Wire incremental transducers

EFA4000, EFA5000, EFA6000, EFA8000, EFA10000, EFA12000 are incremental wire transducers that turn a linear motion into coded digital pulses. They are made of an incremental optical encoder activated by the stroke of a winding or unwindingstainless steel wire (0,1 mm. the resolution with quadruplied count).
A special feature is their easy assembling.
Analogue outputs are provided.
The linking together to a display or an electronic positioner (for example FIX5, F2X,P1X) supplies a simple, effective system to measure linear or angular motions on machine tools, automatic-,wood-, marble-, glassworking machinery, cylindrical-, hydraulic-, pneumatic stroke, shutiers, etc.
These transducers are carried out in case in oxidized aluminium.

The P_X positioning units serie are programmable microprocessor single-axis positioner with relay or analogue outputs that processes signals supplied by incremental transducers such as encoders, optical lines, and magnetic band. 
• P1X: the 16-key keypad and 8 operation indicators make operating and setup of the positioners user-friendly. 
• P2X: programming is done very easily by four keys on the front panel; an auxiliary display allows a two character-driven programming in addition to displaying parameters during processing.
 for more complete information, see sec. "Displays, impulse counters, positioning units, ..." in the drop-down menu on the left.  

The F_X series are mono-bidirectional display unit with microprocessor with display, particularly suitable for the measurement of linear and angular dimensions with signals supplied by incremental transducers such as encoder and optical lines, magnetic band, 
• F1X5: mono-bidirectional display unit with microprocessor and six-digit display (reading scale -99999 +999999). 
• F2X: an auxiliary display with two characters enables the guided programming of the display unit. 
• A3X: programmable mono-bidirectional multifunction counter with three axes on 6-digit displays, (reading scale -99999 +999999), ideal solution for all the cases in which it is necessary to display the position on machines with three axes (honing machine, milling machine, etc.).
