SMC Corporation ZSE40-T1-62L Vacuum Switch

SMC ZSE40-T1-62L is a digital vacuum switch in the ZSE40 family that provides precise vacuum monitoring and a reliable electrical signal when the process crosses a user-set threshold. It runs on 12–24 VDC, drawing 55 mA or less, and offers NPN or PNP switching with up to 80 mA per output and a maximum output voltage of 30 VDC (residual voltage under load about 1 V). The device measures vacuum from 0 to -101.3 kPa (0 to -760 Torr) with a high insulation resistance specification around 50 MΩ to resist drift in harsh environments. The T1 variant uses an NPT 1/8 in process connection, and the 62L suffix identifies the specific variant configuration for this model. Applications include automation, robotics, packaging, and other pneumatics-driven systems where precise vacuum detection and dependable signaling are required. Some ZSE40 configurations also include a digital display for on‑machine vacuum readouts, improving visibility and diagnostics.
