China Flush - mount door lock kit for switchgear Manufacturer, Supplier, Factory

The Switchgear M12 Shaft is a precision-engineered component designed to enhance the functionality and reliability of electrical switchgear systems. This shaft is characterized by its M12 threading, which ensures a secure and stable connection in a variety of switchgear assemblies. Manufactured from high-grade stainless steel or durable alloy materials, it offers exceptional resistance to corrosion, wear, and mechanical stress, making it ideal for demanding industrial environments.

Switchgear busbar supports are essential components designed to provide robust structural support for busbars in electrical switchgear systems. Constructed from high-strength materials such as steel or aluminum, these supports ensure excellent mechanical stability while minimizing electrical resistance. They facilitate the secure mounting of busbars, allowing for efficient current distribution throughout the system.

SOLH 4H series hand lever directional control valves are developed in accordance with mainstream industrial standards, covering 5/2-position and 5/3-position configurations. Operated purely by manual lever manipulation without electromagnetic coils or pneumatic pilot signals, these spool-type manual valves are widely adopted for on-site equipment commissioning, emergency safety shutdown and inching control of double-acting cylinders. Constructed with high-strength aluminum alloy housings and precision spool assemblies, two positioning structures are optional: automatic spring return and steel ball mechanical locking. Crucially, the mounting dimensions are fully consistent with 4V solenoid valves and 4A air-operated valves, enabling direct interchange and flexible switching among electric, pneumatic and manual control modes in standard pneumatic systems. The five-port layout complies with international general specifications: P serves as the main compressed air supply inlet; Ports A and B connect to two cavities of double-acting cylinders to govern extension and retraction movements; R and S are exhaust ports compatible with standard silencers to lower exhaust noise. For 5/2-position models, spring-reset variants automatically rebound once the lever is released to deliver foolproof protection against unintended continuous actions; self-locking versions secure the spool position via steel ball positioning and stay latched until manual switching, ideal for long-duration fixed working states. All 5/3-position units adopt dual stable ball positioning with three configurable neutral modes. Closed Center (Type C) seals all ports to lock cylinders and prevent falling of vertically mounted actuators; Exhaust Center (Type C) vents A/B ports for pressure relief, allowing free cylinder floating during manual testing; Pressure Center (Type P) supplies compressed air to both working ports for synchronous clamping and force balance regulation. Running on filtered compressed air within 0.15~0.8 MPa under lubrication-free conditions, the valves work steadily at -20℃ to +70℃. Available specifications range from 4H200 to 4H400 with multiple thread options. Devoid of electrical components, the valves feature spark-free inherent explosion resistance, well-suited for flammable, dusty and high-risk production sites. They support panel mounting and base installation, frequently applied for production line manual commissioning, emergency pneumatic circuit cut-off, safety interlock loops and retrofitting replacement of automatic control valves.

SOLH KQ2W series 90° extended male thread push-in elbow, SMC KQ2W equivalent pneumatic fitting. Extended stem design solves mechanical interference for cylinders & vacuum circuits. PBT body + nickel-plated brass thread, supports PU/PA tube. Richge Technology with stable stock & reliable production for automation pneumatic tubing projects.

SOLH MHS3 3-jaw and MHS4 4-jaw wedge-cam self-centering hollow pneumatic grippers are fully interchangeable with equivalent SMC models. Wedge cam transmission drives synchronous jaw centering, achieving repeat positioning accuracy of ±0.01 mm. Bore sizes range from 16 to 125 mm. Standard double acting (D) design, with optional single acting normally closed (C) / normally open (E) spring return versions. The central hollow through hole allows routing of air tubes, ejector pins and optical fibers, supporting both external clamping and internal expanding gripping. Evenly spaced three jaws of MHS3 provide superior coaxiality, ideal for shafts, discs and ring-shaped workpieces. Orthogonally arranged four jaws of MHS4 deliver stable constraint for square, rectangular and irregular flat parts to avoid tilting. Built-in permanent magnets are compatible with M9BW series magnetic switches. The low-profile compact body fits robot end effectors perfectly. Derivative variants include dust-protected MHSJ3 and extended hollow MHSH3. Widely applied to machine tool loading/unloading, bearing press-fitting, handling of 3C circular & square components and concentric assembly of tubular workpieces.
