SMC Corporation ZSE40-T1-22 Vacuum Switch

SMC ZSE40-T1-22 is a high-precision digital vacuum switch from the ZSE40/ISE40 family that provides both digital signaling and analog feedback for vacuum (or compound) pressure monitoring in automation equipment. This T1 variant uses a 1/8 in NPT port for threaded connections, aligning with the standard porting options in the series (01 and T1 encode R1/8 or NPT1/8 configurations). The unit offers two NPN open-collector outputs plus an analog output, enabling independent switch signaling and proportional pressure signaling for closed-loop control. Lead-wire lengths supported for this model include 0.6 m and 3 m to fit harnessing and panel-wiring needs, with the option for unit switching in certain configurations. Engineered for compact integration in pneumatic systems, it is well-suited for vacuum-handling applications, packaging lines, robotics grippers, and other automation tasks that require reliable vacuum threshold sensing along with real-time analog feedback. As part of SMC’s digital vacuum switch lineup, the ZSE40-T1-22 delivers quick response to pressure changes and a small footprint ideal for crowded control panels.
