Linear encoders - type TGM

Iskra TELA d.d manufactures linear encoders - type TGM, which are opto electronic incremental encoders applied in numerous industrial areas for high precision position measuring on machine tools, positioning systems and robotics. The scale and the reading head of these encoders are protected against the influence of industrial environment (dirt, coolant, water and chips). These linear encoders are used primarily on conventional or NC metal working machine tools (lathes, milling machines, grinding machines, coordinate boring machine tools, EDM, machining centres and other machine tools). Technical specifications: Type of linear scales TGM: standard DRO linear encoders Model name: TGM 111 Output signals: SO = sine voltage, DO = square wave and DI = square wave with inverted values Engraving pitch: 20 or 40?m Resolution: available - 1?m, 2?m, 5?m, 10?m Accuracy (at 20 C/68 F): ?3?m (Lm < 520mm), ?5?m, ?10?m Light source: IR LED Photo detector: Phototransistor Cross section: 20 x 32 mm Reference mark: TGM111 - optionally each 100mm Operating temperature: 0 to + 50 degree Celsius, (32 to 122 degree F) Storage temperature: -30 to + 70 degree Celsius, (-22 to 158 degree F) Humidity range: 30 to 90 per cent (no condensation) Protective design grade (class): Normal IP53; with air purge Atmosphere: Corrosive gas should not be contained in the atmosphere Vibration resistance: 30m/s2 Shock resistance (max shock): 100m/s2 Maximum response speed: 45m/min Power supply: +5V?5 per cent, +12V?5 per cent, +/-12VAC Power consumption: 100mA maximum Cable length variations (total permissive cable length) 3m standard, optionally up to 50mm
