Pressure Switch for Industrial Control
The Ashcroft B424VXCYLM200 is a diaphragm-actuated pressure switch designed for machinery and machine-shop applications. It provides a Standard action with a SPDT contact form to open or close circuits at the set point. The unit carries NEMA 13, 3, 4 and 4X ratings for use in demanding environments.
Sustained Operation and Switching Behaviour
The switch operates across a 20 to 200 psi range with a differential of 5 to 13 psi. Factory on/off setting is fixed at 90 percent of range. AC contact ratings are 15 A at 125 V, 15 A at 250 V and 15 A at 480 V. DC ratings are .25 A at 125 V, .5 A at 120 V and 6 A at 30 V.
Connection and Mounting Constraint
A single 1/4 in FNPT port connects the process media to the diaphragm. The housing conforms to NEMA 13, 3, 4 and 4X without additional enclosures. Buyers who need multiple ports or a different thread type cannot use this model.

Questions about this item
How much power does the Ashcroft B424VXCYLM200 draw when the contacts stay closed all day?
The switch itself draws no power; it only carries the load. AC contacts are rated 15 A at 125 V, 250 V or 480 V, and DC contacts 0.25 A at 125 V, 0.5 A at 120 V or 6 A at 30 V.
What wiring or fittings must I already have to install this pressure switch?
You need a 1/4 inch FNPT port on your system and wire sized for up to 15 A AC or the applicable DC rating. The switch has one 1/4 inch FNPT connection.
Will the SPDT contacts work with a 24 V DC relay coil from older equipment?
Yes. The DC rating allows 6 A at 30 V, so a typical 24 V coil well within that limit can be driven directly by the SPDT contacts.
