Product Features

• Push‑push latching ejection: one‑hand operation; push‑in lock, push‑again spring eject; prevents accidental card drop‑out under vibration
• 9‑pin contacts, 1.10 mm pitch, integrated card‑detect switch (NO signal output)
• External‑welding SUS304 stainless‑steel shell, multiple ground solder points for stable EMI shielding
• SMT surface‑mount termination with PCB retention claws, anti‑floating during reflow soldering
• High‑temperature UL94V‑0 LCP housing, compatible with standard SMT reflow profile
• Phosphor‑bronze contacts with gold‑nickel plating; PCB terminals tin‑plated for good solderability
• Support microSD, microSDHC, microSDXC UHS‑I memory cards
• Embossed tape‑and‑reel packing for automated SMT assembly lines

Product Advantages

1. Footprint compatibility: Pin‑to‑pin compatible with Hirose DM3 series, reuse original PCB land pattern, no PCB redesign, shorten project validation cycle.
2. External‑weld SUS shell: Multiple ground solder pads strengthen EMI shielding effect; better anti‑interference performance compared with internal‑weld shell versions, ideal for noisy industrial circuits.
3. Push‑push anti‑drop‑out latch: Stable mechanical locking under vibration & shock, avoid accidental card ejection for field‑deployed devices.
4. Built‑in card‑detect switch: Hardware‑level card‑insert signal for MCU detection; no extra external circuit required.
5. Mass‑production friendly: Retention claws prevent component floating during reflow; reel packing fit high‑speed SMT assembly.
6. Wide environmental adaptability: Industrial‑grade temperature range‑40~+85 ℃, stable performance for outdoor, portable and embedded hardware.
