Product Overview
MONORAIL AMS 3B is a high-precision roller linear guideway with integrated magneto-resistive measuring system. Position measurement functionality is directly integrated into the guideway system, eliminating the need for external optical or magnetic scales, simplifying mechanical design and improving system reliability.
System Features
- Integrated Guidance and Measurement - Guideway and measuring system combined, no external linear encoder required
- Roller Guidance Technology - MR series roller guideway technology for high rigidity and load capacity
- Magneto-Resistive Measuring Principle - Contamination resistant, maintenance-free, suitable for harsh environments
- Incremental Output - Provides 1 Vpp analog or TTL/RS422 digital signals
- High Resolution - Basic signal period 200 μm, subdivides to sub-micron level
- Reference Mark - Built-in reference marks for homing
