HEIDENHAIN TS 440 Series

Workpiece touch probes with infra-red transmission

ts400 

The TS 440 and TS 444 are compact workpiece touch probes with infra-red transmission, designed for use in machining centres with automatic tool changing. The TS 444 is notable for its power source - it is powered by an integral air turbine.
