SOR SOR-K5-F1A-RR Pressure Switch

The SOR K5-F1A-RR pressure switch from SOR Inc. is a differential pressure switch with a 3 to 50 psi setpoint range and a 1/4 in NPT(F) pressure port. It is rated for up to 480 V AC and 15 A, enabling it to switch standard industrial power loads. As part of the K5 family, this model detects differential pressure and energizes a control circuit when the setpoint is reached, helping automate safety and efficiency in systems that require precise pressure monitoring. Typical applications include monitoring differential pressure across filters in HVAC or process lines, protecting pumps and compressors, and other process-control scenarios where reliable differential-pressure sensing is essential.
