Built by a national high-tech enterprise with ISO certifications, this connector guarantees performance where data integrity and mechanical durability are paramount.
Jihongfa Electronics leverages its expertise in precision Connector Manufacturing—spanning SATA, USB3.0, and OBD products—to deliver this robust solution. It is an ideal choice for system designers and engineers requiring a dependable, standards-compliant interface for data-intensive and Industrial Applications.
The SFF-8611 4X Clip-Mount Female Connector is a board-mountable female header conforming to the SFF-8611 mechanical and electrical specification. The "4X" designation indicates it supports four data lanes, typically used for a single-port SAS 2.0/3.0 or SATA III connection. The clip-mount design features integrated retention clips that securely fasten the connector to the PCB upon insertion, providing enhanced mechanical stability compared to standard press-fit or solder-only mounts. This makes it particularly suitable for applications subject to vibration, shock, or frequent mating cycles.
This connector is a fundamental building block for creating reliable data pathways in systems where the storage or communication interface must remAIn secure under operational stress. It is manufactured by Jihongfa Electronics, a company with a proven track record in supplying connectors for computers, new energy vehicles, and communication devices.

Test & Measurement Equipment: Internal storage interfaces in rugged portable or benchtop instruments.
Q1: What is the primary advantage of the clip-mount design?
A: The clip-mount (夹板) design provides superior mechanical retention to the PCB. It prevents the connector from loosening or becoming dislodged due to vibration, shock, or repeated cable mating cycles, which is crucial in industrial or mobile applications.
Q2: Can this 4X connector be used for dual-port SAS drives?
A: No. A standard dual-port SAS connection requires 8 lanes (8X). This 4X connector is designed for a single-port SAS or a single SATA device connection.
Q3: What do the different pin materials (7P Phosphor Bronze, 15P Brass) indicate?
A: This is a common design. The 7 signal pins are made from phosphor bronze for its excellent spring properties and electrical conductivity for high-speed signals. The 15 power pins are made from brass for its good current-carrying capacity and mechanical strength at a lower cost.
Q4: Is this connector lead-free and RoHS compliant?
A: While the provided notes specify tin plating on solder tails, full material declarations and RoHS compliance should be confirmed with Jihongfa Electronics. As a modern manufacturer serving global markets, their products are typically designed to meet RoHS directives.
Q5: What is the operating temperature range?
A: The specific operating temperature range depends on the housing material. Please consult Jihongfa's detailed datasheet or contact them directly for this specification, which is vital for industrial applications.
Q6: Do you offer mating male connectors or cable assemblies?
A: Yes, as a full-service connector company also producing wire harnesses, Jihongfa can typically provide the mating male connectors (e.g., SFF-8611 to SATA/SAS drive connectors) and complete cable assemblies.
