ADSEN AP40V-04-F2-QD Pressure Switch AP40V-04-F2-QD

ADSENS AP40V-04-F2-QD is a compact vacuum pressure switch designed to monitor negative pressure in pneumatic and automation systems. It operates on 12–24 VDC and provides a switch output suitable for signaling when the vacuum level crosses a configured threshold. The F2 variant specifies a pressure port with a 1/8" NPT thread for easy, secure installation, while the QD designation indicates a quick-disconnect electrical connection for fast wiring. The device covers a vacuum range from -101.3 kPa to 0 kPa (full vacuum to ambient), enabling reliable detection across typical industrial vacuum applications. Electrical load capability is specified up to 125 mA, supporting simple digital or logic-level signaling without heavy power draws. Typical applications include monitoring and controlling vacuum conditions in pneumatic tooling, packaging lines, conveyor systems, and process automation where a clear, repeatable vacuum signal is required. This ADSENS component is part of a family of precision pressure switches known for straightforward installation, robust port options, and compatible electrical interfaces, making it a practical drop-in for systems that require a dependable vacuum switch with a compact form factor.
