Incremental linear encoder GVS 202 S T series

opticalmechanicalstainless steel

Optical incremental scale with stainless steel measuring support. High mechanical resistance and thermal expansion suitable for the application, for a constant accuracy at any temperature. Particularly suitable for applications on synchronized press brakes. Transducer guided by a self-aligned and self-cleaning sliding carriage with spring system. No contact reader head. No friction: high duration and tolerance against environmental dirty. Measuring length up to 30.000 mm, in modular version. Accuracy grade ± 2.5 μm in the standard version and ± 1 μm in the high-accuracy version. Metrological certificate provided with each scale. 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 to both columns of the press brake. Safety limit switches, positionable at both ends. Sealing lips for the protection of the grating, made of special elastomer resistant to oil and wearing. Self-blocking special profile. Various possibilities of application, with double-effect joint or steel wire. Interchangeable with GVS 2xx line and with the previous model PBS-HR. High accuracy and stability of signals even in case of high speed, strong accelerations and vibrations. Protected against inversion of power supply polarity and short circuits on output ports.
