When this is the right choice
- 100 N five-finger grip. The strongest grip in the range, with 20 N at the four fingertips for a real pinch.
- 21 joints in total — enough articulation to reproduce a human grasp rather than approximate it.
- Built for data. Impact-resistant linkage and a 200°/s bend speed make it viable for high-intensity demonstration capture.
- 24–48 V and CAN / RS-485 — either a 24 V cell or a 48 V bus works.
When it is the wrong choice
- Wrist payload budget. 1.2 kg at the flange is a serious number for a 5 kg cobot arm.
- No tactile array. Fingertip forces are rated; for contact-rich data the L30 Pro carries an array.
- Simple pick-and-place. An O6 does the same job at a third of the mass and a fraction of the complexity.
Alternatives at a similar level
- Linker Hand L30 Pro — 17+4 DOF tendon hand with a fingertip tactile array
- Linker Hand L20 Lite — 10+10 DOF, 800 g, 80 N grip — the value version
- Linker Hand O30 — 20 direct-drive joints, 730 g, 30 kg
- Linker Hand O20 — 16 driven joints, 888 g, self-locking hold

Linker Hand L20 FAQ
L20 or L20 Lite?
L20 is 16 active + 5 passive at 1.2 kg with a 100 N grip; L20 Lite is 10 active + 10 passive at 800 g with 80 N. Lite for teaching and enveloping grasps, L20 when the dataset needs full articulation.
Why does a 1.2 kg hand matter for a dataset?
Because the arm accelerates that mass on every episode. A hand that articulates better can still lose if the arm is the bottleneck — check both against the arm’s rated payload.
Is the linkage repairable?
Yes — bolted linkages and joint modules rather than a sealed tendon path. Replacing a finger module is a maintenance task, not a factory return.
How long does it take to ship?
Confirmed per order at quotation.
