Shimpo Instruments DT-311J Data Sheet

DT-311J NEMA 4X Stroboscope for Harsh Wet
Work Areas

Where powerful illumination and rugged speed measuring accu­racy is required for the textile industry, the DT-311J will perform
where other stroboscopes will not. The DT-311J is used to set
injection timing, injection pressure, timing of shedding and weft
running time of weaving machinery. Units combine rugged NEMA
4X (IP65) housing with high performance accuracy, special phase
shifting, with shock absorbing components and top mounted
handle, allows the equipment operator maximum flexibility when
setting the timing of weaving machinery.
