- 1) The data shown is a mean value. The exact length is indicated on the label on the wire draw mechanism.2) These values were measred at an ambient temperature of 25 ?C. There may be variations at other temperatures.3) A cycle consists of the wire being pulled out and drawn in.4) 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.5) The built-on DFS60 encoders are programmed to the specified number of lines and interface prior to delivery. The electrical interface (TTL/HTL) and the number of lines (up to max. 10,000 lines) can be set in accordance with customer requirements with our programming devices for DFS60 encoders, which are available separately.
