The SJ series was developed by SMC to offer a small, low profile, low maintenance, 4-port solenoid valve and manifold.? The series was designed in a cassette type format, uses a card-edge type connector, and is available in two compact sizes.? The SJ2000 measures 7.5mm wide, while the large SJ3000 model is only 10mm wide.? The SJ2000/3000 can be combined in the same manifold, which can provide up to 24 stations and 32 solenoids.? The valves feature a special lock switch mechanism assuring they are securely locked together, and are compatible with Serial Interface units for both CC-Link and DeviceNet protocols.
