HEIDENHAIN's New Infrared Touch Probe Suitable for Mechanical Activation

SCHAUMBURG, IL - (July 2009) - The new TS 642 touch probe from HEIDENHAIN features mechanical probe activation and is suitable for both older HEIDENHAIN controls as well as current third party controls. This is especially useful in machines that are not set up to offer touch probes as standard options.

A key component in the TS 642 probe is a mechanical activation microswitch in the taper shank. This makes it useful for applications that do not permit infrared activation. This shank switch allows activation once the probe is inserted in its spindle. Once removed, the probe automatically shuts off thus optimizing probe battery life.

The new TS 642 also has flexible protocol capabilities allowing for easy interface to 3rd party controls in retrofit applications. With its integrated blower jets, the TS 642 makes it possible to clean the measuring point with coolant or compressed air.

The TS 642 can be operated for 800 hours of continuous duty with a set of lithium batteries. Alkaline or rechargeable batteries can also be used. The transmission range of the TS 642 is 7m, facilitating covering even large working spaces.

This probe's optical triggering also makes it an inherently reliable tool as no requirement for recalibration is ever necessary.
