Capacitive 6-axis force sensor(200N,500Ntype)

  • Capacitive 6-axis force sensor 
  • (Rated loads:Fx,Fy,Fz:200N Mx,My,Mz:4Nm)
  • (Rated loads:Fx,Fy,Fz:500N Mx,My,Mz:10Nm)
  • Model
  • WEF-6A200-4-RCD-B
  • WEF-6A500-10-RCD-B




200N type Model: WEF-6A 200-4-RCD-B is a 6 axis force sensor with rated loads Fx, Fy, Fz: 200N Mx, My, Mz: 4Nm.

500N type Model: WEF - 6 A 500 - 10 - RCD - B is a 6 - axis force sensor with rated loads Fx, Fy, Fz: 500 N Mx, My, Mz: 10 Nm.

As the advantage of the shape surface, connectors are vertically large in the case without connector case, there was a possibility of breakage, but by providing a connector case like RCD - B, the connector comes out in the sensor circumferential direction We have taken measures against damage with things. Since the installation and communication specifications are identical to the WEF-6A200-4 and WEF-6A500-10 which we have been using up to now, replacement can be easily done.


In addition, it was possible to attach a USB conversion cable or attach a DA conversion box because it enabled power supply of 5V to 24V.
