ITD 40 + FS B10 Y 4 500 H BI 2XKKR S 11 IP65 is a combined unit integrating an incremental encoder and a mechanical centrifugal speed switch. For equipment that is still using this model, we can develop a customized product based on the original mounting dimensions and main electrical parameters for maintenance and spare-part replacement.

The encoder series supports pulse counts of up to 1024 pulses per revolution, while this specific configuration is rated at 500 PPR. ITD 40 + FS B10 Y 4 - Baumer Th… ITD 40 + FS B10 Y 4 - Baumer Th… The output uses an HTL configuration and provides A and B incremental channels with a 90° phase shift, together with the corresponding inverted signals. ITD 40 + FS B10 Y 4 - Baumer Th… ITD 40 + FS B10 Y 4 - Baumer Th…
Mechanically, the unit uses a B10 mounting design with an 11 mm solid shaft. The centering diameter is 85 mm, and the mounting pitch circle diameter is 100 mm. The customized product is designed to retain the original mounting dimensions, so the existing installation position does not need to be modified.

The FS section is a mechanical centrifugal speed switch. Its switching-speed range is 800–3000 rpm, with an accuracy of ±5% of the selected switching speed. This function is independent of the encoder pulse output and is used for speed monitoring or interlock protection. ITD 40 + FS B10 Y 4 - Baumer Th…
The original HTL version operates from 8–30 VDC, while the customized product uses 10–30 VDC. ITD 40 + FS B10 Y 4 - Baumer Th… This is one of the differences that should be confirmed before replacement.
For this model, the customized solution focuses on retaining the 500 PPR output, original mounting dimensions, and FS speed-switch function, while changing the supply range to 10–30 VDC. This allows the encoder to continue serving the existing machine without changing the original mechanical installation.
