MOLEX 46557-2345

1.27mm (.050”) Pitch
SEARAY*Slim 4-Row Connectors
FEATURES AND SPECIFICATIONS
SEARAY Slim offers a deceivingly narrow profile while providing a robust solution capable
of speeds in excess of 12.5Gbps.
SEARAY Slim is a solution armed with the benefits of
the standard SEARAY family but with a width similar to
2-row mezzanine products. The design meets system
needs as a highly compact solution but with speed
capabilities of 12.5 Gbps, a level of performance most
other 2-row products cannot achieve today. As systemlevel speeds approach 5Gbps and beyond, SEARAY
stands as an enticing mezzanine architecture that
provides headroom for future-generation iterations as
protocol speeds continue to increase.
SEARAY Slim pushes the envelope of the SEARAY
product family, offering a 4-row solution that is a
narrower version of the existing SEARAY housings.
Because Slim features Molex’s patented solder-charge
technology and can pack tighter signal density into
a 1.27mm (.050”) pitch, the connector width is
equivalent to that of standard 2-row SMT products.
With a flexible tooling strategy, SEARAY Slim can
offer circuit sizes ranging from 40 to 200 circuits and
stacking heights of 7 to 15mm (.236 to .591”).
SEARAY Slim’s slender profile provides design
engineers with a solution complementary to system
airflow and with a long body that provides ease in
routing signals through minimal signal layers, as few
as 2 layers if signals are routed to both sides of the
connector or 4 layers if all signals route to one side of
the mezzanine solution. In addition, unlike competitors
products available today, SEARAY Slim offers guide
posts for blind-mating capabilities.

Features and Benefits
■ Narrow body width comparable to 2-row SMT
products provides minimal PCB footprint for
high-density board designs and effective design
for airflow considerations
■ Data rates of up to 12.5 Gbps provide excellent
signal clarity and large bandwidth for customer
requirements in high-speed designs
■ Robust contact design prevents stubbing and
damage in mating interface
■ Molex’s unique and patented, solder-charge
technology are more cost effective and more
reliable than Ball Grid Array (BGA) attach methods
with less assembly processing required and a more
reliable PCB adhesion
■ Flexible tooling design with multiple stack heights
and circuit sizes provides ease in tooling a new
circuit size or stack-height version
