I currently use rotary encoders. Can I use linear encoders?！

The suitability of a linear encoder for a particular application is dependent on many factors, some mechanical and some electrical. From a mechanical perspective, the type of measurement required and the mechanical feasibility of integrating a rotary or a linear encoder will often dictate one over the other. From an electrical integration standpoint, LN linear encoder provides industry standard differential quadrature outputs and is therefore compatible with the same displays, controllers, PLC's and counters that an incremental rotary encoder would be. The LN linear encoder offers integrators the flexibility to use the same interface devices as with their rotary encoders, eliminating the need to retool an entire control system.
