SSI ABSOLUTE SINGLE TURN ENCODERS, CHU9 RANGE
CHU9, 90mm SSI 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 – SSI output.
High resolutions possibility, up to 16 bits (Gray or binary).
Standard DIRECTION and RESET input.
Double/triple mounting in combinations of incremental, absolute, analogue signals.
Digital or sine incremental outputs option.
CHU9_25 connection S6R (radial M23), with reduction hub 9418/I25 (25mm) mounted on the shaft
