Square D 9012GDW2 Pressure Switch 1-40 Psig Spdt-db

Product Description

The SQUARE D 9012GDW2 is an electromechanical pressure and level switch rated for 1 to 40 psig with a fixed differential pressure setting. It uses an SPDT-DB contact form with screw terminal connections and is designed for reliable operation in demanding hydraulic and pneumatic control circuits. The switch handles multiple voltage ratings including 120 VAC, 240 VAC, 125 VDC, and 250 VDC at 6 amps. Its vibration-resistant construction and NEMA 4, 4X, and 13 enclosure ratings make it suitable for wet, dusty, and wash-down environments common in industrial and mechanical system installations.

This pressure switch is intended for use in hydraulic systems and pneumatic systems where fixed differential control is required. The 1/4-inch fluid connection port and 1/2-inch conduit connector make it straightforward to integrate into existing process piping and control panel wiring. Licensed electricians and instrumentation technicians typically install this switch as part of automated pressure monitoring, machine safety interlocks, or fluid system controls in commercial and light industrial applications.

Key Features

• 1 to 40 psig operating pressure range with fixed differential pressure
• Maximum differential pressure of 0.6 psi for precise switching
• SPDT-DB contact form supports dual-circuit switching configurations
• NEMA 4, 4X, and 13 ratings provide protection against water, oil, and corrosion
• Vibration-resistant design for use in high-vibration environments
• Multiple voltage compatibility: 120 VAC, 240 VAC, 125 VDC, 250 VDC
• Meets CE, CSA C22.2 No. 14, IEC 68-2-6, UL 508, and RoHS requirements

Compatibility

Designed for use with hydraulic systems and pneumatic systems requiring electromechanical pressure switching with fixed differential control.

Installation Notes

Installation should be performed by a licensed electrician or qualified instrumentation technician in accordance with NEC requirements for control circuit wiring. De-energize and depressurize the system fully before connecting or disconnecting the switch. Use the 1/2-inch conduit entry for proper wiring ingress and maintain the appropriate NEMA enclosure rating by sealing all unused conduit entries. Verify that system operating pressure does not exceed the 40 psig rated maximum during normal or transient conditions.
