Compact workpiece touch probe with M12 connector


The TS 249 is a compact touch probe - the outside diameter is only 30mm - making it suitable for installation where space is limited. It features a variety of output signals making it suitable for integration with virtually any CNC system. The voltage free NO/NC contacts are compatible with the FANUC high speed skip input.

Axial or radial cable options offer flexibility in mounting.
