Ashcroft D464TXUD Pressure Switch

Ashcroft D464TXUD is a D-Series NEMA 4X differential pressure switch designed for reliable monitoring and control of differential pressure in harsh industrial environments, packaged in a watertight epoxy-coated aluminum enclosure rated for NEMA 4X and IP66. The unit offers adjustable setpoints from 15% to 100% of the selected range, with either fixed or limited adjustable deadband, and accepts a range of diaphragm materials—Buna-N, Viton, Teflon, 316L stainless steel, and Monel—to match process media and chemical compatibility. It covers pressure ranges from 30 inches of water differential up to 600 psid, with versatile pressure connections (1/4 NPT female with 1/2 NPT male combination or 1/4 NPT female with 1/2 NPT female) and standard ¾ NPT electrical termination, plus optional reduced-bushing configurations. Ambient operating temperature ranges from -20°F to 150°F (-29°C to 65°C), and retailer listings identify the D464TXUD as a discontinued Ashcroft pressure switch.
