3SF1324-1SD21-1BK4 Siemen Safety door lock Module

Overview

3SF1324-1SD21-1BK4 is a miniature 3/2-way normally closed pneumatic solenoid valve built for light-duty automated pneumatic actuation systems. Designed with single 24VDC electromagnetic coil and integrated high-performance rubber sealing components, this compact solenoid delivers rapid, consistent air channel switching for small air cylinders, clamping fixtures, air blow-off nozzles and micro pneumatic actuators.

Unlike large manifold-mounted industrial valves, the 3SF1324-1SD21-1BK4 adopts a slim monoblock aluminum alloy valve body that minimizes cabinet installation space. Its standard inline air port layout supports quick pipeline connection without complex manifold accessories, while the built-in anti-leakage sealing structure eliminates compressed air waste during long-cycle continuous operation. The 24VDC low-voltage coil meets global industrial safety standards, reducing electric shock risks on production lines. With excellent resistance to moderate workshop dust and dry compressed air media, 3SF1324-1SD21-1BK4 serves as a cost-effective pneumatic control component for new small automation machine development and aging miniature solenoid valve replacement projects.
