BEI Sensors CHU9 Absolute Hollow Shaft Encoder - Manual

CHU9
PARALLEL ABSOLUTE SINGLE TURN ENCODERS, CHU9 RANGE
CHU9, 90mm parallel absolute single turn encoders :
 Especially designed for heavy-duty (steel, paper, wood – mills, cranes …) Compact and
robust conception. Excellent resistance to shocks/vibrations and to high axial/radial
loads.
 Through hollow shaft 30mm, reduction hubs available from 10 to 28mm.
 High protection level IP65.
 High performances in temperature –20°C to 90°C.
 Universal power supply from 5 to 30 Vdc – parallel output.
 High resolutions possibility, up to 14 bits (Gray or binary).
 Standard DIRECTION input.
 Double/triple mounting in combinations of incremental, absolute, analogue signals.
CHU9_25 connection CPR (radial M23), with reduction hub 9418/I25 (25mm) mounted on the shaft
