When this is the right choice
- Force control at 382 g. The -F version puts ±0.5% FS sensing inside a Φ52 frame — useful on fingers and small wrists that have to detect contact.
- Finger and small-wrist duty. 5.4 N·m at 100:1 is enough for a finger or a light gimbal.
- Same family ladder as RHU40H-130, so a hand built here and a leg built there share a supplier and a specification vocabulary.
- Two ratios, four published torque tiers. You can size on average load instead of a single peak number.
When it is the wrong choice
- Anything structural. 19 N·m start–stop is a finger figure.
- Where a brake is mandatory. The -F option is sensing; brake availability is confirmed per frame, so ask before you design around it.
- Cost-driven grippers. A planetary joint is cheaper where backlash is not the constraint.

RHU14L-52 FAQ
Does -F mean force control on the RHU series?
Yes. Unlike the PHU series — where -F is an output flange — the RHU -F suffix denotes the force-control (torque-sensor) version. Name it explicitly in the enquiry so there is no ambiguity between the two families.
How far up the range does force control go?
RHU-F stops at RHU25L-80. RHU32H and RHU40H have no built-in sensor version, so those axes need an external sensor.
50:1 or 100:1?
50:1 for speed on a finger that has to close quickly; 100:1 for torque and a quieter hold. The peak goes from 12 to 19 N·m with the higher ratio.
How long does it take to ship?
Confirmed per order at quotation.
