New Diaphragm-Operated Pressure Switches for Tough Environments

May 31, 2017

Riverdale, NJ, May 31, 2017 – 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.
