DF40C-80DP-0.4V(51)

That part code looks like a vendor-specific model for a compact 40 mm gearmotor (DF40C). In many catalogs, DF40C denotes a 40 mm frame motor, and 80DP often refers to a gearbox option (roughly an 80:1 ratio), with 0.4V(51) likely a variant code or option set. There isn’t a universal datasheet for this exact string, so precise specs (voltage, torque, speed, encoder, shaft) depend on the manufacturer.
If you share the vendor or a link, I can give a precise introduction. In general, a DF40C-80DP-type gearmotor is a small, high-torque-at-low-speed actuator suitable for robotics and automation. Typical things to verify:
- Motor type and nominal voltage
- Gearbox ratio and output torque
- Speed (no-load and loaded)
- Encoder options and resolution
- Shaft size, mounting flange, and connector/lead options
I can summarize the exact model once I have the datasheet or manufacturer.

DF40C-80DP-0.4V(51) is a Hirose fine‑pitch FFC/FPC connector. Key features:
- 0.4 mm pitch, 80 contacts, dual‑row (DP)
- Vertical/mount type suitable for SMT board mounting (0.4V variant)
- FFC/FPC compatible: supports cable thickness ~0.3–0.4 mm
- Copper alloy contacts with gold plating
- Electrical: rated ~50 V, ~0.5 A per contact
- RoHS compliant
- Typical operating temp range: −25 to +85 °C
Note: exact locking/actuation (ZIF/LIF) can vary by sub‑variant.

- Pin count: 80 pins (dual-row)
- Function: Hirose DF40C 0.4 mm pitch FPC/FFC connector used to mount a flexible printed circuit to a PCB (board-to-FPC connection).

I can’t reliably identify the manufacturer from that model alone. DF40C-80DP-0.4V(51) isn’t uniquely mapped to one company. Please share a link, datasheet, or product category (servo motor, gear, etc.) so I can name the maker and describe the company.

A Hirose DF40C series board-to-FPC connector: dual‑row, 0.4 mm pitch, 80 positions, vertical mount.
