LED stroboscope Array
The Series ST-329 is apermanent mount LED stroboscope arrays utilizing super bright CREE, high powered LED lamps. The ST-329 emits standard light for typical high speed applications. The ST-329 LED array provides a bright, stable strobe light over a wide measurement 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 production equipment. An optional mounting adapter kit is available to aid in array installation. A separate control enclosure is connected 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 controller. 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.
  • Wide Flash Range 60 - 120,000 Flashes/min. can be adjusted to meet almost any high-speed application
  • Long-life LED operation
  • Adjustable Flash Pulse duration achieves sharper images for detailed inspection
  • Phase Shift Advances or retards flash timing for viewing gear teeth, cutting surfaces, repeats or "drifting" images
  • Input sensor trigger function allows process machinery to control flash rate
  • Delay time adjustment combined with leading or trailing edge activation simplifies process set-up when using external signal input
  • Ten standard size lengths from 9" (235 mm) to 65" (1650 mm). Custom options available
  • x2 and 1/2 keys for large adjustment rate change or +/- for fine tuning
