DM3AT-SF-PEJM5 Introduction

The secure digital microSDTM surface mount applications’ 10 (8 + 2) position card connector, the DM3AT-SF-PEJM5, has a right-angle gold design. This connector belongs to a group of connectors that share characteristics in all of its forms. Let’s examine more closely the DM3AT-SF-salient PEJM5’s characteristics.

DM3AT-SF-PEJM5 Features

With a right-angle gold design, the DM3AT-SF-PEJM5 is a 10 (8 + 2) position card connector for secure digital microSDTM surface mount applications. This connector belongs to a group that shares characteristics with all its variants. Let’s examine the DM3AT-SF-salient PEJM5’s characteristics in detail.

  • The DM3AT-SF-incredibly PEJM5’s compact size is one of its most striking qualities. This connector is the smallest on the market thanks to its small external dimensions and above-the-board height. It is built of high-strength materials, which, despite its small size, create a strong and rigid structure, ensuring durability and dependability in any application.
  • The DM3AT-SF-innovative PEJM5’s reverse card insertion protection is another noteworthy aspect. When the card is attempted to be put in reverse, the special card slot design safeguards the connector from damage, allowing it to be reinserted correctly. With the help of this feature, the connector and card are always kept safe and secure.
  • The DM3AT-SF-efficient PEJM5’s ground and shield configuration is another crucial aspect. The metal cover’s four connecting points to the printed circuit board provide a reliable connection to the ground circuit and offer EMI protection. This function offers dependable performance and electromagnetic interference defense.
  • Moreover, the DM3AT-SF-PEJM5 has a card detection switch typically left open. By detecting the card’s presence or absence, this switch makes monitoring and regulating its usage simpler.
  • Part of a larger family of connectors, the DM3AT-SF-PEJM5 also includes the DM3BT, DM3CS (Push-Push with ejection mechanism), and DM3D. (Push-Pull, manual, without ejection mechanism). Each version in the series has distinct qualities and advantages of its own.
  • The push-push design of the DM3BT and DM3CS versions includes an ejection mechanism to stop unintentional card ejection or fallout. The solder termination joints may be easily inspected and repaired thanks to exposed termination leads.
  • With its hinge, push-pull, manual, no-ejection mechanism, the DM3CS variant enables quick and trustworthy card insertion. The card is guided during insertion and removal by the metal hinged cover. A tactile click is produced when the cover is closed to certify the mechanical and electrical connection. The distinctive contact design and card slide movement make a possible secure connection with the card contact pads.

Last but not least, the DM3D variant has a push-pull manual without an ejection mechanism that secures the partially inserted card. The card won’t slip out even when partially inserted, and a distinct tactile feel verifies complete insertion and electrical/mechanical connection. This design uses a reworkable inner lead system, and contact solder terminations can be examined and improved.

As a result, the DM3AT-SF-PEJM5 is a superb option for any secure digital microSDTM surface mount application because of its remarkable characteristics, like reverse card insertion prevention, an efficient ground and shield configuration, and a remarkably small footprint. Given its dependable performance and longevity, it is not surprising that the DM3AT-SF-PEJM5 is one of the most well-liked connectors on the market.

Detailed Description

For industrial applications that demand dependable and secure connectivity in constrained places, the DM3AT-SF-PEJM5 connector is appropriate. One of the tiniest and toughest connections on the market, it is made to accommodate the Secure Digital (microSDTM) format and has a small size, a right-angle design, and gold plating.

A special card slot design on the DM3AT-SF-PEJM5 guards against harm when the card is inserted backward. This function ensures that the card may be correctly reinserted and safeguards the connector and card from harm. The DM3AT-SF-PEJM5 connector is distinctive and dependable because it has patented reverse card insertion protection.

Detailed Features.

Features Common to The Entire Series

The DM3AT-SF-PEJM5 is one of a group of connectors that share a number of essential characteristics. These are a few of the common characteristics:
