Barksdale Control Division T-9048-5 Pressure Actuated Switch

The Barksdale Control Division T-9048-5 Pressure Actuated Switch is a sealed piston, SPDT snap-action device that monitors hydraulic or pneumatic pressure and automatically switches electrical control circuits when a preset pressure is reached. With an oil- and dust-tight NEMA 13 enclosure in anodized aluminum, it is designed for demanding industrial environments and uses a wetted 416 stainless steel piston with Buna-N O-Ring to ensure reliable operation across a wide pressure range. It accepts a 1/4"-18 NPT female pressure connection and a 1/2" NPS conduit with screw terminals, offers adjustable increasing range from 395 to 5,000 psi (26.9 to 345 bar) and decreasing range from 350 to 4,650 psi (23.8 to 316 bar), and provides 10 A at 125/250/480 VAC or 0.03 A at 250 VDC, with a proven 10,000 psi (690 bar) proof pressure. Typical applications include hydraulic presses, machine tools, compactors, compressors, hydraulic power units, and other industrial process controls; maintenance technicians and system integrators rely on this model for safety shutdown and pressure interlock functions, and it serves as a common replacement for Barksdale 9048-5, 9048-5-CS, and 9048-4.
