SMC Corporation ZSE1-T1-55C Pressure Switch

SMC ZSE1-T1-55C is a compact vacuum pressure switch that monitors a vacuum range from 0 to −101 kPa and translates that threshold into a reliable PNP open-collector signal for industrial automation. It operates from a 12 to 24 VDC supply (±10%, ripple ≤10%, with power-supply polarity protection) and provides a single PNP output (30 V max, 80 mA or less) for fast, clean switching, with a response time of 5 ms or faster. The sensor offers ±1% full-scale repeatability and is built to an IP40 enclosure with an operating temperature range of 0 to 60°C and 35 to 85% RH (non-condensing). Typical port size is 1/8 in, and the unit weighs about 40 g including a 0.6 m lead wire; mounting options include ZM ejector mounting or the T1/01/00 port configurations described in the ZSE1 family. Designed for vacuum sensing in automation, packaging lines, robotics, and process control, the ZSE1-T1-55C delivers a precise vacuum threshold suitable for triggering PLCs or other logic without relying on analog pressure measurement.
