- Encoder TONiC with scale RTLC in FASTRACK guides and with self-adhesive scale RTLC-S
TONiC encoders combine a low SDE (Sub-Divisional Error), which gives smoother speed control, with extremely low noise (jitter), which provides exceptional positioning stability and resolution up to 1 nm. Such impressive characteristics of this encoder allow to use it together with FASTRACK guides , which are characterized by high accuracy and small hysteresis.
As well as the FASTRACK guides, TONiC encoders provide a fast and easy installation. The resistance to unfavorable operating conditions and the reliability of operation over long periods of time are guaranteed by the optical filtering system and automatic gain control, which gives a high degree of immunity to dirt, scratches and greasy fingerprints - factors that can lead to errors in the reading of encoders from other manufacturers.
Ultra-compact reading head of linear encoder with high-precision scale tape RTLC
Renishaw´s TONiC series is a new generation of ultra-compact encoders that have been specially developed for precision linear motion measurement systems, the series encoders provide higher accuracy and speed, as well as increased reliability, and are used in a number of industries where very high demands are made to the measurements.
TONiC reading head is supplemented by a new scale RTLC tape installed in the FASTRACK guides, this tape has an accuracy of ± 5 μm/m and is equipped with optical zero marks IN-TRACTM with two-way repeatability located at intervals of 50 mm (or 200 mm for lengths exceeding 1 m). The user can select one or more labels by installing self-adhesive magnets.
An excellent level of accuracy control for linear movements
In order to achieve maximum reliability and a high degree of immunity to contamination, the TONiC reading heads are equipped with a third generation optical signal filtering system that provides an even lower noise level (jitter), the efficiency of this system is further enhanced by dynamic signal processing including automatic adjustment amplification and bias. As a result, a low subdivision error (SDE) is achieved, which provides smoother speed control, and this allows improved scan results and improved positioning stability. For the TONiC reading heads, a removable analog or digital interface is also available, implemented as a solid, convenient connector that can be located up to ten meters from the head.
This interface can perform digital interpolation with a resolution of up to 1 nm, with synchronized output signals to achieve optimal performance at any resolution in the case of standard controllers.
Dual interface
TONiC reading heads are also available with a so-called dual interface (DOP-dual output), which simultaneously provides digital and analog signals, which is very useful in the manufacture of photovoltaic cells and flat panel monitor equipment where analog signals can be used by the control system while synchronized digital signals can be sent to the camera synchronization circuit at this time.
