Description

The Ashcroft B424B is a robust, snap-action pressure switch designed for industrial applications requiring precise control of low-pressure differentials. It features a Buna-N diaphragm and steel wetted parts, making it suitable for use with air, non-corrosive gases, and compatible liquids. Key benefits include high reliability, adjustable setpoints, and a compact design that withstands harsh environments with NEMA 4X enclosure protection. It offers a pressure range of -15 to 15 inches of water (inH2O), with a proof pressure of 20 psi and a deadband of 1.2 to 1.5 inH2O, ensuring minimal hysteresis for accurate switching. Advantages over similar products include UL and CSA certifications for safety, vibration resistance, and easy installation. Commonly used in HVAC systems, vacuum pumps, and process control to monitor and control pressure thresholds. Drawbacks may include limited compatibility with corrosive media and the need for periodic calibration in high-vibration settings. This model excels in applications demanding low-pressure sensitivity and electrical ratings up to 15A at 480VAC.
