MSD-1-A Push-Push MicroSD (TF) Card Socket Connector (SINK / SMD / MR01A-01211)

Integrate reliable, user-friendly external flash memory expansion into your custom electronic designs with the MSD-1-A (part number MR01A-01211) surface-mount MicroSD (TF) card socket. Featuring a smooth Push-Push (Push-In / Push-Out) mechanical eject mechanism, this socket provides a spring-loaded tactile experience that allows users to easily insert and lock a MicroSD card into place, and push again to pop it out effortlessly.

Designed with a low-profile SINK (in-board / recessed) surface-mount footprint, it features robust metal shell grounding tabs alongside integrated card-detection switch contacts. The shielded stainless steel housing protects internal gold-plated signal pins against mechanical deformation, dust, and electromagnetic interference (EMI). It is an ideal component for IoT data loggers, custom Raspberry Pi / ESP32 expansion boards, audio players, flight controllers, and handheld portable electronics requiring removable storage.

Key Features:

• Push-Push Eject Mechanism: Tactile spring-loaded push-in/push-out retention ensures positive card latching and smooth extraction.

• Integrated Card Detect Switch: Dedicated internal switch pin allows microcontrollers (e.g., ESP32, STM32) to detect card insertion/removal in real time.

• Shielded Metal Housing: Stainless steel shell provides structural rigidity, EMI shielding, and robust grounding to the PCB.

• High-Reliability Gold Contacts: Prevents contact oxidation and ensures high-speed SPI / SDIO data transmission stability.
