Link-Touch raises Series D as force-sensor leader with 72.6% share
What's the deal? Chinese robotics force-sensor maker Link-Touch has closed a Series D round worth several hundred million yuan, led by GAC CapitalDealroom has a profile for this one. Try Dealroom →, the investment arm of automaker GACDealroom has a profile for this one. Try Dealroom → Group. Deye Co. and Xichen Capital joined as backers. The money will fund next-generation sensor development, capacity expansion, and global market rollout.
Why now? This is a quick re-raise. Since late 2025, Link-Touch has closed several rounds each worth over 100 million yuan, drawing backers including Sequoia ChinaDealroom has a profile for this one.

What does the company do? Founded in 2019, Link-Touch is one of China's earliest force-sensor developers. Its core team came from research bodies including the China Academy of Space Technology, the Chinese Academy of Sciences, and Beihang University, adapting high-precision force-control tech from aerospace to robotics.
Force sensors give robots a sense of touch, letting them gauge the interaction forces needed for precise, safe movement. That capability matters as humanoid robots move from demos into factories and homes, where tasks like precision assembly and flexible gripping require force feedback.
What's the endgame? Link-Touch holds a 72.6% share of China's humanoid-robot six-axis force sensor market, according to a 2025 report from GGII. Leading humanoid makers — including AgiBot, Galbot, Xiaomi, and UBTechDealroom has a profile for this one. Try Dealroom → — deploy its sensors at scale.
The company's six-axis and joint-torque sensors reach 0.1% FS accuracy, response above 10kHz, and 500% overload resistance, while a redesign cut sensor volume by 90% and weight by 80%. In Guangdong, Link-Touch has built what it calls China's first fully automated force-sensor line, with annual design capacity of 1,000,000 joint sensors and 200,000 end six-axis units. It has cut delivery times from the 6–8 weeks of overseas brands to 2–3 weeks.
Investor logic: Vice president Zhang Pengling said industrial backers bring more than cash. "What matters more is certainty of application scenarios," she said (translated from Chinese), noting that GAC and SAIC represent automotive manufacturing, CATL battery lines, and SMIC semiconductor production — settings where the company's sensors can deploy first. She added that AgiBot and Galbot were customers before becoming shareholders, a shift "from recognising the product to fully recognising the company."
The signal: The round underscores how China's industrial giants are moving upstream into the humanoid-robot supply chain, betting on component makers rather than just full-machine builders. With a dominant market share and factory-scale capacity, Link-Touch is positioned as critical infrastructure for a sector shifting from stage demos to real work.
