1.5mm Female Connector (Part Number: 7283-5539-40) The 1.5mm female connector (part number 7283-5539-40) is a compact, precision-engineered electrical connector designed for secure and reliable signal or power transmission in low-current applications. With a pitch of 1.5mm, this connector is ideal for space-constrained environments where miniaturization is critical, such as automotive electronics, consumer devices, industrial control systems, and telecommunications equipment. Key Features 1. Compact Design The 1.5mm pitch ensures a high-density connection, making it suitable for applications where PCB real estate is limited. The female connector is designed to mate with corresponding male terminals or headers, providing a stable and vibration-resistant connection. 2. Secure Locking Mechanism Many 1.5mm female connectors feature a locking clip or friction-based retention system to prevent accidental disconnection, ensuring durability in high-vibration environments like automotive or industrial settings. 3. High-Quality Materials The connector is typically constructed from high-temperature-resistant thermoplastics for the housing, ensuring long-term reliability under thermal stress. The contacts are often made of phosphor bronze or brass with tin or gold plating to enhance conductivity and corrosion resistance. 4. Wiring Compatibility This female connector is compatible with 1.5mm² (or similar gauge) wires, secured via crimping, insulation displacement, or soldering, depending on the variant. The crimp-style terminals ensure a gas-tight connection for optimal electrical performance. 5. Electrical Specifications - Voltage Rating: Typically rated for 50V–250V AC/DC, depending on insulation and contact materials. - Current Rating: Designed for low to moderate currents, usually 3A–5A per contact. - Temperature Range: Operates reliably between -40°C to +105°C (may vary based on material). 6. Applications - Automotive Electronics: Used in sensors, infotainment systems, and lighting controls. - Consumer Electronics: Found in small appliances, wearables, and IoT devices. - Industrial Equipment: Deployed in control panels, PLCs, and robotic systems. Installation & Handling - Ensure proper alignment when mating with male headers to avoid bent pins. - Use appropriate crimping tools for secure wire termination. - Avoid excessive mechanical stress on the connector to maintain long-term reliability. This 1.5mm female connector offers a balance of durability, precision, and space efficiency, making it a versatile choice for modern electronic interconnects.
