TECHNICAL DATASHEET code ST04 project A50 I release D GENERAL FEATURES • Incremental magnetic scale with pole pitch 2+2 mm. High mechanical resistance and thermal expansion suitable for the application, for a constant accuracy at any temperature. • Particularly suitable for synchronized press brakes. • Reader head guided by a self-aligned and self-cleaning sliding carriage with spring system. • Reading without contact. • Selectable reference indexes, every 10 mm along the entire measuring length, with Zero Magneto Set device. • The adjustable cable output and the selectable zero references make the scale symmetric and applicable, in the same version, to both columns of the press brake. • Various possibilities of application, with double-effect joint or steel wire. • Option: safety limit switches, positionable at both ends. Measuring support - Pole pitch - Linear thermal expansion coefficient plastoferrite on stainless steel tape 2+2 mm 10.6 x 10-6 °C-1 MECHANICALCHARACTERISTICS Rugged and heavy PROFILE, made of anodized aluminum. Dimensions 55x28 mm. Elastic COUPLING for misalignment compensation and self-correction of mechanical hysteresis. SEALING LIPS for the protection of the magnetic band, made of special elastomer resistant to oil and wearing. Special self-blocking profile. CARRIAGE guided by ball bearings with gothic arch profile sliding on tempered and grinded guides, to guarantee the system accuracy and the absence of wearing. Die-cast TIE ROD, with nickel surface treatment. MAGNETIC BAND on stainless steel support. High mechanical resistance and linear thermal expansion suitable for the application. Elastomeric GASKETS which allow to reproduce the full protection in mechanical joints (in case of disassembling). Adjustable CABLE output. Various possibilities of application, with DOUBLE-EFFECT JOINT or STEEL WIRE.
