TONiC™ special solutions

The TONiC absolute encoder range includes a 'variety' of special products for both rotary and linear axes, which are designed to match the demands of particular applications, including the products shown below.

In addition, Renishaw can also provide a number of customer-specific modifications to meet your needs. If the standard TONiC product range (or our other encoders) doesn't exactly meet your requirements, please contact your local representative to discuss custom options.

1 nm resolution and ultra-low positional noise

TONiC ultra-compact linear encoder range now has 1 nm and 2 nm resolution versions. Available in linear encoder and rotary encoder formats, the new higher resolution options comprise a standard TONiC readhead and new Ti20KD (1 nm) or Ti10KD (2 nm) interfaces that apply high interpolation rates to achieve very fine resolution.

• Low jitter at just 0.51 nm RMS
• Enhanced positional stability
• Low-speed velocity control
• Easy set up, greater ruggedness and superior dirt immunity

TONiC Dual Output (DOP) interface

Designed for applications requiring one or more operations to be synchronised with a motion axis, Renishaw’s TONiC Dual Output (DOP) encoder interface provides simultaneous digital quadrature and analogue 1 Vpp signals via a 26-way D-type connector. Typically, the interface is connected so that the analogue signals are wired to the motion controller, whilst the digital signals (with resolutions to 1 nm) are routed to the timing circuit of a synchronised operation, such as a camera flash on an inspection machine.

• Simplifies wiring
• High-speed interpolation with advanced CORDIC algorithms boost performance
• Detachable DOP interface with integral interpolation to 1 nm resolution (0.00075 arc seconds for rotary versions)
• Digital outputs are clocked for optimised speed performance at all resolutions for industry-standard controllers
• Robust DOP interface can be situated up to 10 m from the TONiC readhead
