New Canon LDV SensorsAid Production ControlCanon U.S.A. Inc. Semiconductor Division, Encoder Products, Lake Success, N.Y., reports its two new LDV sensors P-50Z and P-20Z provide precision control of product runs, and help reduce costs and waste in textile manufacturing. The compact sensors have a dual convergent semiconductor laser that can measure all types of fabrics during manufacturing, sizing and cutting. They provide accurate measurement of the velocity of running textiles without directly contacting the fabrics.The sensors can be used with both high- and low-density fabrics with reflectivity factors as low as 20 percent. The P-50Z is designed for use with large runs or faster run rates. The P-20Z is appropriate for measuring delicate or sensitive fabrics manufactured at slower speeds.December 2002
