M6C-4S1HX51ZTZ00 is a hollow shaft incremental encoder designed for end-of-shaft mounting. For this model, we have developed a customized product matched to the original installation conditions. Except for the fixing bracket design, the main mechanical mounting dimensions are kept consistent with the original unit, making it suitable for maintenance and replacement on existing equipment.
The encoder uses a 1 inch (25.4 mm) hollow shaft bore and is secured to the machine shaft with a clamping collar. In the model code, 51 corresponds to a 512 base PPR, while the H high-range output results in 1024 PPR. The encoder also includes a Z Marker reference signal and uses a terminal-box connection.
For this type of hollow shaft encoder, replacement involves more than confirming the 1 inch bore size. Shaft engagement, the clamping arrangement, and the method used to prevent the encoder housing from rotating with the machine shaft are also important. The original series uses an anti-rotation bracket that allows a certain amount of shaft end float without creating a rigid mechanical constraint.
The customized version uses a triangular fixing bracket, which is one of the most visible structural differences from the original product. This bracket is used to secure the encoder housing and prevent it from rotating with the shaft, while the other key mounting dimensions remain matched to the original installation.
The customized encoder operates from 10–30 VDC. The incremental signal configuration is matched to the existing equipment, while the A/B phases, Z Marker, and wiring definitions should be confirmed before installation to ensure that direction and reference-position signals are correctly recognized by the control system.
For M6C-4S1HX51ZTZ00, the two main points in this customization are the 1 inch hollow shaft fit and the triangular fixing bracket. The remaining main mechanical dimensions are matched to the original product to reduce the need for modification to the existing installation.
