helix-e docking
adjustable software controlled z-stack

mechanical design

• four (4) modules mounted on a rigid base plate
• four (4) guide bushings for pre-alignment
• two versions available:
  helix-e 30 with 30 kgf (294 N – total: 1176 N) contact force per module
  helix-e 150 with 150 kgf (1960 N – total: 5880 N) contact force per module
• maximum system stability
• compatibility with most common test head types used in the field
• simple and efficient installation
• installation without the need for an alignment jig for most applications

functional features

• adjustable z-stack, modules synced electrically
• individual z-position measurement on each module
• teach-in capability for z stop position
• parallel alignment relative to the handler
• fine adjustment of the docking stop position 
  while in the docked state (no undocking required)
• optional implementation of a mechanical hard stop
