It provides an adjustable setpoint from 3 to 50 psi with an over-range capability of 750 psi, enabling reliable on\/off control in process and safety interlocks. The switch uses a 1\/4\" NPT(F) pressure port and comes in a durable aluminum B1A housing rated for NEMA 4X\/IP65 environments, making it suitable for damp, dusty, or washdown‑friendly areas. The -X variant belongs to the 4NN family and maintains the same core switching performance while fitting compact installations common in turbine spare parts and industrial facilities. Typical applications include activating a secondary valve or pump once the process pressure crosses the setpoint, providing a fail-safe signal in automated control schemes, and serving as a simple pressure limit switch in pneumatic systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"SOR","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51712658440494,"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_329ea59a-c327-43dd-9362-117e74b7471b.jpg?v=1770360690","url":"https:\/\/plgautomation.com\/products\/sor-4nn-k5-n4-b1a-x-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
