DYNAPAR brand sealed hollowshaft encoders are now available in size 20 (2 inch) configuration. The Series HS20 mounts directly to machine or motor shafts using a hollow, floating shaft mount and simple, anti-rotation spring tether.

Robust metal hub and flexible spring mount allow for easy installation on motor or machine shafts. This type of mounting reduces the encoders installed-depth and also lowers installation cost.

Available with English and metric hub sizes ranging from 1/4" to 5/8" and 6mm to 16mm, the HS20 includes precision bearings and seals at both ends of the hollowshaft. Resolutions to 2500 PPR permit the HS20 to be used in feedback applications requiring utmost precision.

Additional features include: LED light sources; matched sensors; operating speeds to 100kHz; and a NEMA 4 / IP65 rating. A 5-26 V dc line-driver, with complementary outputs, is available for long cable runs and high electrical noise immunity.

Outputs are compatible with most 5 volt TTL circuits, as well. An LED output indicator option shows the status and phasing of all electrical outputs, greatly simplifying installation setup.

Typical applications are motor-mounted feedback, industrial equipment, assembly machinery, and robotics. Micromax 1300 362 626.
