Asco Numatics SA11AG Pressure Switch

ASCO Numatics SA11AG Pressure Switch is a Tri-Point pressure switch that provides a discrete electrical signal whenever the monitored pressure crosses a programmed setpoint. This SA11AG unit belongs to ASCO’s Tri-Point line, which uses a Tri-Point alternating fulcrum balance plate design to deliver stable, repeatable actuation in industrial control loops. The switch is intended for monitoring hydraulic or pneumatic pressures in automation systems and is commonly used to interlock compressors and regulators, trigger control logic, or serve as a safety or alarm interface when pressure crosses the threshold. Exact specifications—such as the setpoint range, electrical output type, port sizes, and wetted-material compatibility—vary by configuration, so consult the official ASCO Numatics SA11AG datasheet or product page for the precise values that apply to your installation. Emerson, the parent company, markets ASCO Numatics pressure and temperature switches, and SA11AG is part of that legacy portfolio.
