SMC Corporation SYJA7120-01 Pneumatic Solenoid Valve

SMC SYJA7120-01 is a 2-position, 5/2-way air-pilot solenoid valve from the SYJA7000 family, designed to direct compressed air to a double-acting actuator when energized and vent the opposite port when de-energized. The -01 variant is monostable (single solenoid with spring return) and features Rc 1/8 end-style connections for both pilot and main ports, aligning with standard 1/8 in Rc fittings. It is built to operate with supply pressures from 0.15 to 0.7 MPa, making it suitable for typical factory air systems and automated equipment. This model is commonly listed as “Solenoid Valve In Bag” in some catalogs, reflecting its packaging configuration, while still delivering the consistent performance expected from SMC’s SYJA7000-series valves. Applications span industrial automation tasks that require reliable on/off control of air to cylinders and actuators, including conveyors, pick-and-place machines, and assembly lines, where a compact, electrically actuated air-control solution is advantageous. The SYJA7000 family is recognized for its compact footprint and compatibility with standard pneumatic circuits, enabling straightforward integration into modular manifolds and existing piping layouts. Overall, SYJA7120-01 provides precise, repeatable valve action with a proven 5/2 function, suitable for medium-pressure pneumatic systems and automation environments that demand dependable actuation with minimal footprint.
