An encoder provides digital output signals (pulses) using optical, magnetic, or capacitive sensing, while a resolver provides analog sine/cosine signals using electromagnetic induction. Encoders are typically used for higher resolution, while resolvers are more robust in harsh environments.
TTL (Transistor-Transistor Logic) is suitable for short distances (up to a few meters) and lower voltage levels, while HTL (High-Threshold Logic) is designed for longer distances and higher noise immunity. The choice depends on the cable length and the electrical environment of the application.
IP (Ingress Protection) rating per IEC 60529 indicates resistance to dust and water. IP54 means limited dust protection and protection against water splashes, while IP67 means dust-tight and protection against temporary immersion. Higher ratings are suitable for harsher industrial environments.
Resolution, measured in bits, determines the smallest increment of position that can be detected. Higher resolution (e.g., 23-bit) allows smoother motion control and finer positioning, which is critical for high-precision applications like CNC machines or robotics.
