Industrial SOR 12N-AA5-N4-B1A Pressure Switch

Industrial SOR 12N-AA5-N4-B1A Pressure Switch is an industrial-grade sensing switch that monitors pressure in pneumatic and light hydraulic lines and triggers a control circuit when the setpoint is reached. It is specified for a sensing range of 0.75 to 12 psi and a 400 psi proof pressure rating, offering reliable operation in low-pressure applications. The part number’s N4-B1A designation signals a configured variant intended for industrial environments. SOR’s standard wetted-part construction for pressure switches is typically suitable for air, oil, and water service, making this model a practical choice for controlling pumps, compressors, and other process equipment in related applications.
