Contact Form

Refers to the number and type of contacts a device has for controlling connections.

1NO/1NC indicates the device has a normally open (NO) contact and a normally closed (NC) contact. NO contacts close circuits when energized. NC contacts open circuits when energized.
SPDT-1NO/1NC this represents a single-pole, double-throw switch. They have one normally open (NO) contact and one normally closed (NC) contact. NO contacts close circuits when energized. NC contacts open circuits when energized.
DPST this represents a double-pole, single-throw switch. They control one circuit and have contacts that are normally open (NO) or normally closed (NC).
DPDT this represents a double-pole, double-throw switch. They control two circuits and have changeover contacts.

Number of Pressure Connection Ports

This represents the number of pressure connection ports that a device has. These ports are openings on pressure switches to monitor fluid or gas pressure levels.

Pressure Connection Type

This represents the port type where the pressure source connects with the device. FNPT represents female-threaded connections, MNPT represents male-threaded connections, FNPS represents straight (non-tapered) female connections, and NPSF represents straight (non-tapered) male connections. The numerical values in parentheses represent the number of pressure connections a device has.

1/2" NPT
1/4-18" FNPT
1/4-18" MNPT
1/4-18" NPTF

Differential Pressure - Minimum

This refers to the minimum value of the differential pressure change which the gauge can measure between two locations in a hydraulic or pneumatic system.

0.64 psi
0.83 psi
2.46 psi

Differential Pressure - Maximum

This refers to the maximum value of the differential pressure change which the gauge can measure between two locations in a hydraulic or pneumatic system.

3.63 psi
4.42 psi
4.91 psi
9.82 psi

NEMA Enclosure Rating

1 is a safety rating for indoor electrical enclosures with nongasketed doors that specifies a degree of protection against incidental contact and the entry of solid objects such as falling dirt.
4 is a safety rating for indoor and outdoor electrical enclosures with gasketed doors that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (snow, rain, water splashes and sprays), against occasional washdowns, and against exterior ice formation.
4X is a safety rating for indoor and outdoor electrical enclosures – also known as washdown enclosures – that specifies a degree of protection against incidental contact, against the entry of solid objects (falling dirt, windblown dust) or water (rain, snow, water splashes and sprays), against corrosion, and against exterior ice formation.
13 is a safety rating for indoor electrical enclosures – often called oil-proof or oil-tight – that specifies a degree of protection against incidental contact and against the entry of solid objects (falling dirt, circulating dust), water (drips, light splashes), and oil or noncorrosive coolants (sprays, splashes, seepage).
