SIM, SD & Micro SD Card Socket Connectors

M&T provides different Card Socket Connectors according to card format, installation space, PCB layout, insertion mechanism, and application requirements.

SIM Card Connectors

Our SIM Card Connectors include Nano SIM, Micro SIM, and other SIM socket configurations designed for stable contact between SIM cards and electronic devices. Different contact layouts, socket heights, and insertion structures are available for compact electronic designs.

SD & Micro SD Card Connectors

M&T supplies SD Card Connectors and Micro SD Card Connectors, including compact TF card sockets for removable data storage applications. Low-profile structures help engineers integrate memory card interfaces into space-constrained PCB designs.

Depending on the model, card sockets are available with push-push, push-pull, self-ejecting, and other insertion/ejection structures to suit different device designs and user interaction requirements.

Card Socket Connector Selection for PCB Design

Selecting a suitable card connector requires more than matching the card format. PCB designers and purchasing teams should also consider connector height, mounting footprint, insertion direction, contact configuration, operating environment, and expected insertion cycles.

Key selection factors include:

• Card type: SD, Micro SD/TF, Nano SIM or Micro SIM

• Connector height and PCB footprint

• Pin and contact configuration

• SMT or other mounting requirements

• Push-push, push-pull or self-ejecting structure

• Contact resistance and insulation performance

• Rated current and voltage

• Operating temperature

• Required insertion and removal durability

M&T provides detailed specifications for individual models to help engineering teams compare card socket options before sampling or production.

Custom Card Socket Connectors for OEM Projects

For projects where a standard connector does not match the PCB or enclosure design, M&T can support Custom Card Socket Connectors based on drawings, samples, dimensional requirements, or application specifications.

Customization can involve connector dimensions, contact arrangement, housing structure, mounting configuration, terminal design, card insertion mechanism, and other mechanical or electrical requirements.

M&T integrates mold design and processing, product development, production, and automated manufacturing capabilities, allowing us to support customers from connector evaluation and sample development through volume production.

FAQ

What types of card socket connectors does M&T manufacture?

M&T supplies SD, Micro SD/TF, Nano SIM, Micro SIM, SIM/SD combination, and other card socket connector configurations for electronic and embedded device applications.

What is the difference between an SD card connector and a Micro SD card connector?

They are designed for different memory card formats and therefore differ in dimensions, PCB footprint, contact arrangement, and mechanical structure. Micro SD connectors are typically selected when PCB and enclosure space is limited.

What card insertion mechanisms are available?

Depending on the model, M&T offers push-push, push-pull, self-ejecting, and other card insertion structures. The appropriate mechanism depends on device space, user access, PCB design, and application requirements.

Can M&T customize a card socket connector for my PCB?

Yes. M&T supports connector customization based on customer drawings, samples, PCB requirements, dimensions, and application specifications. Contact our team with your technical requirements for evaluation.

What information should I provide when requesting a card socket connector?

Providing the card type, connector dimensions, mounting method, insertion mechanism, pin configuration, electrical requirements, drawing or sample, application, and estimated purchasing quantity will help us recommend a suitable model more efficiently.
