Two touch probes from Heidenhain employ what the company describes as hybrid technology, using both radio and infrared signal transmission. The probes are the TS 460 for workpiece measurement and the TT 460 for tool measurement. Dual signal transmission enables the user to select either mode, taking advantage of radio when extended range and large amounts of data are required, or infrared when high accuracy and fast signal transmission are needed. That way, one probe version can be operated on any machine size, the company says—from small and enclosed to large and open.
The radio transmission uses the 2.4 GHz frequency band, which does not require a license, and has 16 channels. The range is usually 15 m, but much larger ranges are possible under ideal circumstances. The infrared transmission has a range of 7 m. The carrier frequency method makes this transmission reliable, and the high frequency ensures a short delay time. No matter which signal transmission is chosen, users need only one SE 660 transmitter-receiver unit. Both probes have a 360-degree range of transmission.
The company says the compact design of these touch probes makes it possible to use them even where installation space is limited. The profile of the TS workpiece probe is designed for freedom when tilting the probe into position. This probe also has blower jets for cleaning the workpiece, either with coolant or compressed air. Probe power is supplied by size ½ AA batteries, which can be exchanged easily without tools.
