L957970B TONiC encoder system Renishaw s TONiC series represents a new generation of supercompact encoders, designed for highlydynamic precision motion systems, bringing higher accuracy, speed and greater reliability to a wide variety of demanding industry sectors. The readhead is complemented by the latest evolution of RGSZ20 gold tape scale, REXM ultrahigh accuracy angle encoder and FASTRACK /RTLC scale system with bidirectional optical INTRAC reference marks, in addition to established RSLM stainless steel scale, RELM high accuracy low expansion, high stability scale and RESM rotary rings. For ultimate reliability and high dirt immunity, TONiC readheads incorporate thirdgeneration filtering optics, tuned for even lower noise (jitter), further enhanced by dynamic signal processing including Auto Gain Control and Auto Offset Control. The result is low subdivisional error (SDE) giving smoother velocity control for improved scanning performance and increased positional stability. TONiC readheads also feature a detachable analogue or digital interface in the form of a robust, convenient connector that can be located up to m from the readhead. The interface offers digital interpolation to nm resolution, with clocked outputs for optimised speed performance at all resolutions for industrystandard controllers. Compact readhead (5 x.5 x mm) Compatible with RGSZ20 gold tape scale, FASTRACK/RTLC scale system, RSLM, RELM, RESM, RESD and REXM with customerselectable INTRAC autophase optical reference mark (datum) Thirdgeneration filtering optics optimised for even lower noise (jitter) Dynamic signal processing provides ultralow cyclic error of typically ±0 nm Auto Gain Control ensures consistent signal strength for longterm reliability Increased ride height tolerance and integral setup LED for ease of installation Maximum speed to m/s (.2 m/s at 0. µm resolution) Detachable analogue or digital connector with integral interpolation to nm resolution (0.00075 arc seconds) Integral dual limits (linear only) Operating temperature to 70 C Dual resolution version available

The inner shield should be connected to at receiving electronics only. Care should be taken to ensure that the inner and outer shields are insulated from each other. If the inner and outer shields are connected together, this will cause a short between and earth, which could cause electrical noise issues. 5 V Maximum cable length Readhead to interface: m Interface to controller: Clocked output option (MHz) 0 to 50 <0 analogue Dependent on clocked output option.
