For operation in tough environments, Sigma-Netics Inc. has added two diaphragm-operated options to its portfolio of ruggedized pressure switches. Similar products were only previously available in piston-based operations.
The new 745 and 785 series of pressure switches are designed for low-pressure, high-sensitivity applications, including off-road or industrial OEM equipment, train braking systems, compactors, compressors and fuel systems. For maximum environmental protection, the 785 model is equipped with a 2- or 3-pin Deutsch connector.
Compliant with IP67 standards, both models have a temperature range of –40 to 250°F and are designed to thrive in tough environments containing oil, fuel, water, dust, vibration or shock. Custom configurations are available.
They are rated for pressures of 8 to 125 psig, with a maximum system pressure of 1,500 psig.
