Linear-encoder closed-loop Z stages for fine vertical adjustment over 50–1000 mm of travel.

The KAxx-Z series are vertical versions of the KA series motorized linear stages, fitted with a right-angle mounting block and a power-failure protection unit so the carriage can be driven in the Z direction. Apart from motion direction and load rating, the specifications follow the standard KA stages. A linear optical encoder closes the position loop at 1 µm resolution (KA050-Z to KA400-Z) or 0.5 µm (KA600-Z to KA1000-Z).

Key Features

  • Closed-loop control with a linear optical encoder: 1 µm or 0.5 µm resolution depending on model
  • Precision ball screws (φ12 × 4, φ16 × 5 or φ25 × 5) with linear slider guides
  • Right-angle mounting block and power-failure protection unit for vertical operation
  • Open-loop repeatability ≤ ±3 µm up to 400 mm travel and ≤ ±5 µm for 600–1000 mm
  • Centered vertical load of 15 kg (KA050-Z to KA400-Z) or 30 kg (KA600-Z to KA1000-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 (50–400 mm models), AC servo motors, right-side encoder mounting and external sensors

Typical Applications

  • Fine Z-axis adjustment
  • Vertical positioning in automated inspection and assembly
  • Long-travel lifting of optics, cameras or samples
  • Metrology and alignment setups
