The SP550-S right angle TRS connector is
unlike anything of its kind! Currently the lowest profile soldered TRS
right angle connector on the market, the SP550-S features a thickness of
only 8.9mm (0.350"). The connector is the same width and height as its
counterpart (SP400) 17mm x 28mm.
The square connector allows it to be
plugged adjacent to other square plug connectors, unlike the common
"pancake" connectors within the industry.
The SP550-S connector fits cables with an O.D. of up to 5.8MM.
