Performance
| Measurement range | 0 m … 1.25 m |
| Reproducibility | ? 0.2 mm 1) 2) |
| Linearity | ? ? 2 mm 1) 3) |
| Hysteresis | ? 0.4 mm 1) 4) |
| Resolution (wire draw + encoder) | 0.06 mm 5) 6) |
- 1) Value applies to wire draw mechanism.2) Reproducibility, repetition accuracy, or even repeatability is defined as the maximum scatter from consecutive positioning operations from a single direction to a point, carried out under identical conditions.3) The accuracy of wire draw encoders is primarily described by the linearity. This indicates the maximum deviation for the measurement of a defined measuring path. In contrast to repeatability, this relates to the measuring range covered and not to a positioning point.4) The hysteresis is defined as the maximum scatter from consecutive positioning operations from different directions to a point, carried out under identical conditions.5) The values shown have been rounded.6) Example calculation based on the PFG08 with HTL Push Pull: 230 mm (wire draw length per revolution – see Mechanical data): 16,384 (pulses per revolution) = 0.014 mm (resolution of wire draw + encoder combination).

- 1) These values were measred at an ambient temperature of 25 ?C. There may be variations at other temperatures.2) A cycle consists of the wire being pulled out and drawn in.3) The service life depends on the type of load. This is influenced by environmental conditions, the installation location, the measuring range in use, the traversing speed, and acceleration.
