It uses a 1\/4\" NPT female pressure port and a NEMA 4 enclosure for reliable operation in damp or dusty environments, with wiring options that include free leads about 18 inches long (16 AWG) or a 3\/4\"-14 NPT conduit connection for flexible installation. Electrical ratings are 10 A at 125\/250 VAC and 3 A at 480 VAC, and the device employs SPDT contacts suitable for common control circuits; wetted parts consist of 304 stainless steel with a 17-7 PH stainless steel diaphragm. The pressure range spans 0.5 to 36.2 psi, with direction-dependent actuation thresholds (decreasing 0.5 to 34.6 psi; increasing 1.9 to 36 psi), making it appropriate for controlling fans, pumps, or alarms in pneumatic or hydraulic circuits. Ambient operating temperature extends from −65 to 165 F, enabling use across a broad range of industrial environments, and the unit measures roughly 4.5 in high by 4.0 in wide by 4.7 in deep, reflecting its compact, panel‑mountable housing.\u003c\/p\u003e\u003c\/div\u003e","brand":"Barksdale","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51676697854254,"sku":null,"price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_cd8e4475-76e3-49d5-96b0-9f61e1feffdb.jpg?v=1769552422","url":"https:\/\/plgautomation.com\/products\/barksdale-controls-cd1h-h2ss-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
