The HS45 is a large bore, heavy duty, rugged encoder designed to operate in very demanding environments. It is available in both single and dual output versions as shown. These encoders use a preloaded bearing set for mechanical stability and a long service life. The dual output version has redundant electronics internal to the encoder simplifying signal distribution to multiple controllers. Special Models of the HS45 Incremental Encoder are available with one or more of the following certifications.
