Commonly installed in conveyor systems, material handling equipment, packaging machinery, steel processing lines, and automated production systems requiring long-range metal detection and reliable position feedback. Maintenance teams and system integrators use this part for sensor replacement, machine retrofits, automation upgrades, and OEM equipment repairs. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"665\" data-end=\"682\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"683\" data-end=\"1275\"\u003eThe TURCK NI20-K40SR-VP4X2 is designed for demanding industrial proximity sensing applications where long sensing distances and reliable operation in harsh environments are required. It is frequently used in pallet conveyors, transfer stations, machine tools, heavy manufacturing equipment, and automated assembly lines where conventional barrel sensors cannot provide adequate sensing range. Its smooth Ø40 mm cylindrical housing and dual cable entry design simplify installation while the complementary PNP outputs provide flexible control integration.\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1277\" data-end=\"1306\" class=\"PDq2pG_selectionAnchorContainer\"\u003eTechnical Specifications:\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp data-start=\"1307\" data-end=\"2360\" class=\"\"\u003e• Manufacturer: TURCK\u003cbr data-start=\"1328\" data-end=\"1331\"\u003e• Model \/ Part Number: NI20-K40SR-VP4X2\u003cbr data-start=\"1370\" data-end=\"1373\"\u003e• Product Type: Proximity Switch \/ Inductive Sensor\u003cbr data-start=\"1457\" data-end=\"1460\"\u003e• Sensor Type: Non-embeddable Inductive Proximity Sensor\u003cbr data-start=\"1516\" data-end=\"1519\"\u003e• Housing Style: Smooth Cylindrical Barrel\u003cbr data-start=\"1561\" data-end=\"1564\"\u003e• Housing Diameter: Ø40 mm\u003cbr data-start=\"1590\" data-end=\"1593\"\u003e• Housing Length: 90 mm\u003cbr data-start=\"1616\" data-end=\"1619\"\u003e• Sensing Distance: 20 mm nominal\u003cbr data-start=\"1652\" data-end=\"1655\"\u003e• Output Type: PNP transistor output\u003cbr data-start=\"1691\" data-end=\"1694\"\u003e• Output Function: Complementary (NO + NC)\u003cbr data-start=\"1736\" data-end=\"1739\"\u003e• Supply Voltage: 10-65 VDC\u003cbr data-start=\"1766\" data-end=\"1769\"\u003e• Rated Load Current: 200 mA maximum\u003cbr data-start=\"1805\" data-end=\"1808\"\u003e• Switching Frequency: 100 Hz\u003cbr data-start=\"1837\" data-end=\"1840\"\u003e• Connection Type: Terminal chamber with axial and radial cable entries\u003cbr data-start=\"1911\" data-end=\"1914\"\u003e• Mounting: Non-flush installation\u003cbr data-start=\"1948\" data-end=\"1951\"\u003e• Housing Material: ABS plastic\u003cbr data-start=\"1982\" data-end=\"1985\"\u003e• Protection Rating: IP67\u003cbr data-start=\"2010\" data-end=\"2013\"\u003e• Operating Temperature: -25°C to +70°C\u003cbr data-start=\"2052\" data-end=\"2055\"\u003e• Status Indicators: Dual LED indicators\u003cbr data-start=\"2095\" data-end=\"2098\"\u003e• Special Features: Two cable entries, short-circuit protection, reverse polarity protection, extended sensing distance\u003cbr data-start=\"2217\" data-end=\"2220\"\u003e• Application: Metal object detection, machine positioning, and industrial automation control systems. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2362\" data-end=\"2386\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2387\" data-end=\"2517\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• TURCK \u003ca href=\"https:\/\/plgautomation.com\/products\/turck-ni20-cp40-vp4x2-b1141-inductive-sensor?_pos=1\u0026amp;_sid=27273cb6d\u0026amp;_ss=r\"\u003eNI20-CP40-VP4X2-B1141\u003c\/a\u003e\u003cbr data-start=\"2416\" data-end=\"2419\"\u003e• TURCK \u003ca href=\"https:\/\/plgautomation.com\/products\/turck-ni20-ck40-ap6x2-h1141-inductive-sensor?_pos=1\u0026amp;_sid=6f6a9fa3a\u0026amp;_ss=r\"\u003eNI20-CK40-AP6X2-H1141\u003c\/a\u003e\u003cbr data-start=\"2448\" data-end=\"2451\"\u003e• TURCK BI20-CP40-VP4X2\/S10\u003c\/p\u003e","brand":"Turck","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51714298806574,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_aca8a1f5-dd35-41ea-96ea-cdefb4eff1df.jpg?v=1770421887","url":"https:\/\/plgautomation.com\/products\/turck-ni20-k40sr-vp4x2-inductive-proximity-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
