BM20B-PUDSS-TFC

BM20B-PUDSS-TFC is a catalog/model number and isn’t identifiable without the manufacturer or context. If you share the vendor, I can give a precise, concise intro with the exact function and key specs.
In general, such a code usually designates an industrial component (often a motor/actuator, encoder, or drive). Likely parts of the name indicate: BM20B = product family/model, PUDSS = variant/options, TFC = configuration or connector/footprint.
A typical datasheet would cover:
- purpose and application (automation/robotics)
- main specs (torque/speed for motors or resolution for sensors)
- electrical requirements (voltage/current) and interfaces
- mechanical dimensions, mounting, and enclosure rating
- environmental ratings and connectors/wiring
If you provide the vendor, I’ll give a concise 1–2 paragraph introduction with the critical specs.

I don’t have enough info to confirm the pin count and function from the part number alone. BM20B-PUDSS-TFC could correspond to different BM20B series connectors from different manufacturers. Please provide the manufacturer or a link to the datasheet, and I’ll identify the exact pin count and each pin’s function.

I can’t determine the package type from that part number alone. Please share the manufacturer or a datasheet link for BM20B-PUDSS-TFC.
