Aftermarket ceramic nozzle holder for Raytools fiber laser cutting heads. Replaces Raytools 120515089A: 41 mm across, 12.9 mm high, with an M11 x 0.75 brass thread for the M11 nozzle used on high power heads.
It sits between the head and the nozzle: it insulates the nozzle so the capacitive height sensor reads only the gap to the sheet, and it holds the nozzle in line with the beam. A cracked or dirty ceramic shows up as height sensing alarms and nozzle crashes.
It fits the Raytools BS12K, BS15K and BS20K heads that use this ceramic. Sold in packs of 1, 5 or 10.

After a head collision
A crash into a tipped part or the sheet edge usually cracks the ceramic before anything else. A spare gets the machine cutting again in minutes.
Height sensing alarms
Erratic capacitive readings, height jumps or false collision alarms are often a cracked or dirty ceramic. Swap it before recalibrating the sensor.
High power heads
On 12 kW and above, spatter and heat age the ceramic faster. Keep a spare for every head.
Planned maintenance
Inspect the ceramic at every nozzle change and replace it when chips, cracks or heat discolouration appear.
