The RO3104 is an incremental encoder with a hollow shaft designed for precise rotary measurement. It provides configurable resolution from 1 to 10,000 with a factory setting of 1,024. The encoder operates from 4.75 to 30 V DC and provides HTL/TTL output capability. Its 15.875 mm hollow shaft suits direct machine-shaft installation. IO-Link provides digital parameterisation and diagnostic functionality.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The RO3104 uses magnetic sensing to generate a defined incremental pulse sequence. Its A and B signals have a 90° phase difference for direction detection. The encoder supports a switching frequency of up to 1 MHz. Its maximum electrical speed is 12,000 rpm. These characteristics make it suitable for fast rotary feedback applications.
The encoder uses a 15.875 mm hollow shaft open on one side. This shaft size corresponds to a 5/8-inch mounting format. Direct mounting reduces mechanical coupling components. The housing has a diameter of 58.5 mm. The overall length is 83 mm.
IO-Link enables electronic configuration of the encoder. Resolution, rotation direction, HTL, and TTL parameters can be configured. The encoder supports IO-Link 1.1 with COM2 transmission at 38.4 kBaud. SIO mode is supported. Digital parameterisation simplifies machine commissioning.
