Description

The Barksdale 9048-2 is a sealed piston mechanical pressure switch in the Series 9048 family. It is designed for hydraulic and pneumatic systems requiring reliable setpoint switching across a wide adjustable pressure range. Refer to manufacturer documentation to confirm compatibility with your specific application.

The 9048-2 features a Single Pole, Double Throw (SPDT) snap-action contact with an adjustable increasing pressure range of Sixty to Five Hundred (60–500) PSI and a decreasing pressure range of 50–460 PSI, with a switch accuracy of ±2% of the adjustable range. The electrical rating is 10A at 125/250/480 VAC and 0.03A at 250 VDC. The pressure port is a 1/4"-18 NPT female connection, and the sensing element consists of a 440 stainless steel piston with a Buna-N O-ring seal.

The anodized aluminum enclosure includes an integrated 1/2" NPS conduit connector for wiring entry and a tamper-resistant setpoint adjustment screw. The unit is rated NEMA 13 (oil and dust tight) as standard and is rated for operation from -40 to 165°F (-40 to 74°C).
