SMC ZSE4-T1-65 Pressure Switch

The SMC ZSE4-T1-65 is a digital vacuum pressure switch that provides a crisp binary signal when a preset negative-pressure level is reached in pneumatic systems. It operates from 12 to 24 VDC and features a PNP open-collector output rated to 80 mA, making it suitable for directly driving PLC inputs or relay coils. This vacuum-type switch is designed to monitor suction pressure, with a sensing capability that supports vacuum levels down to a maximum of -101 kPa, enabling reliable feedback for suction-based automation. Use cases include monitoring vacuum presence in robotic grippers, pick-and-place workflows, and packaging lines where timely vacuum on/off signaling is essential for proper hold and release actions. The ZSE4-T1-65 integrates into control circuits to provide consistent switching behavior under common industrial conditions, helping to optimize automation timing and prevent misfeeds or drops in vacuum-powered processes. In short, it’s a compact, dedicated vacuum sensor with a 12–24 VDC supply and a robust 80 mA PNP output designed for dependable vacuum status feedback in automated equipment.
