Single Turn and Multi-Turn！

As the name implies, single turn encoders are best suited for short
travel, motion control applications where position encoder verification is required within a single turn of the encoder shaft. A multi-turn encoder is recommended for applications involving lengthy or complex positioning requirements.
A multi-turn encoder consists of a series of disks connected to the basic
high resolution disk through a system of gearing. The additional disks
provide for turns counting so that position data is available over
multiple revolutions. The Ledex multi-turn absolute encoder features
4,096 turns with a resolution of 4,096positions/turn.
