Renishaw’s TONiC Dual Output encoder provides simultaneous digital and analogue signals

Renishaw's TONiC Dual Output (DOP) encoder interface, provides simultaneous digital quadrature and analogue 1 Vpp signals, via a 26-way D-type connector.

The interface is connected so that the analogue signals are wired to the motion controller, whilst the digital signals, with resolutions to 5 nm, are routed to the timing circuit of a synchronised operation, such as a camera flash on an inspection machine.

The total encoder system comprises a TONiC readhead, a DOP interface , and a variety of high performance linear and rotary scales.

TONiC incremental linear encoders are compatible with a range of scale options, including gold tape scale with integral optical reference marks, Invar spars with "zero" thermal expansion and ±1 µm accuracy on lengths up to 1130 mm, robust stainless steel spars and FASTRACK RTLC linear encoder scale system with ±5 µm/m accuracy.

RESM rotary encoder rings are available in a range of standard diameters from 52 mm to 550 mm and, when used with dual readheads, REXM rings have a total installed accuracy better than ±1 arc second on ring diameters greater than 100 mm.

Furthermore the product satisfies the environmental standards, with both WEEE and RoHS compliance.
