DrawWorks O
tical Encoder
This specially configured DrawWorks Model HS35 encoder combines rugged, heavy-duty
features into a unique through-shaft style for use as a winch-turns counter in the
DrawWorks system of oil rigs. It incorporates dual bearings and shaft seals for NEMA 4
and 13 (IP65) ratings, a hard-anodized metal housing and a sealed connector. It comes
with a standard 1”-14 diameter threaded connection and a convertible adapter that allows
its use in systems with a 5/8”-18 threaded connection. This encoder has an UL, cUL, and
ATEX/CENELEC intrinsically safe rating when installed with the proper barriers (refer to
BEI P/N 924-60004-XXX series on the back of this specification sheet). This barrier is
high performance, galvanically isolated and carries US and European agency approvals.
It is suitable for ALL Hazardous locations, regardless of gas and dust types.
