Notes:

  1. All models are equipped with limit switches adjustable within the specific ranges. When slip rings
    and rotary joints are used, the limit switches are disabled. Slip ring and rotary joints for continuous rotation can be installed upon request.
  2. Consult factory for definition of rotary joint i.e. frequency range, number of channels.
  3. Standard pedestal color is white. For other color consult factory.
  4. Standard operation temperature range is -20C to +60C. for extended temperature range consult factory.
  5. This pedestal series includes standard side arms. Special side arms and mounting table can be designed and provided according to specific user requirements.
  6. Base riser for pedestal can be designed and provided to user specified requirements.
  7. Pedestal details shown in the drawing are for reference only and should be specified in each order separately.
