QMS-026-02-H-D

The QMS-026-02-H-D is an edge type mezzanine connector, a rectangular array. It is used for PCB connection, featuring a floating designed contacts. This connector supports signal, power, and coaxial transmission.

The QMS-026-02-H-D is commonly used in applications that require a high number of connections with high speed transmission rate, such as aerospace, medical, networking, automation, instrumentation, and robotic fields. Its design enables to support a very wide range of applications that require a high number of contacts.

The QMS-026-02-H-D consists of two components: an upper board and a lower board. The upper board is a rectangular array of terminal pins, while the lower board hosts the contact header. Each header contains sixteen contacts suitable for signal, power, and coaxial transmission. Both the upper and lower boards are fixed to the corresponding circuitry board.

The terminal pins on the upper board have a floating design which enable more mechanical stability as they are not fixed to the PCB, so this design accommodates for regular PCB and board warpage. The contact header is also fixed to the PCB and has an insulation displacement contact (IDC) connection. This connection allows multiple signal wires to be connected without using manual soldering.

The signal transmission speed of the QMS-026-02-H-D is up to 2 GHz, higher than most other PCB connectors, enabling high speed data transmission and signal integrity. The contact header is also available in various numbers, sizes, and types, depending on the application. The array is also designed to achieve an optimal spacing between the contacts, to make sure that the asperities between the terminals do not affect the transmission speed.

The QMS-026-02-H-D mezzanine connector can also be customised depending on the application requirements. Options for the adjustments include insertion force, contact force, contact resistance, keying configurations, and contact layout. This makes the connector suitable for multiple applications.

To sum up, the QMS-026-02-H-D is an edge-type mezzanine connector suitable for PCB connection. Its floating design terminal pins and high speed transmission make it a suitable choice for fields that require high speed data transmission such as networking, automation, aerospace, medical, instrumentation, and robotics fields.
