Draw Wire Sensor Operating Principle
Draw wire sensors are small in size compared to their measuring range. Often a draw wire sensor would be selected for an application if space were limited or if the measuring range was very large. Draw wire sensors consist of a flexible measuring cable, a spool, a spring and a rotational sensor (typically a potentiometer). The measuring cable is precisely wound around the spool; the rotational sensor is also attached to the spool. One end of the cable is attached to the object requiring measurement. As the cable is pulled it unravels from the spool which turns the rotational sensor allowing it to accurately measure the distance the object has moved based on the number of rotations it has taken. The spring is required to maintain tension within the mechanism. GI-D80 Series encoder is a 0-4000mm 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.D80 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.

Five steps let you know how to select your encoder: 1.If you've already used encoders with other brands, plz feel free to send us the information of the brand info and encoder info, like model no, etc, our engineer will advise you with our euqivalent replacement at a high cost performance; 2.If you want to find an encoder for your application, plz first select encoder type: 1) Incremental encoder 2) Absolute encoder 3) Draw Wire Sensors 4) Manual Pluse Generator 3. Choose your output format(NPN/PNP/LINE DRIVER/PUSH PULL for incremental encoder) or interfaces(Parallel, SSI, BISS, Modbus, CANopen, Profibus, DeviceNET, Profinet, EtherCAT, Power Link, Modbus TCP); 4. Select the resolution of the encoder, Max.50000ppr for Gertech incremental encoder, Max.29bits for Gertech Absolute Encoder; 5. Select the housing Dia and shaft dia. of the encoder; Gertech is popular equivalent replacement for similar foreign products such as Sick/Heidenhain/Nemicon/Autonics/ Koyo/Omron/Baumer /Tamagawa/Hengstler /Trelectronic/Pepperl+Fuchs/Elco/Kuebler ,ETC.
