Основные характеристики продукта

1. Absolute Measurement Principle: Directly read the current absolute angle once powered on without homing operations; position data is permanently stored after power failure to avoid re-homing after power-up.
2. High-Precision Optical Scanning: Mature optical detection technology paired with 18-bit high resolution delivers sub-arc-second repeatability to meet precision positioning demands of high-end equipment.
3. PROFINET Industrial Bus: Standard PROFINET IO interface directly compatible with mainstream PLC control systems such as Siemens, enabling high-speed real-time exchange of position and speed data.
4. Blind Hollow Shaft Design: The standard 15 mm bore fits most servo motor shafts; front clamping mounting eliminates extra couplings to save installation space and simplify commissioning.
5. Robust Environmental Adaptability: Wide-voltage power supply, high protection rating and wide temperature range enable stable long-term operation in harsh industrial environments with dust, moisture and strong electromagnetic interference.
6. Flexibly Configurable Parameters: Customizable parameters including preset position value, counting direction and speed sampling rate to fit application scenarios across diverse industries.

1. Key Notes for Replacement Selection
2. No Protocol Mismatch: The original model uses PROFINET; EtherCAT/SSI/EtherNet/IP encoders cannot be directly replaced
3. Core Mechanical Matching Mandatory: Confirm BH 15 mm blind hollow shaft structure; сплошной вал / through-hole shaft cannot be directly installed
4. Connector Wiring: Original unit equipped with dual D-coded M12 Ethernet ports; replacement models must feature built-in dual-port switches
5. PLC Programming: Original or replicated domestic models reuse existing GSD files; third-party brands require importing matching GSD files
6. Precision Matching: 18-кусочек (262,144) resolution is mandatory; 16-bit models lead to insufficient positioning accuracy
7. Selection Priority Recommendations
8. Zero commissioning, unlimited budget: AFS60A-BFNB262144 (direct same-series OEM replacement)
9. Multi-stroke travel required: AFM60A-BHNB018X12
10. Long-term mass cost reduction: Domestic GMX60-BH15-PN-18
11. Mid-budget imported equivalent: Pepperl+Fuchs RVI58N PROFINET Series
