Blind hollow shaft incremental encoders launched

A SICK product story

Edited by the Manufacturingtalk editorial team Feb 18, 2008

Blind hollow shaft incremental encoders provide added protection against contaminants such as dirt and water and can be used in dusty environments with water washdown cleansing.

SICK Stegmann's DFS 60 Incremental Encoders are now available in blind hollow shaft versions.

These blind hollow shaft encoders significantly reduce the potential for contamination by dust, dirt or water, making them well suited for use in dirty or dusty environments with water washdown cleansing, said the company.

Typical 60mm encoders offer 1024 ppr, up to 8192 ppr.

DFS60 blind hollow shaft encoders deliver from 1 to 65,536 ppr.

They also provide reliable operation in temperatures ranging from -20 deg C up to +100 deg C.

SICK Stegmann told manufacturingtalk.com that most optical encoders are typically rated for use in operating temperatures up to 70 deg C.

President of SICK Stegmann, Scott Hewitt, said: "Unlike most conventional optical encoders that have a glass or plastics rotating disc, DFS 60 encoders boast a unique nickel code disc that delivers significantly more robust and reliable operation than conventional encoders in heavy duty industrial applications".

A radial/axial cable outlet reduces installation depth and allows a single encoder type to be used for various applications.

An integrated stator coupling is housed in spring steel to increase bearing life, allow error free angle measurement, and allow users to adjust the shaft and axial movement of the motor shaft.

They are available with a TTL or HTL interface.
