SMC Corporation ZSP1-S0X-15CN-D Vacuum Switch

The SMC ZSP1-S0X-15CN-D Vacuum Switch is a compact vacuum sensing unit that pairs a vacuum switch with adsorption confirmation capability, designed for monitoring the suction line in automated handling systems. It operates on 12–24 V DC with an NPN output, and senses vacuum in the range of -20 to -101 kPa, ensuring reliable detection across typical industrial suction scenarios. The nozzle orifice measures 0.5 mm, enabling precise response to changes in vacuum while minimizing flow impact on the system. The model designation S0X-15CN-D identifies the exact variant in the ZSP1 family. This device is used to confirm adsorption of a workpiece by a vacuum nozzle, providing a programmable, switch-triggered signal to PLCs and other control hardware to verify successful pick-up before proceeding with downstream operations. Typical applications include automated pick-and-place, packaging, material handling, and assembly lines where repeatable vacuum hold is critical. The compact form factor and single-switch output simplify integration into existing pneumatic manifolds and control circuits, delivering deterministic feedback for process control.
