The part number 21356A is consistently paired with the 11-3L designation in reseller catalogs and marketplace listings, confirming its place in HP\/Agilent’s legacy ultrasound portfolio that supported Philips’ Sonos systems. In multiple second‑hand marketplaces and catalogs, this transducer appears as the Philips\/Agilent 21356A 11-3L, reinforcing its identity within the Philips\/Agilent lineage and its intended compatibility with older Sonos consoles. The 11-3L\/21356A combination is repeatedly referenced when discussing components for maintenance, replacement, or service on the Sonos family of systems, reflecting its status as a legacy probe within that ecosystem. While detailed technical specifications are not always published in public catalogs, the repeated pairing of 21356A with 11-3L across listings provides a reliable fingerprint for this specific transducer in the Philips\/Agilent lineage.\u003c\/p\u003e\u003c\/div\u003e","brand":"Agilent","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657131360558,"sku":null,"price":362.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_94462970-dd99-49fd-b740-d62fd95713c5.jpg?v=1769466273","url":"https:\/\/plgautomation.com\/products\/agilent-technologies-21356a-ultrasound-transducer","provider":"PLG Automation ","version":"1.0","type":"link"}
