GI-D315 Series  0-10000mm Measurement Range Draw Wire Encoder

Draw wire sensors comprise a precision drum, wound with stainless steel cable and mounted to a rotary sensor.  The sensor is usually an encoder or a potentiometer, depending on the performance required.  As wire is pulled off the spring-loaded drum, it rotates the sensor creating a signal that is proportional to the length of wire extracted. This technique makes for a versatile linear sensor package.

Draw wire sensors offer a simple solution to measure linear speed and position. Utilizing a flexible cable, a spring-loaded spool, and a sensor (an optical encoder with incremental, absolute, analog or potentiometric output), draw wire sensors can precisely measure linear position. These sensors do not need precise linear guidance and are ideal for wet, dirty, or outdoor environments and applications where your measuring range travels through a harsh environment or hard-to-reach places. These include applications in iron, steel, sawmills and joineries.

Draw wire sensors are also known in the industry as cable transducers, cable-extension transducers, string potentiometers (“string pots”), draw wire transducers, yo-yo pots, linear position string pots, and string encoders.

GI-D315 Series encoder is a 0-10000mm measurement range high accuracy draw wire sensor. It provides optinal outputs: Analog-0-10v, 4 20mA;  Incremental: NPN/PNP open collector, Push pull, Line Driver; Absolute:Biss, SSI, Modbus, CANopen, Profibus-DP, Profinet, EtherCAT, Parallel etc. Wire Rope Dia.:0.6mm, Linear Tolerance:±0.1%,The aluminum housing provides a reliable sensor ideal for industrial environments. Being both economical and compact, these are appropriate for a wide variety of applications.D315 Series provide extremely precise measurements because of the inherent accuracy of the encoders(both absolute and incremental encoders) and the rugged construction ensures reliable performance even under extreme conditions. Measurements are highly accurate, reliable and the systems have very long lifetimes without losing its inherent characteristics.
