The Sor 4NN-K4-C pressure switch is an industrial sensing device that opens or closes an electrical circuit when process pressure reaches its set point, enabling automatic control in pneumatic and related systems. It is specified for a 1–25 psi range and uses a 1/4" NPT process connection for direct threading into standard piping or manifolds, a common configuration within SOR's 4NN family. This model's compact footprint and 1/4" NPT(F) port make it suitable for inline monitoring and interlock applications in equipment such as compressors and air lines where a fixed pressure threshold triggers a control action.
