When this is the right choice
- Fingers, small wrists, camera gimbals. 5.3 N·m at 370 g is the right order of magnitude where a bigger module would dominate the linkage design.
- Same protocol as the rest of the range. EtherCAT and CAN FD on a Φ52 frame means a finger axis can sit on the same bus as the elbow.
- A bore you can actually use. Φ8 mm is enough for a small harness or a sensor lead — rare at this size.
- Brake available. The -B05 variant adds a holding brake inside the same envelope for light vertical axes.
When it is the wrong choice
- Any structural axis. 19 N·m start–stop will not survive a knee or an elbow of a real payload — step up to TCHL-17 or TCHL-20.
- Force-controlled contact. There is no torque-sensor variant at this frame; the -TH2 option starts at TCHL-14.
- Shock-loaded axes. Harmonic drive, small frame — a planetary unit takes impact better at the same size.
Alternatives at a similar level
- TCHL-14 — One frame up — 6.5 N·m, 0.45 kg, Φ65 × 55 mm, torque-sensor option available
- Crabnova CE-RB-R48-101-Lite — 5 N·m rated harmonic at 0.26 kg, Φ48 frame
- DAMIAO DM-J4310 — 3–5.2 N·m planetary at 306–370 g, 24 V, no brake
- Crabnova CE-RBV3-R48-101 — 6.5 N·m with brake and torque sensor built in, 0.276 kg

TCHL-11 FAQ
Three ratios on a 5 N·m joint — does it matter?
Yes, more than at the big frames. At this size the output speed is what you feel: 50:1 gives the fastest finger motion, 100:1 the most torque and the quietest hold. For a finger that has to close in under 0.3 s, 50:1 is usually the answer.
Can I get a torque sensor on TCHL-11?
No. The -TH2 and -B05-TH2 variants start at TCHL-14. If you need force feedback on a joint this small, the sensor has to be external or you move up a frame.
Is the brake worth 0.1 kg?
Only on a vertical axis that must not drop at power-off. On a finger it is usually dead weight.
How long does it take to ship?
Confirmed per order at quotation — it depends on ratio, brake option and what the factory has built. The quotation carries the date we are working to.
