HEIDENHAIN RCN 223 533117-01 RCN 223 digital sensor

The RCN 223 series usually adopts the absolute single-turn measurement principle with a resolution of up to 23 bits (8388608 positions/turn). The system accuracy may fluctuate between ±2.5'' and ±5'' depending on the version. For example, the system accuracy of model 362277-01 is ±2.5'', while that of 533117-03 is ±5''. If 533117-01 belongs to this series, its accuracy may be within this range, which needs to be judged in combination with the version number.

(II) Electrical characteristics

Output protocol: Common interfaces of this series include Fanuc 01, Fanuc 02, EnDat 2.2, etc. For example, 362277-01 adopts Fanuc 01 protocol, and 533117-03 is Fanuc 02. If 533117-01 is a customized version, it may be compatible with specific CNC systems (such as Siemens, Mitsubishi), which needs to be confirmed by the official.

Power supply voltage: The power supply range of standard models is usually 3.6V to 5.25V (such as 533117-03) or 5V±5% (such as 362277-01), depending on the interface protocol and internal circuit design.

(III) Mechanical design

Hollow shaft structure: The RCN 223 series is equipped with a 20mm through hollow shaft as standard, which supports axial clamping and is easy to integrate into the rotary table or spindle drive system.

Flange and protection: 85mm rectangular aluminum flange with centering ring, end cover integrated guide groove, protection level IP64 (dust and splash water proof), suitable for complex environments such as machine tool workshops.

(IV) Compatibility and Application

This series is widely used in CNC machine tools (such as the rotary axis of five-axis machining centers), automated testing equipment (such as angle measurement of electronic components) and coordinate measuring machines (CMMs), etc., and improves the reliability of processing and testing through high-precision angle feedback. If 533117-01 is a specific version, it may be optimized for high-speed or high-dynamic response scenarios.

2. Analysis of differences with other models

(I) Comparison with 533117-03

Accuracy difference: The system accuracy of 533117-03 is ±5'', while that of 362277-01 is ±2.5''. It is speculated that 533117-01 may belong to the intermediate accuracy level.

Interface protocol: 533117-03 uses Fanuc 02 protocol, while 362277-01 is Fanuc 01. 533117-01 may be adapted to different CNC systems or communication standards.

Power supply range: 533117-03 supports a wide voltage input range of 3.6V to 5.25V, while 362277-01 supports 5V±5%. If 533117-01 is a customized version, the power supply design may be adjusted to suit specific devices.

(II) Comparison with RCN 2001/5001 series

RCN 2001/5001 series (such as RCN 2390F) supports higher accuracy (±2'') and higher speed (3000rpm), and integrates temperature sensors. In contrast, RCN 223 series focuses more on cost-effectiveness and is suitable for scenarios with medium and high precision requirements.
