Celesco OEM Series cable-extension position transducers offer a low-cost solution for design engineers that require precision position and velocity measurements in a high-performance, compact assembly.

Celesco OEM position transducers are compact, felxible and accurate measurement devices engineered to customer specifications.   Models can weigh less than  pound and be less than 2" high when retracted, yet measure out to 60".  These high-quality, reliable potentiometer and incremental encoder output devices detect and measure linear position and velocity using a flexible cable and spring-loaded spool, generating a proportional electrical signal.  The rugged stainless steel measuring cable does not have to be perfectly aligned, making installation fast, simple and trouble-free.

OEM Series Custom Modifications.  The standard Celesco OEM-Series transducer assemblies shown here can be simply modified to meet specific requirements.  Circuits can be added for regulated output.   Designs are available with and without covers and can be engineered for drop-in replacement of current assemblies.  They allow for custom mounting, custom electrical connections and customer-specified life testing.  Quantities are available as small as 100 units.

High Performance Applications.  Small size and high accuracy make Celesco OEM Series ideal for medical and dental equipment; also fitness, commercial and industrial equipment.  Whether you can use a standard OEM series assembly or require a new design (measurement ranges to 450"), contact Celesco for the low cost, reliable position measurement solution.
