Measurement System
The ASML series linear optical encoder features a non-contact reflective photoelectric design with a highly corrosion-resistant stainless steel scale tape, delivering standard AquadB incremental square-wave signals. Equipped with internal interpolation circuitry and LED status indicators, it offers easy installation and debugging with stable, reliable operation. Widely used in high-precision linear displacement feedback applications such as linear motors, semiconductor processing, LED packaging, machine vision, precision metrology, and X-Y stages.

Installation Instructions
1. Grating ruler installation:Ensure the mounting surface is clean, dry, and free of oil. Use the dedicated fixture for installation; do not scratch the scale face with hard objects. After installation, clean the scale face with a lint-free cloth.
2. Install the reading head:Adjust the gap between the readhead and scale to 0.75mm until the green LED stays on; ensure the mounting bracket is rigid; do not touch the optical window with your hands.
3. Wiring Requirements:Use twisted-pair shielded cable with single-point reliable grounding. Do not connect or disconnect connectors while powered to prevent module damage from static electricity or surges.
4. Power-on debugging:Green light = Normal operation; Red light = Installation gap anomaly or signal fault, requires realignment.
5. Routine Maintenance:Clean the scale strip regularly with isopropyl alcohol or anhydrous ethanol. Check that mounting screws are tight. Avoid use in dusty, oily, or corrosive environments. Higher resolution requires a cleaner scale surface.
