Mechanical & Environmental Specs
Built on the same rugged design as the incremental model, the HS35
Absolute Encoder is available with various output options including
Gray Code and Natural Binary. Designed with a cast aluminum hous-
ing, a sealed connector and shaft seals, it carries an IP65 environ-
mental rating. With the optional insulating inserts, it can be mounted
on smaller diameter shafts. It is designed for either a through shaft
mounting or blind shaft mounting with a closed cover to maintain its
environmental rating.
Shaft Bore: many diameters from .375 to 1.000 inch are available, including metric.
(Consult factory for details)
Allowable Misalignment: 0.005” T.I.R. on mating shaft 0.75” from shaft end
Bore Runout: 0.001 T.I.R. maximum
Starting Torque at 25°C: Through shaft version (SS) = 7 in-oz (max);
Blind shaft version (BS) = 4 in-oz max
Bearings: 52100 SAE High carbon steel
Shaft Material: 416 Stainless Steel
Bearing Housing: Die cast aluminum with protective finish
Cover: Die cast aluminum with protective finish

Moment of Inertia: 0.019 oz-in-sec
The HS35 Absolute Encoder is available with the following certification:
EN 55011 and EN 61000-6-2
Weight: 18oz typical
Temperature: Operating, 0° to 70°C; Extended temperature ratings are available in the
following ranges: -40 to 70°C, -40
to 85°C. Extended temperature ranges can affect other perfomance factors.
