Every unit is factory calibrated and inspected before dispatch; parameters on this page reflect shipped goods.
Embedded in miniature assembly machines and micro-press stations, the WST604 returns millinewton-resolution reaction force without enlarging the tool envelope.
multiple capacity options range
Mounted at the wrist or fingertip, the WST604 gives collaborative and surgical robots a sense of touch — enabling delicate pick-and-place and assembly verification.
Miniature envelope
Inside disposable and reusable medical devices the WST604 monitors injection, occlusion and contact forces, supporting closed-loop safety logic.
