Linear encoders
Absolute
Our exposed linear encoders consist of a scanning head and a scale tape. These measuring systems are basically characterized by the following main features:
- The users slide system takes over the steering between the scanning head and the scale tape
- Non-contact optical scanning of the scale tape by the scanning head, thereby no mechanical retroactive effect on the slide system
- Low space requirement due to small dimensions of the encoder
- Individual measuring lengths of the scale tapes available (up to 1,200 mm)
- Several interfaces usable (digital and analog)
- Possibility of an electronic signal adjustment after mounting to reduce static mounting errors
- Two absolute tracks and two incremental sensors ensure high contamination immunity
- Wide range of supply voltages to compensate conduction losses
- Extensive diagnostic and monitoring functions (e.g. read head temperature)
- High control dynamics due to low calculation time
- Kit versions with customized frames and housings available (on request)
