How to keep your »cool« when the going gets hot.
ITD 61 A 4 Y 9 hollow-shaft encoders. Water-cooled.
In a hot environment, it is essential to provide temperature-sensitive  electronic components in encoders with thermal protection if you want to keep  system availability high. 
Water-cooled encoders in the ITD 61 A 4 Y 9 series, originally a special  development for a one-off application, guarantee consistently high performance  quality even when ambient temperatures are high. For example:  
    
        
            | 
             ■ 
             | 
            
             in close proximity to engines with high temperatures of their own, like diesel    engines, 
             | 
        
        
            | 
             ■ 
             | 
            
             in the glass and ceramics industry, or 
             | 
        
        
            | 
             ■ 
             | 
            
             in foundries and other plants involved in metalworking.
