Molex Stac64 Unsealed 'STACable' Connection Systems

Stackable connection system provides single and multi-pocket PCB solutions, offering a diverse range of circuit sizes and greatly reduces time-to-market by completely eliminating custom tooling

To address the growing electronic device requirements within today's vehicles, Molex has developed a modular 0.64, 1.50 and 2.80mm (.025, .059 and .110") terminal header system.

Molex Stac64 Connectors

The Stac64 connection system allows OEM and device manufacturers greater design flexibility to support both low-level signal requirements as well as power applications upwards of 30.0A. The system allows automotive manufacturers to use header assemblies as stand-alone components, to 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 0.64mm (.025") pitch terminal includes: 8-, 12-, 16- and 20-circuit connectors in both vertical and right-angle headers supporting low-level signal requirements. An additional 10-circuit 'power pocket' version, supporting power applications for 1.50 and 2.80mm (.059 and .110") pitch terminal systems, is 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 currently tooled at high cavitation and is fully validated at the single-pocket level. This greatly reduces time-to-market by completely eliminating the need for additional tooling.

Features and Benefits
Stackable connection system of readily available PCB headers Reduced time-to-market: engineering and validation times reduced significantly. No tooling necessary to produce custom multi-bay headers
The 20-circuit-header housings are molded in standard USCAR color schemes for additional polarizations Matches harness connector color coding scheme for visual aid in assembly
Pre-assembled, linear Mylar PC tail alignment strip for right angle headers Reduces PCB packaging complexity. Provides space savings
Modular-housing design with standard dovetail features molded into the housings Allows headers to be ganged together in large assemblies to meet growing terminal quantity requirements
PCB alignment posts Ensure all terminals are properly aligned into PCB board through-holes during assembly. Retain header to PCB during assembly and solder processing
PCB standoffs molded into housings Provide additional trace-routing real estate underneath the headers
High temperature thermoplastic housing Withstand infra red (IR) and wave lead-free solder processing per SMES-152 Molex specification
Pre-assembled TPA to receptacle housing shipped as single assembly Applied labor and cost savings
