MiniCoders are designed for installation in drives as an alternative to the conventional encoders.

 

They are contact-less and are equipped with a magnetic scanning system which, in conjunction with a toothed wheel as measuring scale, permit the measurement of rotary motion. This solution is exceptionally space-saving.

 

For the measurement of linear motion, a pitch structure in a piston rod can be detected by the MiniCoders.

 

The sensor elements, the magnet and the integrated electronic system are incorporated in state-of-the-art microsystem technology and are fully encapsulated.

 

The design together with subsequent circuitry ensures an electrically and mechanically robust product.

 

 

advantages

 

MiniCoders are dew-point proof, do not wear and are insensitive to dirt, shock and vibration. The measuring scales can be so designed that every machine geometry be accommodated (interior and exterior diameter, impulse number). MiniCoders require no maintenance and thus have a low cost of ownership. This extremely flexible system offers you not only long term reliability but also solutions to gain a competitive edge.

he incremental encoders are used to convert rotary motion into electrical impulses.
