SMC Corporation ZSE40A-N01-T Digital Pressure Sensor

The SMC ZSE40A-N01-T is a compact, high‑precision digital pressure switch with a two‑color display, designed for vacuum and low‑to‑moderate pressure monitoring in pneumatic and automation systems. It operates from a 12–24 V DC supply with ±10% tolerance and polarity protection, drawing up to 45 mA. The device provides a digital readout of pressure (range commonly listed as −100 to 100 kPa in the ZSE40A family) for quick verification in line or bench setups. Port configurations cover a range of common connections, including standard 1/8 in. pipe/tube options (R1/8, NPT1/8, Rc1/8, G1/8) and threaded variants such as M5, with weights that vary by configuration (approximately 78 g for basic 01 port to about 97 g for larger head/lead options). The unit is specified for operating temperatures from −5 to 50°C, making it suitable for factory floors, machine tools, and packaging equipment where stable, readable pressure indication is needed. Built for real‑time monitoring, the ZSE40A family supports a stable digital display coupled with switching functionality, enabling straightforward integration into control schemes where vacuum or low‑pressure thresholds must be observed and acted upon. Applications include vacuum cups and manifolds in automation lines, quality‑control sampling points in pneumatic circuits, and general process monitoring where precise, on‑device pressure indication is critical.
