SMC Corporation ZSE40A-N01-P-L Pressure Switch

The SMC ZSE40A-N01-P-L is a compact digital vacuum pressure switch from SMC’s ZSE40A/ISE40A family that combines sensing and switching in a single, self-contained unit. It monitors vacuum pressure and triggers its switch output when the programmed setpoint is reached, with adjustable hysteresis to minimize chatter in dynamic lines such as suction cup pick-and-place, packaging equipment, and robotics tooling. The device measures vacuum pressure from 0.00 to −14.69 psi (0 to −1.01 bar) and uses a two-color display to show the current pressure and the switch status at a glance, enabling quick verification during operation. The -N01-P-L configuration identifies a specific setup within the ZSE40A series, designed for reliable performance in compact footprints and straightforward integration with standard control circuits. This digital pressure switch provides a precise, easy-to-read indication of both pressure and switching condition, helping ensure consistent vacuum monitoring without needing separate sensors or extra electronics.
