What is the difference between Sin/Cos and TTL encoders?

Difference between encoder types

The Safeone DS module has a safety-related encoder input (RJ45) that can process both signal types, Sin/Cos and TTL

Sin/Cos-Encoder

Sin/Cos encoders provide sinusoidal and cosinusoidal signals for high resolution and accuracy.

TTL-Encoder

TTL (Transistor-Transistor-Logic) encoders provide a digital square wave signal and are widely used.
