Control Circuit Rated Type G Pressure Switches
9012GAW5
NEMA 4, 4X, 13
Class 9012 single stage pressure switches are control circuit rated devices used in pneumatic or hydraulic systems on a wide variety of machine
and process applications to protect the equipment and control or monitor the system pressure.
•
Type G machine tool switches are available with NEMA Type 4, 4X, and 13 (IEC IP66) enclosure ratings.
•
The NEMA 7 and 9 devices are UL listed for use in the following hazardous locations: Class I, Divisions 1 and 2, Groups C and D; and Class II,
Divisions 1 and 2, Groups E, F, and G.
•
Enclosure materials are cast aluminum.
•
To ensure repeatability and minimize setting drift, pressure settings should fall within the middle 80 percent of the pressure range.

[5] For metric threads, add M after the W on all types (offered at an additional cost).
To order a Pg13.5 electrical conduit entry and a 1/4”-19 BSP pressure connection, add M12 to the end of the catalog number, as well as adding “M” after “W” for metric threads. For example:
9012GAW1 = 1/2” NPT electrical conduit entry
9012GAWM1 = 20 x 1.5 mm electrical conduit entry
9012GAWM1M12 = Pg13.5 electrical conduit entry and 1/4-19 BSP pressure connection.
[6] The differential adds to the range setting and determines the operating point on rising pressure.
