Hollow Shaft Incremental Rotary Encoder OD 80mm ID 30mm 2000 P/R IP50

Series: IHA8030 Series

Hollow shaft encoder, axis inside diameter30mm, (28mm, 6.25mm, on order), housing diameter 80mm.
With flex bracket flange, easy for installing, light weight, stable output.Rugged and extremely thin hollow shaft encoder for extension on power motors.


Power motors and three phase current motors with frequency transformation, system construction, elevator systems.
Output waveform:90 output phase difference, CW rotation( CW rotation as seen from fit surface)

Square-wave accuracy:Pitch error of peridor: ±0.01T
Pitch error of phase position: ≤1/18T
Z phase of pulses: T=360°/N (N: output pilses)
Signal accuracy: Xn=1/4T±1/12T(n=1,2,3,4)
A leads B clockwise when viewing the encoder shaft end.
The position of Z phase against A,B phase is not specified
