Parametrisable Rotary Encoder (magnetic / single-turn / analogue output)
Series ETA25PS
Errors and specications subject to change without notice
Shaft encoder for variable applications
Parametrisable via DIP switches
Angle 0..20° to 0..360° free congurable
Sense of rotation selectable (CW / CCW)
Supply voltage: 5 V / 3.3 V (switchable), 24 V
Analogue output: 0..5 V / 0..3.3 V (ratiom.), 0..10 V
High life expectancy >100 mio. shaft revolutions
Small housing case (ø25 mm)
Power save mode < 1 mA on request
Only one sensor for dierent applications. User friendly
to program. This saves money and time and simplies
the logistics. In combination with the long life expectancy
ETA25PS oers an outstanding price performance
relationship.
