TE Expands Mezalock Line of Connectors

Additions to the Mezalok line of connectors offer more design flexibility with new stack height and pin density options.

TE Mezalok Family 2014TE Connectivity has extended its rugged, high-speed Mezalok mezzanine connector family. The new extensions include a stack height of 15mm and a new 320-position size, which fill a height gap and add additional pin density. The Mezalok connector family has been designed specifically for mezzanine cards in rugged applications and is standardized as the interconnect for XMC 2.0 (VITA 61).

Rapidly evolving technologies in military electronics, such as signal intelligence, radar, communications, and surveillance, are driving the demand for higher data rates and increasing processing power in embedded computing solutions. Mezzanine cards are often used to provide additional functionality and processing capability within a small form factor. The Mezalok connector family was developed to support these applications. Typical applications include application-specific, high-speed, input/output (I/O) protocols, graphics, memory, and digital-signal processing.

“New designs in rugged embedded computing require higher speeds and high pin counts in order to pack more functionality into smaller plug-in modules,” said Mike Walmsley, product manager, Global Aerospace, Defense & Marine, TE Connectivity. “TE recognizes this trend and is continuing to build on this platform to help solve customer needs, offering new options in stack height and pin density, giving the system designer a broader solution set to work with when needing a fast, rugged, and reliable mezzanine connector for extreme environments.”

TE’s high-reliability mezzanine connectors more than double the speed and durability of competing technology, making it one of the most viable options for today’s military and commercial aerospace applications. At 5GHz+, this rugged, surface-mount mezzanine connector incorporates a redundant “mini-box” four-point contact system for separable interface and ultra reliability and offers excellent signal integrity up to 10Gb/s. LCP plastic housings offer superior thermal stability and are low-outgassing. In addition, compliant BGA board attach supports standard surface-mount processing and excellent thermal stability with a contact design that provides robust, uniform solder joints.

The TE Mezalok mezzanine connector family has been engineered for high-speed reliability, providing:

  • Reliable four-point box contact based on M55302, supporting 500 mating cycles
  • Protected socket end for reliable blind mateability
  • Optimal thermal stability, proven to 2,000 thermal shock cycles

For product configurations, TE offers:

  • 114-position Mezalok connectors compliant to VITA 61 (XMC 2.0)
  • 10, 12, 15, and 18mm stack heights
  • 60, 114, and 320 position sizes
