Johnson Controls P233A-4-AAC Pressure Switch

Differential Pressure Switch, 0/5 Mbar to 4 Mbar Range, < 0.3 Mbar Differential, SPDT

Johnson Controls P233A-4-AAC Differential Pressure Switch – 0.5 to 4 mbar, SPDT, OEM Quality

The Johnson Controls P233A-4-AAC Differential Pressure Switch is an OEM-grade sensing device designed to detect subtle changes in airflow or pressure. With a pressure range of 0.5 mbar to 4 mbar and a differential sensitivity under 0.3 mbar, this SPDT switch offers precise performance for monitoring air or gas flow in HVAC systems and other industrial applications.

Engineered for accuracy and reliability, this switch responds to pressure changes across a diaphragm, actuating the switch as airflow fluctuates. It's an ideal choice for detecting small positive gauge pressures, vacuum conditions, or differential pressure across filters, fans, or air ducts.
