Surface Mount Push-Push Micro SD Interface Socket

Nintendo Switch Card Connector's Product Introduction

KKG Electronics presents the TF-4462, a precision-engineered micro sd connector designed to facilitate external storage expansion in compact electronic devices. This component utilizes a "push-push" internal spring mechanism, providing tactile feedback and securing the card firmly during operation, then ejecting it with a simple press. As a high-performance memory card connector, it is built with high-temperature thermoplastics to withstand SMT reflow soldering processes. The design incorporates a robust metal shell that shields against electromagnetic interference while adding mechanical strength to the micro sd card socket. With its integrated card detection switch, the system can instantly recognize media insertion. Ideally suited for mobile devices and industrial loggers, this micro sd socket ensures stable connectivity and data integrity for SDIO and SPI communication protocols.

Nextbase 622GW TF Card Connector's Product Operating Principle

Push-Push Ejection: The connector contains an internal cam and spring mechanism where the user pushes the card in to lock it effectively and pushes it again to release the spring and eject the media.
Electrical Engagement: As the card slides into the housing the flexible gold-plated contact beams wipe against the card pads to remove oxidation and establish a low-resistance data path.
Card Detection: A mechanical leaf switch located at the rear of the housing is physically depressed when a card is fully inserted sending a logic signal to the main processor to initialize the driver.

Raspberry Pi 4 Model B Card Connector's Product Functions

Storage Expansion: Provides a physical interface that allows users to upgrade device storage capacity dynamically using standard Micro SD cards.
Data Transmission: Facilitates high-speed bidirectional data transfer between the removable flash memory and the device host controller via SPI or SD bus protocols.
Media Retention: Secures the memory card against vibration and accidental removal ensuring data is not corrupted by sudden disconnections during write operations.
Hot Swapping Capability: Enables the safe insertion and removal of memory cards while the device is powered on facilitated by the card detect switch and specific pin contact sequencing.

Action Cameras: Integrated into the mainboard of the GoPro HERO11 to record high-bitrate 5K video footage to removable storage.
Single Board Computers: Used on the bottom of the Raspberry Pi 4 Model B to house the operating system boot drive.
Dash Cams: Located on the side of the Nextbase 622GW Dash Cam to continuously loop record driving incidents.
Handheld Consoles: Integrated into the expansion slot of the Nintendo Switch to allow players to download and store digital games.

We ensure high production efficiency and ship your order within 7 days after payment.

Q1: What is your typical production lead time?

A: For most standard orders, our production lead time is approximately 2 to 3 weeks. This can vary based on order volume, component complexity, and current capacity. We will always provide a confirmed delivery timeline with your order.

Q2: What is your policy on small volume orders?

A: We support projects of all scales, from startups to large-scale production. While we can accommodate smaller orders (e.g., 1,000-2,000 pcs), please note that larger volumes typically provide greater cost efficiency in terms of unit price and shipping charges.

Q3: Do you offer custom design and tooling services?

A: Yes, custom engineering is a core strength at KKG Electronics. Our R&D team is fully equipped to develop new tooling for unique components or execute application-specific modifications to our existing product lines. Let's discuss your design goals.

Q4: What file formats are needed for a technical quotation?

A: To ensure accuracy, please provide the following files:

For PCB Quotations: Gerber files and a document detailing all technical requirements.

For PCBA Quotations: Gerber files, a complete Bill of Materials (BOM), and any specific function test procedures.

For Custom Components: CAD files or AI format artwork are preferred.

Q5: What are your accepted payment terms?

A: Our payment terms are designed for flexibility. We accept T/T (Telegraphic/Bank Transfer) for bulk production orders. For sample requests and smaller volume orders, payment via PayPal is available for your convenience.
