ELESA HAS STANDARD COMPONENTS FOR PRINTING AND PAPER PROCESSING MACHINES

The Elesa DD51 and DD52 direct drive Digital Position indicators are 4 and 5 digit sealed case units in a high impact technopolymer housing which is ultrasonically welded making them ideal for shaft drive position readouts in industrial environments. This aspect is further enhanced by the availability of an additional front seal to prevent ingress of dust in arduous conditions to a level of IP67, and of stainless steel reduction sleeves. Reduction sleeves allow the shaft size accommodated to go from 14mm down to 6mm in the DD51 and from 20mm to 12mm in the DD52.

Where delicate manual control is vital, then sensitive micrometer adjustment can be provided by the new Elesa GN727 in either flange or side mounting formats. The GN727 provides accurate control of spindles, lead screws etc with either precise adjustment or alignment to a positive stop position. Operation has been achieved without backlash for smooth forward/reverse transitions in either 10 or 15 rotation mode – with each rotation corresponding to one millimetre and each of 50 graduations on the adjuster knob corresponding to 0.02mm.

The unusual Elesa CFA/F is an external multi-leaf thermoplastic hinge with inbuilt 90º stop. It is ideal for machine guards, small equipment housings, or for access doors where the opening angle must not exceed 90º. The 90º door stop feature may be important in many situations to prevent a door interfering with other nearby equipment, or to prevent excessive opening in windy conditions. The system is safe and secure for operator's hands as it is a built-in function of the hinge mechanism, thus leaving the operator free to work on the machine or equipment.
