STP10 Adjustable Mechanical Pressure Switch

The STP10 series mechanical pressure switch uses a diaphragm or piston sensing element to convert pressure changes into fast and reliable contact switching control. The switch setpoint is adjustable, covering a wide range from 0.2 to 420 bar, suitable for water, oil, and gas media. It features a stainless-steel housing with IP65 protection, ensuring stable operation in harsh industrial environments with high or low temperatures. The internal changeover contact design provides fast response, high precision, and long-term stability. Multiple process connections (G1/4, G1/2, NPT, etc.) and DIN43650 electrical interfaces are available for flexible installation. Widely used in rail braking systems, wind power hydraulics, construction machinery, presses, medical equipment, and semiconductor equipment, the STP10 is an ideal solution for reliable pressure monitoring and safety control.
