Similar to many applications, when a pressure sensing switch is required, there can be several factors that determine if a particular switch meets all the required design criteria. The right pressure range, environmental ruggedness and long life could be initial requirements. In some instances, something as seemingly simple as the connector can be a knockout factor. For those applications where the 3-pin Deutsch connector on its 784 Series may have been incompatible possible because of space limitations, Sigma-Netics Inc. added a 2-pin Deutsch connector option. With an 8 to 6,000 psig range, -40 to 250°F temperature range, 303 stainless steel hydraulic module housing and other attributes, the new connector could be desirable addition for many applications.
