Barksdale A9675-0-AA is a Series 9675 sealed-piston pressure switch designed to monitor and switch at a fixed pressure in the 20–200 psi range. The unit is a housed, mechanical switch that uses a piston sensing element and delivers SPDT electrical output with a 1/4 in connection size for mounting and plumbing. It carries a 10 A electrical rating and operates across a temperature range of -20 to 165 °F, making it suitable for industrial pneumatic and combustion-control applications where a 20–200 psi threshold is required.
