Basically we distinguish between 2 types of rotary encoders: absolute and incremental.
1. Absolute encoders (Single and multi-turn absolute encoders)
Absolute Encoders always provide the actual position (by a coded angle information) at the system power on, despite possible shaft rotations; therefore there is no need to reset to the zero point after a power down. For each mechanical position, absolute encoders provide a unique voltage or binary count.
Our single and multi turn absolute encoders are the cost-effective solution to control motions on operating machines in all industrial application areas. Not only with very high resolution, also with extreme precision. The wide choice of mechanical solutions allow to fulfil any application requirement. The different available output signals and voltage supply range make it possible to interface our absolute rotary encoders to any counting system or PLC controller.
2. Incremental encoders (Incremental rotary encoders)
Incremental Encoders are rotary transducers used to control length or thickness measurements, angles and speed. Basically they provide a square wave or sinusoid output signal. By turning an incremental encoder on, the position of an incremental encoder is not known since the output signals do not refer to any singular position. Incremental encoders are commonly employed on industrial operating machines, combined to counting, visualising or control systems, to achieve programmed displacements, such as length and positions, preset step shifts or simply to display physical measurements. Thanks to the innovative electronic circuitry and the high quality of the components, our encoders ensure high resolution, great accuracy and repeatability at very low cost. The very wide choice of mechanical and electronic variations ensures us to meet all your application requirements.
