The XY142-04F is a robust, high-current square female connector engineered for secure and reliable wire-to-board or wire-to-wire connections in demanding power and multi-line applications. Designed with a generous 6.2mm pitch, this connector system is optimized for applications requiring substantial power delivery and connection integrity. A key feature of the XY142-04F is its integrated Release-Lock mechanism, which ensures a positive, secure mating connection that resists accidental disengagement due to vibration or shock, a critical requirement for industrial, appliance, and high-power consumer electronics.

Key Features and Construction

The connector housing is constructed from Nylon UL94V-2, a material selected for its excellent balance of mechanical strength and flammability resistance, ensuring safe operation within various environments. The distinctive white color of the housing aids in visual identification and assembly.

At the core of the XY142-04F's performance are its high-quality contacts. The connector is configured as a 4-way female receptacle with 4 individual pins, ideal for four-line power or power-and-signal circuits. The contacts themselves are made from Phosphor Bronze, a material known for its superior spring properties and resistance to fatigue, ensuring consistent contact force over many mating cycles. To enhance conductivity and protect against corrosion, the contacts feature a Tin Plated finish.

Electrical Specifications for Reliable Performance

The XY142-04F is rated for significant power and voltage, capable of handling an Electrical Rating of 11A at 300VAC. This high current and voltage rating makes it suitable for heavy-duty power applications where four lines are required.

The connector's electrical performance is further defined by its stringent specifications:

• Contact Resistance: A maximum of 10 m ensures minimal power loss and heat generation across the connection, contributing to overall system efficiency, especially under high load.
• Insulator Resistance: A minimum of 1000 M guarantees excellent isolation between adjacent contacts, preventing short circuits and maintaining signal purity.
• Dielectric Strength: The connector can withstand an applied voltage of AC 1500V for 1 minute, confirming its high-voltage isolation capability and reliability under transient conditions.
