Some applications such as fighting vehicles and aircraft require the IncOder casework to be electrically earthed. The standard IncOder housing finish is hard-anodized which is non-conductive. A connection can be made using an earthing strap with a crinkle washer which penetrates the anodized surface. Alternatively, remove the anodized surface in the immediate vicinity of the strap (usually located using one of the attaching screws) using a file or abrasive. Alternatively, conductive finishes such as Alocrom or Surtec650 may be requested from the Extended Product Range.
