselves meet the IPXXB requirement before normal mating and locking.
Electrical Characteristics
The YGC1033 series provides separate power and signal electrical specifications. The rated current depends on the compatible cable configuration. The technical specification gives 150 A for 35 mm² shielded cable and 200 A for 50 mm² shielded cable. For 0.5 mm² or 0.75 mm² unshielded cable, the specified rated current is 3 A. For the power circuit, the rated voltage is 1000 V, while the signal circuit is rated at 24 V.
The specified withstand voltage is 3000 V for the power circuit and 1000 V for the signal circuit under normal 50 Hz AC conditions. The specified leakage current is no more than 5 mA. The document also gives insulation resistance values of at least 5000 MΩ for the power circuit and at least 1000 MΩ for the signal circuit under normal operating conditions. An HVIL function is available as an optional feature. These electrical parameters form part of the general YGC1033 series specification and should be considered together with the selected cable and mating components.
Mechanical and Environmental Characteristics
The specified mechanical life of the YGC1033 connector series is 50 mating cycles. The operating temperature range is -40°C to +125°C, while the specified relative humidity is no more than 90% at 40°C. The connector system has a UL94 V-0 flame-retardant rating. These environmental specifications define the conditions provided by the technical specification for the connector family and are applicable to system design and component selection.
The plug housing is specified as ADC12 and is associated with neutral salt-spray testing of 96 hours, with the technical document also referencing 240-hour, 480-hour, and 960-hour test levels. The receptacle shell uses black PA66-GF30. Together with the shielded construction and passivation treatment of the plug housing, these material and environmental characteristics are intended to support the connector's specified application conditions.
