SMT Standard SD Connector with Push-Push Ejection

ResMed AirSense 10 SD Card Connector's Product Introduction

KKG Electronics presents the SD-2652, a professional-grade interface designed to accommodate full-size Secure Digital (SD) memory cards. While the industry often trends toward the smaller micro sd connector, this Standard SD socket remains the preferred choice for industrial and professional equipment where card handling durability is paramount. It functions as a robust memory card connector, featuring a smooth "push-push" mechanism that securely locks the card in place and ejects it with a tactile click. Unlike a typical micro sd card socket, this unit incorporates a physical Write Protect switch, adding a layer of hardware-level data security. The housing is constructed from high-temperature thermoplastics to withstand SMT reflow. As a heavy-duty alternative to a delicate micro sd card connector, the SD-2652 ensures reliable 9-pin data transmission and mechanical stability for critical recording devices.

Canon EOS 5D Mark IV SD Card Connector's Product Principle

Push-Push Ejection: The connector utilizes an internal spring and cam system where the user pushes the SD card inward to latch it into the read/write position and pushes it again to release the lock for removal.
Switch Activation: Upon insertion the card physically depresses the Card Detect lever to signal the CPU while the Write Protect sensor reads the position of the slide tab on the card casing.
Contact Engagement: As the card slides into the housing the nine precision-stamped gold-plated contacts wipe against the card pads removing surface oxidation to establish a secure data path.

Medical Equipment: Integrated into the data slot of the ResMed AirSense 10 CPAP machine to record patient sleep therapy data on a removable Standard SD card.
3D Printers: Used on the control interface of the Creality Ender 3 V2 to allow users to load G-code print files directly from a robust SD card.
Digital Photography: Located in the memory slot of the Canon EOS 5D Mark IV DSLR to handle the high-speed data throughput required for 4K video and RAW image capture.

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.
