Renishaw, world-wide specialist in technology of measurement and encóder, has developed the versions of 1 and 2 nm of his successful range of encóderes incremental TONiC. Available in formats of encóder rotary presses and linear, the new options of higher resolution include a new head reader TONiC and the new interfaces You20KD (1 nm) or You10KD (2 nm) that apply taxles of high interpolation to obtain a very precise resolution. Besides, the optical program of low interference of TONiC, with upper photometry, has been combined with the filtered internal advanced of the interfaces You20KD / You10KD to reduce the fluctuations (interferences in the position notified) until an impressesive under level of only 0,51 nm RMS.

The low fluctuations and the resolution increased provide an encóder with a stability of position considerably improved and a control of low speed. The improvement is complementary to the advantages of the condicionamiento of dynamic signal, included of series in all the cabezales of reading TONiC.

Therefore, the encóderes incremental TONiC of 1 and 2 nm provide all the advantages of an encóder of 20 micras of step, like ease of configuration, more resistance and an immunity to the upper dust, still like this, can compete with resolutions and levels of interference of other systems of encóder of the competition of step much more precise

The version of encóder linear of TONiC is available with a wide range of options of rule. RGSZ Is the last development of the omnipresente rule of flexible strip chapada in gold of Renishaw, now with marks of optical reference IN-TRAC integrated. The rules RELA of Invar —commercial mark registered of Arcelor Mittal— offer an expansion ‘zero' and a precision of +/-1 µm in lengths until 1.130 mm. To obtain a high performance in long axes and a significantly greater robustness that the rules of glass, the rules of stainless steel have a precision of +/- 4 µm in 5 m. Besides, for a faster installation and easy, the new system of rule of encóder linear Fastrack delivers with a rule of low profile RTLC with a precision of +/-5 µm/m.

The options of encóder (angular) rotary with rings RESM, supply in a range of diameters between 52 and 550 mm, with diameters even greater available optionally. To obtain a still greater performance, the encóderes of ring REXM of precision ultra high have of an installed total precision upper to +/-1 arcosegundo in diameters of ring of more than 100 mm, used in cabezales of double reading.

The interfaces have designated according to his factors of interpolation: You20KD corresponds to a digital interpolation of 20k (post-quadrature), that equivale to 1 nm of resolution.

Like all the encóderes of Renishaw, the encóderes incremental TONiC are backed by a network of sales and international technical service that answers truly to his needs. Besides, the product satisfies the environmental requirements more demanding, fulfilling the Directive of Waste of Electrical and Electronic Devices (WEEE, of the English Waste Electrical and Electronic Equipment) and the directive 2002/95/CE of Restriction of Dangerous Substances in electrical and electronic devices, (RoHS, of the English Restriction of Hazardous Substances).
