Fewer than 30% of Google searches for this category use words matching AI’s description of it. If you own this category, buyers may not find what AI says about you. Open the category — the five-vantage panel shows AI’s words and buyers’ words side by side.
These are the brands AI most associates with this electronics category.
You’re viewing a broad category. AI vocabulary is loose here, so non-component entities may appear in the ranking. Cleaner signal often appears one level deeper.
Showing 34 brands AI ranks as component manufacturers. The other 10 of 44 brands AI mentions in this category appear as distributors or category-surface entities (paid evidence layer).
Share is each brand’s portion of AI’s total mentions for this category. Mention counts are cumulative across the consensus panel and tracking weeks. Not normalized for panel turnover or model outages — cross-category comparisons require the evidence layer.
VERIFIED = the brand’s own product catalog lists this category · AI-DISPUTED = AI places it here but its catalog does not · UNCONFIRMED = no own-catalog evidence captured yet. We publish what AI says and whether it checks out — we never fabricate a placement. Click a brand for its full footprint.
Threshold rule, panel breadth, observed week, and the per-brand statistics behind each row — plus the reality checks (vantage alignment, supply geography, buyer vocabulary) that tell you whether AI’s rank for Pir Sensors holds up off-screen.
Open the evidence layer →How AI talks about Pir Sensors, compared to how OEMs describe it on their own product pages, how buyers search for it, how distributors bucket it, and how aggregators classify it in their taxonomies. Each of those five viewpoints is a vantage. The cosine between each pair of vantages tells you whose vocabulary tracks whose — 1.0 means identical wording, near 0 means they don’t share a vocabulary at all.
OEM self-description and Buyer search use the most-different vocabulary for this category — cosine 0.66.
