Avtron HS25A Encoders easily fit shafts from 3/8" to 3/4", using a durable shaft insert. Units may be resized by replacing or removing the insert, enabling our factory, distributors, and customer stockrooms to swiftly meet any need. The shaft insert (3/8" to 5/8") also provides isolation from motor (read more)

Rotary encoders serve as measuring sensors for rotary motion, and for linear motion when used in conjunction with mechanical measuring standards such as leadscrews. (read more)

The HS35 now comes in a rugged 12 bit absolute hollow shaft design for precise position control. It has a variety of options: through or blind-shaft versions, a range of shaft bores and two tether options. The encoder carries an IP65 environmental rating and operates from 0º to 70º C (operation to 85º C available). With a depth of about 2 inches, this encoder makes for a very compact installation.
