Ashcroft PDAN4HB25 Differential Pressure Switch

The Ashcroft PDAN4HB25 Differential Pressure Switch is a GP-Series, general‑purpose differential pressure switch built for tough industrial environments, delivering reliable setpoint switching in air and fluid systems. Housed in a NEMA 4X enclosure, it stands up to dust, water, and washdown conditions, making it suitable for ductwork, pumps, filtration, and process lines where differential pressure must trigger alarms or control equipment. The unit uses Ashcroft's GP-Series differential pressure sensing element and features adjustable deadband to fine‑tune the switching point to your application. Electrical contacts are rated for 10 A at 125/250 VAC, enabling direct integration with standard control relays and PLC inputs. This model embodies the GP-Series emphasis on rugged construction and configurability, offering a compact solution where a reliable differential pressure switch is required without sacrificing environmental protection or electrical versatility.
