tentac.co.jp zoominfo.com/c/tentac-co-ltd/458253608 TENTAC Co., Ltd world's leading maker of robotic tool changers — automatic docking systems that let industrial robots swap end-of-arm tools (welding torch → gripper → spray gun → grinder) mid-production without stopping the line. Founded 1968 as a Kobe Steel division, spun off independent in 1985; HQ in Kobe, Japan; ~35–40 employees, ~¥1.5–2B revenue — yet claims up to 80% global market share in robot docking systems. Technology: micron-level positioning repeatability, safety locks (tool stays attached even on pressure loss), and media-passing (electricity, pneumatics, hydraulics, water, signals) through the joint — payload classes from a few kilos to automotive body-welding weights; embedded as the de-facto standard by Japanese (Fanuc, Kawasaki, Yaskawa) and European (ABB, KUKA) robot integrators. Diversification from the same precision-mechanics core: inertial gyro sensors (marine, construction) ISO 9001/14001 certified.
