Delta SSMC connectors are microminiature, 50Ī© impedance connectors with 6-40 threaded coupling. SSMC connectors are ideal
for use in limited-space applications that require the rugged design of a threaded coupling interface. They are best suited for use
with semi-rigid cables or miniature
cables in demanding applications up to 12.4 GHz. Our extensive line of receptacles
contains a variety of mounting
urations and contact / insulator terminations perfect for any packaging requirements. Our
adapters are available in both in-series and between series. We also o
an adapter with a slide-on version of the SSMC inter
face
(See page 11) that is ideal for testing components; reducing wear and tear on mounted connectors and saving time on mating
and unmating of test cables.
Delta's SSMC connectors are designed in accordance with IEC 169-20, and are intermateable with other manufacturersā€™ SSMC
connectors. However, through our unique internal construction design, pr
ecision machining capabilities, and Lean Manuf
acturing
processes, we are able to
the highest quality components while optimizing both cost and lead time.
These connectors are machined to exacting tolerances and the highest quality standards on modern CNC turning centers, and
assembly is tightly controlled and monitored to ensure peak consistency of performance from unit to unit.
