Laser Ceramic Ring D28-M11-H12 (WTC-01A)
This ceramic ring is a precision insulating component for fiber laser cutting heads. It holds the cutting nozzle and electrically isolates it from the head body, which lets the capacitive height sensor read the standoff distance correctly. Its heat-resistant ceramic body also withstands the radiant heat and spatter at the cutting zone. Dimensions are fixed by the D28-M11-H12 designation, so the ring seats straight into the head that uses this standard.
