Applications

Where the WST611 Works Best

Miniature Press Force Monitoring

Embedded in miniature assembly machines and micro-press stations, the WST611 returns millinewton-resolution reaction force without enlarging the tool envelope.

multiple capacity options range

Robot End-effector Tactile Sensing

Mounted at the wrist or fingertip, the WST611 gives collaborative and surgical robots a sense of touch — enabling delicate pick-and-place and assembly verification.

Miniature envelope

Medical Device Force Feedback

Inside disposable and reusable medical devices the WST611 monitors injection, occlusion and contact forces, supporting closed-loop safety logic.

Electrical Notes

  • Shielded cable; keep away from motor/power runs, ground the shield at the indicator side

Mounting Checklist

  1. Mount on a rigid, flat base
  2. Torque mounting screws evenly; avoid over-torque that preloads the measuring element
  3. Keep the load applied through the intended loading axis; verify alignment before calibration
  4. Verify zero balance before calibration, then calibrate with certified test weights
