Typical Electrode Configurations

Disc with standard electrod

Disc with circular wraparound electrode

Disc with straight wraparound electrode

Disc with annular wraparound electrode

Other custom electrode configurations are available on request.

Dimensional Range
  • Diameter from 3mm (0.12”) to 254mm (10”)
  • Thickness from 0.08mm (0.003”) to 25.4mm (1”)

Custom sizes dimensions outside of the above may be possible – please consult for further information.

Standard Mechanical Tolerances
  • Diameter ± 0.150mm
  • Thickness ± 0.05mm

Tighter mechanical tolerances are achievable but are dependent on the disc diameter and thickness.

Metallisation Type
  • Standard metallisation: Silver fired thick film
  • Evaporated nickel
  • Electroless nickel - Gold flash
  • Gold over Nichrome - Evaporating (others available on request)
