INDUcoder LINEAR MOTION TRANSDUCER now with ETHERNET Powerlink The linear motion transducer of model range PLE, PLA, PCE and PCA are robust and compact position displacement measuring systems with measuring range up to 30,000 mm. This measuring system acquires a linear motion by unwinding a high flexible steel cable from a precision cable drum. Spring mechanics keep the stainless steel cable under permanent tension and enable the drum to wind up the cable on reversed moving direction. Due to especially strong springs high accelerations of cable up to 100 m/s² are permissible. This allows the application of this transducer in highly dynamical systems. By means of a spindle with adequate pitch according to the cable diameter, the cable drum is tracked so that the stainless steel cable is winded up in a single layer over the whole measuring length. Therefore a high linearity over the full measuring range is guaranteed. The incremental or absolute encoders with package diameter of 58 mm mounted to the cable drum convert the rotation into electrical signals and make the exact position data available. The following linear motion transducer with case height and measuring length are selectable by the customer:
The linear motion transducer can be operated with incremental shaft encoders as well as with absolute encoders. Using the incremental shaft encoder ED 58 / EE 58 resolutions up to 20 µm are achievable. The incremental signals are transmitted via RS422 line driver or push-pull outputs. Supply voltage is 5 VDC TTL or 10 - 30 VDC.
Using absolute encoders resolutions up to 24 µm are achievable.
The complex wiring reduces a lot when using encoders with field
bus interfaces. Also the more and more used field bus interface
ETHERNET Powerlink, with its well known advantages, is available
for the linear motion transducer with mounted ABSOLUTE ENCODER
