Linear Scales
Linear Scales ABS ST700 SERIES 579 — General-purpose Type
• ABSOLUTE measurement with separate type scales • Non-contact detection is optimal for high speed and high acceleration devices such as linear motors • Electromagnetic induction principle means scales are unaffected by water and oil contamination • The detector head is approximately 1/3 the previous model size: 50 mm (W) × 28 mm (D) ×11 mm (H) • Cable outlets can be in four directions, with mounting holes on the top and sides • Compatible with servo amplifiers from a range of companies (high-speed serial interfaces)
