SD Card Connector Types Explained: Push‑Push, Push‑Pull, Hinged, and More
What is an SD Card Connector?
An SD card connector is a precision-engineered component that enables secure electrical and mechanical connections between a host device and an SD memory card. These connectors are widely used in applications like smartphones, industrial sensors, automotive infotainment systems, and embedded electronics.
At Moarconn, we specialize in producing high-precision SD card connectors with proven durability, customizable features, and fast delivery from our in-house manufacturing plant.
Understanding the Insertion/Removal Mechanisms
Let’s break down the most common SD card connector types, each designed with a specific use case and user experience in mind.
1. Push-Push Connector
Mechanism:
Insert the card with a single push.
Push again to release (spring-ejection system).
Advantages:
Smooth user experience
No need for external tools
Ideal for consumer electronics and handheld devices
Applications:
Cameras, drones, IoT devices, automotive dashboards
2. Push-Pull Connector
Mechanism:
Card is manually inserted and pulled out.
No spring-loaded mechanism.
Advantages:
Simplified structure, cost-efficient
Fewer mechanical moving parts
Compact design
Applications:
Embedded systems, home appliances, low-maintenance designs
3. Hinged (Flip-Type) Connector
Mechanism:
Card is inserted under a hinged cover.
Cover snaps shut to secure the card.
Advantages:
High vibration resistance
Secure locking for harsh environments
Reliable mechanical retention
Applications:
Automotive systems, industrial controls, smart metering
Moarconn Application Case:
Our hinged SD connectors are commonly used in automotive infotainment systems requiring anti-vibration performance and elevated contact force stability.
How to Choose the Right SD Card Connector
When selecting an SD card connector, consider these factors:
Criteria
Insertion Cycles
Mounting Type
Contact Material
Environmental Needs
Size Constraints
Considerations
>5,000 for general use, >10,000 for industrial
SMT, through-hole, reverse mount, vertical
Tin, Gold-plated (for corrosion or signal integrity)
Heat, vibration, humidity resistance
Choose low-profile types for compact assemblies
