Surface Mount Push-Push Memory Card Connector

Dragino LG01 TF Card Connector's Product Introduction

KKG Electronics presents the TF-2532, a high-precision storage interface designed for modern electronic assemblies. This component utilizes a smooth "push-push" mechanism, ensuring the media is securely locked during operation and easily ejected with a soft press. While often utilized in devices that also require a dual sim connector for connectivity, this specific unit is dedicated to high-speed TransFlash storage expansion. The housing is constructed from high-temperature thermoplastics suitable for SMT reflow soldering processes. As a versatile card socket, it features a reinforced metal shell that provides excellent EMI shielding. Designers frequently pair this component with a sim socket on the same PCB to offer users both communication and memory capabilities. Its robust contact design ensures long-term reliability, making it a dependable sim connector alternative for storage-focused applications in consumer electronics and IoT gateways.

Samsung Galaxy A54 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.

Lenovo Tab P11 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.
System Integration: Often implemented alongside a dual sim connector to provide a complete communication and storage solution within a compact device footprint.
EMI Shielding: The stainless steel cover provides structural reinforcement and connects to the PCB ground pads to shield high-speed data signals from interference.

Smartphones: Integrated into the mainboard of the Samsung Galaxy A54 to provide expandable storage for photos and applications near the sim connector.
IoT Gateways: Used on the expansion slot of the Dragino LG01 LoRa Gateway to store local logs and sensor data configuration files.
Dash Cams: Located on the side of the Garmin Dash Cam Mini 2 to facilitate continuous loop recording of driving footage via the card socket.
Tablet Computers: Integrated into the chassis of the Lenovo Tab P11 to allow users to upgrade memory capacity easily.

Q1: Are you a direct manufacturer or a trading company?

A: KKG Electronics is a direct manufacturer with over 15 years of specialized expertise. We design and produce high-quality electronic components, including tact switches, micro switches, USB connectors, audio jacks, and more, directly from our own factory.

Q2: How can I request a sample or get a price quotation?

A: For an accurate quotation and the right samples, please provide us with details about your project. Key information includes technical specifications, intended application, and required functions. For the fastest service, providing artwork or a drawing (AI format is ideal) is highly recommended. We are happy to offer free samples for your evaluation.

Q3: How do you guarantee product quality and reliability?

A: Quality is our highest priority. Every component we manufacture undergoes a rigorous 100% electrical and mechanical testing process before shipment. This ensures that all our products meet the highest standards for performance, durability, and reliability.

Q4: What files are required for a PCB or PCBA quotation?

A: To provide an accurate quote, please supply the following:

For PCB Quotation: Gerber data/files along with any related technical requirements or special instructions.

For PCBA Quotation: Gerber data/files, a detailed Bill of Materials (BOM), and any testing procedures if functional testing is required.

Q5: How are the electronic components packaged for shipping?

A: We ensure our products are protected during transit. Components are packaged securely in anti-static bags or tape-and-reel formats, then cushioned with air bubble film inside a sturdy inner box and a durable outer shipping carton.
