Pressure Switch for Industrial Control
The Ashcroft LPDN4GGV25XCYLM200 is a differential pressure switch built for machinery and machine-shop applications. It uses a diaphragm actuation mechanism to open or close two SPDT contacts when system pressure crosses the set point. The unit carries NEMA 4 and 4X enclosure ratings for protection against water and dust ingress.
Factory-Set Differential Range 10 to 23 psi
The switch operates on an adjustable range of 20 to 200 psi with a fixed differential between 10 and 23 psi. Contacts are factory calibrated to actuate at 90 percent of the selected range. AC ratings are 15 A at 125 V, 250 V and 480 V; DC ratings are 0.5 A at 125 V and 250 V.
Mounts Via 1/4 in FNPT Port
A single 1/4 inch female NPT port connects the diaphragm to the process line. The DPST contact form provides two isolated switching poles for controlling separate circuits such as a motor starter and an alarm. The NEMA 4X housing allows installation in wash-down or outdoor environments without additional enclosures.

Questions about this item
What does the 20 to 200 psi range mean when the switch is installed?
The switch can be set to open or close anywhere between 20 and 200 psi, with a fixed differential of 10 to 23 psi between the on and off points.
How do the NEMA 4 and 4X ratings limit where this switch can be used?
The enclosure is rated for indoor or outdoor use, providing protection against windblown dust, rain, splashing water, hose-directed water, and corrosion.
What size fitting and thread type does the 1/4 in FNPT port require?
The port accepts a 1/4 inch male NPT pipe thread for a direct pressure connection.
