The ST-329 is a permanent mount stroboscope array utilizing
super bright CREE high powered LED lamps. The ST-329’s LED
array provides a bright, stable strobe light over a wide measure-
ment range with a lifetime far exceeding xenon lit stroboscopes.
The ST-329 arrays are available in several standard sizes from
9.25” (235 mm) to 65” (1650 mm) in length. Custom sizes are
available upon request. The arrays are easily mountable on pro-
duction equipment. An optional mounting adapter kit is available
to aid in array installation. A separate control enclosure is con-
nected with 6.5’ (2 m) cable to the array. Operation is simple with
the 8 button keypad and large, backlit LCD display. Phase shift,
flash duration, plus flash rate are all quickly adjustable via the con-
trol. The unit can work off user programmed flash frequency or
from a remote sensor’s signal which will automatically adjust to
corresponding process fluctuations.
The ST-329 is designed for speed and frequency measurements
in the printing, packaging, textile, automotive, cable, mining, steel,
chemical, optical, medical and shipbuilding industries in various
applications.

Use in flammable environments is prohibited. Use in this manner may
result in fire or explosive.
Don’t look directly into the LED light Source. This may result in eye in-
jury.
