Technical Features of Rectangular Connector 6-146762-0: A Comprehensive Analysis

As a core component enabling board-to-board and wire-to-board connections in electronic systems, rectangular connectors directly determine system stability and reliability. Among TE Connectivity's product portfolio, the AMPMODU Mod IV series connector (Model 6-146762-0) stands out as a preferred solution for industrial control, telecommunications equipment, and automotive electronics due to its unique technical design. This article delves into the product's technical features from four dimensions: structural design, electrical performance, environmental adaptability, and compliance.

1. Modular Structural Design: Balancing Compactness and Scalability
The 6-146762-0 employs a dual-row 6-position vertical board-to-board configuration with a 2.54mm (0.1-inch) pitch and an overall height of just 8.13mm, enabling high-density connections in limited spaces. Its modular characteristics include:

Contact Type: Female socket design supports precise mating with male pins, featuring a 3.18mm contact length to ensure stable signal transmission.
Termination Method: Solder termination compatible with wave soldering temperatures up to 240°C, facilitating automated production. The push-pull latching mechanism allows tool-free assembly, reducing maintenance costs.
Scalability: Stackable design enables multi-board layering to expand signal transmission channels, catering to complex circuit layouts.
2. High-Performance Electrical Characteristics: Ensuring Signal Integrity
In high-speed data transmission and high-current applications, the 6-146762-0 demonstrates superior electrical performance:

Rated Parameters: Supports 2A rated current, 5,000MΩ insulation resistance, and 750Vrms dielectric withstanding voltage, eliminating breakdown risks in high-voltage environments.
Signal Integrity Optimization: Tin-plated contacts (3.81μm thickness) minimize contact resistance to milliohm levels while suppressing oxide layer formation, extending service life.
Impedance Matching: Optimized square contact geometry and pitch reduce signal reflection and crosstalk, making it suitable for differential signal transmission.
3. Harsh Environment Adaptability: Industrial-Grade Reliability Assurance
The connector withstands extreme conditions like vibration, high temperatures, and corrosion through material and process innovations:

Temperature Range: Operates from -65°C to 125°C, suitable for automotive electronics and industrial control applications with severe temperature fluctuations.
Material Selection: Glass-fiber-reinforced polyester (UL94 V-0 flame retardant) for the insulator and phosphor bronze for contacts ensure mechanical strength and conductivity.
Protective Design: The black housing provides dust and moisture resistance, ideal for outdoor telecommunications equipment or humid industrial environments.
4. Full-Cycle Compliance: Meeting Global Market Access Requirements
As a global supplier, TE Connectivity adheres strictly to international environmental and safety standards. The 6-146762-0 demonstrates compliance through:

EU RoHS/ELV Directives: All homogeneous materials contain restricted substances (e.g., lead ≤0.1%, cadmium ≤0.01%) below regulatory limits, eliminating additional labeling requirements for EU market entry.
REACH Regulation: Substances of very high concern (SVHC) comply with ECHA guidelines, mitigating supply chain risks from chemical non-compliance.
Industry Certifications: UL-certified (File No. E28476) for North American safety compliance and CSA LR7189-compliant for Canadian market access.
5. Application Scenarios and Market Value
The connector's technical advantages make it indispensable in the following fields:

Industrial Automation: Facilitates high-speed signal transmission between control and power boards in PLCs and servo drives, improving system responsiveness.
Telecommunications: Used in backplane connections for base stations and routers, supporting 5G infrastructure's high-density wiring demands.
Automotive Electronics: Withstands vibration and temperature shocks in in-vehicle entertainment systems and battery management systems (BMS), ensuring long-term reliability.
Conclusion
The rectangular connector 6-146762-0 establishes a technical edge through modular design, high-performance electrical parameters, harsh environment adaptability, and full-cycle compliance. Its "compact size, high reliability, and easy scalability" characteristics resolve the contradiction between miniaturization and high performance in electronic devices. Leveraging TE Connectivity's global supply chain, the product provides standardized connectivity solutions for industrial, telecommunications, and automotive sectors. With the proliferation of smart manufacturing and IoT technologies, market demand for such connectors will continue growing, and the 6-146762-0's technological evolution and ecosystem expansion may further consolidate its leadership in premium markets.
