Stac64 Single, Multi-Pocket and Hybrid Header System

Molex introduces a stackable connection system that provides single- and multi-pocket PCB solutions, offers a diverse range of circuit sizes, and greatly reduces time-to-market

Molex's Stac64To address the growing electronic device requirements within today's vehicles, Molex has developed a modular 0.64, 1.50, and 2.80 mm terminal-header system. The Stac64 connection system allows OEM and device manufacturers greater design flexibility to support both low-level signal requirements, as well as power applications up to 30.0 A. The Stac64 system allows automotive manufacturers to use header assemblies as stand-alone components, as well as gang multiple headers together to support a large range of signal and power needs for devices and modules.

The standard product line based on the 0.64 mm pitch terminal includes 8-, 12-, 16-, and 20-circuit connectors in both vertical and right-angle headers, supporting low-level signal requirements. In addition, 10- and 14-circuit power-pocket versions, supporting power applications for 1.50 and 2.80 mm pitch terminal systems, are available in vertical and right-angle configurations. This Stac64 is a standard product system based on USCAR-2 Class II mechanical- and electrical-performance characteristics for unsealed connector applications. The connectors mate to existing wire-harness connectors designed to the USCAR/EWCAP industry footprints.

The Stac64 standard-product offering is tooled at high-cavitation and is fully validated at the single-pocket level. This greatly reduces time-to-market by eliminating the need for additional tooling. Bio-plastic Stac64-e, the automotive industry’s first renewable, plant-based resin connector, provides an alternative to traditional petroleum-based connectors while offering equivalent performance and quality characteristics of the proven Stac64 connection system. Bio-plastic resin connectors address increasing demands for environmentally-preferable solutions for automotive applications. The Stac64-e connection system has received UL Environment ECV certification for containing 71% bio-based organic-carbon content.
