Square D 9012GDW5 Pressure Switch 3-150 Psig Spdt-db

Product Description

The SQUARE D 9012GDW5 is an electromechanical pressure and level switch rated for 3 to 150 psig, designed for use in hydraulic and pneumatic control systems. It features a single-pole double-throw with double-break (SPDT-DB) contact form and a fixed differential pressure setting with a maximum differential of 6 psi. Voltage compatibility spans 120 VAC, 240 VAC, 125 VDC, and 250 VDC, making it adaptable across a range of control circuit configurations. Screw terminal connections simplify field wiring. Licensed electricians and industrial controls technicians are the primary installers of this switch in automated or manually controlled fluid-power systems.

The 9012GDW5 is suited for residential, commercial, and light industrial applications where reliable pressure sensing is required in hydraulic or pneumatic circuits. Its vibration-resistant construction allows installation in environments subject to mechanical vibration, such as compressor rooms, pump stations, or machine control panels. The fluid connection uses a 1/4 inch port and conduit entry is 1/2 inch, fitting standard control enclosure knockouts. NEMA 4, 4X, and 13 ratings make it appropriate for indoor and outdoor installations exposed to dust, oil, and washdown conditions.

Key Features

• Electromechanical SPDT-DB contact form for reliable switching in control circuits
• Operating range of 3 to 150 psig with fixed differential pressure
• NEMA 4, 4X, and 13 rated enclosure for dust-tight, oil-tight, and corrosion-resistant protection
• Vibration-resistant construction per IEC 68-2-6 and IEC 58-2-27
• Compatible with 120 VAC, 240 VAC, 125 VDC, and 250 VDC control circuits
• Meets CE, CSA C22.2 No. 14, UL 508, and RoHS compliance standards

Compatibility

Designed for use with hydraulic systems and pneumatic systems as stated by the manufacturer. The 1/4 inch fluid connection port and 1/2 inch conduit entry are standard fitments in industrial and commercial control panel applications.

Installation Notes

Installation should be performed by a qualified electrician or licensed controls technician in accordance with NEC requirements and applicable local codes. De-energize the control circuit and depressurize the system fully before making any connections or removing the existing switch. Use appropriately rated conduit fittings for the 1/2 inch conduit entry to maintain the NEMA enclosure rating. Do not exceed the rated pressure or voltage limits specified for this switch.
