The loop should be routed in such a way that it encloses the intended usable area. The power requirement depends on the area of the reception field, its nature and the type of loop installation. As a guideline, 0.1W\/m² can be assumed, whereby in reinforced concrete buildings the requirement can increase to approx. 0.3-1W\/m². The temporary installation of a test loop provides information on this, as well as on possible interference. For large areas, subdivision into sub-areas is useful. When using the ST 50 (G), the impedance of the loop should be between 0.5 and 2 ohms. It corresponds approximately to the DC resistance. When using multi-core cables, the resistance can be adjusted by parallel or series connection of the individual cores. To be able to optimally adjust the loop field, a separate power amplifier is recommended.\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan face=\"Lato-Regular\"\u003e\u003cspan face=\"Lato-Regular\"\u003eST 50: Incl. two brackets for mounting in a housing.\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan face=\"Lato-Regular\"\u003e\u003cspan face=\"Lato-Regular\"\u003eST 50 G: Built into a plastic housing, incl. multi-pole terminal strips.\u003c\/span\u003e\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical data sheet: \u003ca title=\"WHD-ST_50-Uebertrager-Datenblatt.jpg\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2411\/7471\/files\/WHD-ST_50-Uebertrager-Datenblatt.jpg?v=1695198180\" target=\"_blank\"\u003eDownload\u003c\/a\u003e (DE), \u003ca title=\"WHD-ST_50-Transformer-Datasheet.jpg\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2411\/7471\/files\/WHD-ST_50-Transformer-Datasheet.jpg?v=1695198180\" target=\"_blank\"\u003eDownload\u003c\/a\u003e (EN)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOperating instructions: \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2411\/7471\/files\/WHD-ST50-Schleifenuebertrager-Transformer-Bedienungsanleitung-Manual.PDF?v=1695198562\" target=\"_blank\" title=\"WHD-ST50-Schleifenuebertrager-Transformer-Bedienungsanleitung-Manual.PDF\" rel=\"noopener noreferrer\"\u003eDownload\u003c\/a\u003e (DE\/EN)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e \u003c\/p\u003e","brand":"2-3 Tage","offers":[{"title":"Default Title","offer_id":32193433501809,"sku":"125-605-00-100-00","price":259.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2411\/7471\/files\/ST50_WEBSEITE.png?v=1721034098","url":"https:\/\/whd.de\/en\/products\/st-50","provider":"WHD.de","version":"1.0","type":"link"}
