The nozzles are turned from brass. Mounted onto them is a ring magnet that holds them on the placement head together with the second magnet on the lower end of the hollow shaft stepper motor. They must be protected from slippage. I am using a piece of silicone pad that is shown on the pictures below. I have now replaced the silicone pad on the nozzles by a silicone pad underneath the rotary axis. I have also painted the lower part of the nozzles that are used for component alignment matte black.
Up to three nozzles can be placed into a nozzle holder. They will be changed automatically.
