Elesa+Ganter has launched a direct drive Electronic Position Indicator, DD51-E, with battery power supply. The device gives the possibility of reading the absolute or incremental positioning of a machine component. DD51-E, electronic and with battery power supply, joins its predecessors, the DD50, DD51, and DD52R. Its size makes it interchangeable with the mechanical version DD51; the 5-digit display, on the other hand, reminds of the DD52R. It is indeed thanks to the wide LCD display with 5 digits of 8.00 mm height that DD51-E ensures excellent readability even at a certain distance and from different viewing angles; the window in transparent technopolymer moulded over the case protects the display against accidental shocks. The ultrasonic welding between the base and the case avoids dust and liquid penetration, ensuring a high protection class (IP65 or IP67); this makes DD51-E suitable for applications requiring frequent washing cycles, even with water jets. The bushing and the pressure screw for the assembly to the shaft are made of AISI 304 stainless steel, to ensure high corrosion resistance. Through the three function keys, it is possible to select the different available functions (absolute or incremental mode, conversion of the unit of measure – mm/inches for linear measurements, degrees for angular measurements – selection of the origin of the absolute counter, selection of the offset value). It is also possible to program many parameters, including: reading after one revolution of the control shaft, maximum rotation speed, counting direction, display orientation and resolution (number of decimal digits displayed).
