Compact Push-Eject Memory Card Interface

DJI Mavic 3 TF Card Connector's Product Introduction

KKG Electronics presents the TF-2162, a high-performance card socket designed for modern mobile and embedded devices. This component utilizes a sophisticated "push-push" mechanism, ensuring the media is securely locked during operation and easily ejected with a soft press. As a premium memory card socket, it is constructed with high-temperature thermoplastics to withstand SMT reflow soldering. The interface ensures high-speed data transmission through precision gold-plated contacts. While engineers often search for a sim connector or sim socket for communication, this device is specifically engineered for TransFlash storage expansion. Its robust metal shell provides EMI shielding and structural reinforcement. The unit includes an integrated card detection switch, allowing the host processor to manage power states efficiently when media is inserted or removed.

70mai A800S TF Card Connector's Product Operating Principle

Push-Push Ejection: The connector features an internal cam track and spring system where pushing the card in locks it effectively and a second push releases the latch to eject the card.
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 secure data path.
Presence Detection: A mechanical card detect switch located at the side is physically depressed by the inserted card sending a signal to the MCU to initialize the driver.

Analogue Pocket TF Card Connector's Product Functions

Storage Interface: Acts as the physical bridge for SPI or SDIO communication protocols allowing the device to read and write data to external flash memory.
Mechanical Retention: Secures the media card against vibration and shock preventing data corruption caused by intermittent contact during operation in portable devices.
Hot-Swap Capability: Facilitates the safe insertion and removal of storage media while the device is powered on managed by the specific pin sequencing.
EMI Shielding: The stainless steel cover provides structural reinforcement and connects to the PCB ground pads to shield high-speed data signals from interference.

Surveillance Drones: Integrated into the fuselage of the DJI Mavic 3 to provide high-speed onboard storage for 5.1K video capture.
Single Board Computers: Used on the expansion slot of the Orange Pi 5 to house the operating system or extra data storage.
Dash Cameras: Located on the side of the 70mai A800S 4K Dash Cam to facilitate continuous loop recording of driving footage.
Handheld Gaming: Integrated into the storage port of the Analogue Pocket to allow users to load game ROMs and save states.

Q1. How can you ensure the quality?

A:  All our products are 100% tested before delivery. Durable quality is guaranteed.

Q2: How can we get the samples and best quotation?

A:We need to know more details about the products you inquired. 

    For example, what are the functions you need? The specification of it and which finished products will be used with it?

    It is better to provide AI fromat artwork to us so we could provide best quotation to you asap.

    We could provide the free samples to you. 

Q3: How long will the samples take to my place?
A: It depends on the express solution you choose, normally it will take 3-5 working days for the fastest way in hihgest price. And commonly in 5-8 days for the cost-effective way.

Q4. Can you open mold for teminal order or uncommon mold?
A: OK, we need time to discuss in details, such us the cost for open mold, and need to know the forecast, end product and lifespan.

Q5:What kind of files are required for quotation?
A: For PCB quotation, please provide the Gerber data / files and indication of related technical requirements as well as any special
    requirement.
    For PCBA quotation, please provide Gerber data / files and BOM (bill of materials). If you need function test, please also provide
    the test instruction/ procedure.
