| variant_note | ENRICHMENT-ONLY RECORD. ANMA already holds a full SG110CX specification record built from datasheet V1.21. No SG110CX datasheet was re-fetched in this session, so NO electrical value is asserted here - every electrical field is UNKNOWN by design and the existing ANMA record remains the source of truth for specifications. What this record adds is (a) documented accessory compatibility from the official 2026 Compatibility List and (b) an evidenced product-status/succession statement. |
