The model designation is RDCA-4A-4M-C-HN, and the hyphen-free form RDCA4A4MCHN is commonly used for ordering. This device is part of PDI's RDCA family, a line of industrial sensing instruments designed to monitor pressure and provide precise actuation in control circuits. It is suitable for applications where an electrical signal must be generated in response to a specific pressure level, enabling automatic control, interlocks, or safety shutoffs within pneumatic or hydraulic systems. To ensure proper integration, verify that the exact model matches your system's interface and electrical connections, and consult formal specifications for the required pressure range and mounting options from the manufacturer or authorized distributors. Because this is an PDI device, compatibility with industry-standard connectors and mounting patterns is typically expected, and formal documentation should be consulted for definitive specifications, electrical ratings, and installation guidance.\u003c\/p\u003e\u003c\/div\u003e","brand":"PDI","offers":[{"title":"New","offer_id":51707479097646,"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_ff29dc08-5e73-4454-9ff6-b1bdb6065e25.jpg?v=1770230621","url":"https:\/\/plgautomation.com\/products\/pdi-rdca-4a-4m-c-hn-pressure-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
