Schneider Electric 9012-ACW-6 Pressure Switch

Schneider Electric's Square D 9012-ACW-6 pressure switch is a pressure-sensing device that opens or closes electrical contacts when the sensed pressure crosses a setpoint, enabling automatic control for hydraulic and pneumatic systems. The 9012-ACW-6 family specifies a sensing range of 75–500 psi with a differential window of 50–120 psi and a 1NO/1NC contact arrangement, with a G1/4 pressure port. The 9012-ACW-6-M12 variant replaces the standard electrical termination with an M12 connector (Form M12) and is IP65-rated for rugged, moisture-resistant installation; the fluid port remains G1/4. Standard configurations of the 9012 series use a G1/4 pressure connection for the fluid path and a compact body suitable for panel mounting in industrial equipment. Schneider Electric's official literature, including the Square D 9012 data sheets and catalogs, provides the confirmed ranges, differential, and contact arrangements for the 9012-ACW-6 line.
