LF20-H High Pressure Switch (10~400 PSI)

The LF20-H high pressure switches are robust, compact and designed to operate in harsh environments at various pressures. Because of its special internal design this high pressure switch can tolerate high pressure spikes inherent on many pressure systems. The switch is factory calibrated but in the case that adjustment is needed in the field the switch offers an adjustment screw to facilitate any fine tuning required. The standard diaphragm employed is polyimide making it compatible with many gases and liquids. Several other diaphragm materials are available that make the high pressure switch compatible with many mediums. Various electrical terminations are available including tabs and a metric-pack connector that forms a tight seal when connected. Because of their ruggedness the LF20-H is a popular choice for the many OEM applications.
