Ball screw motorized Z stages for fine vertical adjustment over 50–1000 mm of travel.

PAxx-Z stages are vertical versions of the PA series motorized linear stages, adding a right-angle mounting block and a power-failure protection unit for Z-direction use. Except for motion direction and load rating, the specifications match the standard PA stages. Nine models cover 50 to 1000 mm of travel using precision ball screws, linear slider guides and two-phase 57 stepping motors.

Key Features

  • Precision ball screws (φ12 × 4, φ16 × 5 or φ25 × 5) with linear slider guides
  • 1 µm (50–200 mm models) or 1.25 µm (300–1000 mm models) resolution at 20 microsteps
  • Repeatability ≤ ±3 µm up to 400 mm travel and ≤ ±5 µm for 600–1000 mm
  • Right-angle mounting block and power-failure protection unit for vertical operation
  • Centered vertical load of 15 kg (PA050-Z to PA400-Z) or 30 kg (PA600-Z to PA1000-Z)
  • Built-in limit (2) and origin (1) sensors; DB9 connector with 0.2 m high-flex cable
  • Ordering options include a 42-frame stepping motor, AC servo motors with mounting plates, and external sensors

Typical Applications

  • Fine Z-axis adjustment
  • Vertical positioning in automation and test equipment
  • Long-travel lifting of optics, cameras or samples
  • Height adjustment in optical setups
