GI-D120 Series  0-10000mm Measurement Range Draw Wire Encoder Draw wire sensors are low-cost, compact sensors which accurately measure the position or change in position of objects. Core components of a draw wire sensor are a precision measuring wire and a sensor element (e.g. potentiometer or encoder), which convert the path change into a proportional electrical signal. The maintenance-free draw wires are particularly quick and easy to assemble and are used because of their reliability in all areas of industry. How does Draw Wire Sensor work? String pots or cable-extension transducers are composed of four main components inside the housing:
  1. Flex High Strength Stainless Steel Cable (string or wire rope);
  2. Constant Diameter Spool (drum);
  3. High Torque, Long-life Power Coil Spring;
  4. Rotational Potentiometric Precision Sensor.   
Inside the transducer's housing, a flexible high strength stainless steel cable is wound tightly around a precisely machined constant diameter cylindrical drum (or spool) that turns as the measuring cable reels and un-reels. To maintain wire tension and retraction, a spring is coupled to the drum. The spool is then coupled to the shaft of a rotational potentiometric precision sensor (or an encoder).  As the sensor string extends linearly along with the moving object, it causes the drum and sensor shafts to rotate. In order to take displacement or position measurements, the sensor’s body is mounted to a fixed surface and the end of the flexible cable is connected to the object in motion. As the object changes its positions, the cable un-reels and reels and the rotating spool drives the shaft of the sensing device generating an electrical signal that is proportional to the cable's linear extension or displacement. For speed measurement, a tachometer is required. The draw wire displacement sensor can be hooked up as a three-wire tapped potentiometer (voltage divider) or can be packaged with embed electronics to produce an output signal in a useful form, such as a variable voltage 0-10 VDC, variable current 4-20mA, pulse encoder, Fieldbus (Profibus, DeviceNet, and Canbus) and RS232 / RS-485 communications. The sensor output signal can then be sent to a signal conditioner for amplification, local display or readout, a PLC or data acquisition system (DAQ).  GI-D120 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.

Packaging Details The rotary encoder is packed in standard export packaging or as required by buyers;   FAQ: 1) How to select an encoder? Before ordering encoders, you could clearly know which type of encoder you may need. There are incremental encoder and absolute encoder, after this, our sale-service department would better work for you. 2) What specifications are requested before order an encoder? Encoder type----------------solid shaft or hollow shaft encoder External Diameter----------Min 25mm, MAX 100mm Shaft Diameter---------------Min shaft 4mm, Max shaft 45mm Phase & Resolution---------Min 20ppr, MAX 65536ppr Circuit Output Mode-------you could choose NPN,PNP,Voltage, Push-pull,Line driver, etc Power Supply Voltage------DC5V-30V 3) How to choose a right encoder by yourself ? Exact Specification Description Check The Installation Dimensions Contact Supplier to get more details 4) How many pieces to start ?  The MOQ is 20pcs .Less quantity is also ok but the freight  is  higher. 5) Why choose "Gertech" Brand Encoder?
