Made from hardened steel or treated alloys to resist wear,
deformation, and corrosion.
Critical for Placement Accuracy
Ensures correct release timing and positioning of components during
the placement cycle.
Compatible with Multiple Head Models
Used in FUJI working heads where ejector pins are required as part
of the internal mechanism.
Applications
Helps to push components off the nozzle or holding device during
placement.
Supports the release phase in the pick-and-place cycle, avoiding
component sticking or misplacement.
Essential for high-speed, accurate SMT assembly lines.
