What it is

The Siemens ASZ12.733 is a potentiometer rated at 1000 ohm with a 135 degree rotation angle. It is a control component used on Siemens oil-fired boiler equipment, where the potentiometer tracks the position of a rotary control and feeds the corresponding resistance value back to the boiler control. The part is supplied under the Siemens brand designation ASZ12.733.

Before you order

  • Confirm the part number ASZ12.733 matches the marking on the existing potentiometer or the boiler documentation.
  • Check the required resistance value is 1000 ohm and the rotation angle is 135 degrees for the control being replaced.
  • Inspect the failed component and its mounting and connection arrangement before ordering, as no fitment data is supplied with this listing.
