It is particularly suited to liquids in industrial equipment, cooling and lubrication.\u003c\/p\u003e\u003cp\u003eA magnetic piston on a spring is displaced by the flow, and the magnet closes a reed contact outside the wetted part. Setting range in seven sizes from \u003cstrong\u003e2 … 9\u003c\/strong\u003e to \u003cstrong\u003e50 … 200 L\/min\u003c\/strong\u003e, switching point set on an engraved scale calibrated in water at 20 °C with horizontal mounting. Accuracy ± 5 of the total range, for which the datasheet gives no unit. Hysteresis depends on the switching point, at least 0.6 L\/min. Output \u003cstrong\u003ereed contact, one changeover\u003c\/strong\u003e, switching capacity \u003cstrong\u003e24 V DC \/ 1 A\u003c\/strong\u003e. The datasheet names no supply voltage. Connection M12 connector or rectangular plug.\u003c\/p\u003e\u003cp\u003eBody and piston in nickel-plated brass, spring stainless steel, seal NBR. Process connection female thread G or R from 1\/2 to 1½ inch by size.

A declaration of conformity is not documented in the datasheet. Before sizing, note: An ambient temperature is not documented. Mounting position, medium and temperature shift the switching value, and the datasheet does not say by how much. The accuracy figure ± 5 is given without a unit.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMechanical principle with reed contact outside the medium\u003c\/li\u003e\u003cli\u003eMechanical and electrical parts completely separated\u003c\/li\u003e\u003cli\u003eSeven sizes up to 200 L\/min\u003c\/li\u003e\u003cli\u003eEngraved setting scale, no flow rig needed\u003c\/li\u003e\u003cli\u003ePressure rating 100 bar\u003c\/li\u003e\u003cli\u003eMedium temperature up to 90 °C\u003c\/li\u003e\u003cli\u003eChangeover contact 24 V DC \/ 1 A\u003c\/li\u003e\u003cli\u003eProtection IP67 with M12 connector\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453604897094,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKH_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qskh-piston-flow-switch-nickel-plated-brass","provider":"octogon GmbH","version":"1.0","type":"link"}
