The 3P Connection Plug Fixed Part is an essential component in electrical switchgear systems, designed for reliable and secure electrical connections. Constructed from high-quality, durable materials, it ensures optimal performance even in demanding environments. This plug fixed part features three primary contacts, which are engineered to provide consistent electrical conductivity and stability, reducing the risk of connection failures or electrical faults.

An electrical switchgear gasket is a crucial component designed to provide a reliable seal between the various parts of a switchgear assembly, ensuring its safe and efficient operation. These Switchgear Door Padding is typically made from high-quality materials such as EPDM (Ethylene Propylene Diene Monomer), neoprene, silicone, or nitrile rubber, which offer excellent resistance to environmental factors like moisture, dust, and temperature fluctuations. The material choice depends on the specific application requirements, such as resistance to chemicals, UV rays, and ozone, as well as the operating temperature range of the switchgear.

SOLH MSQ rack-and-pinion rotary actuator is fully interchangeable with equivalent SMC rotary tables. Driven by symmetrical dual piston gear rack structure, it generates 3~4 times higher torque and superior radial & axial load capacity versus vane-type CRQ cylinders. Two grades are available: MSQB standard series with H9 tolerance and MSQA high-precision series featuring H8 fit and ±0.01mm repeat positioning accuracy. The rotary table is pre-machined with locating pin holes and fixture tapping holes, plus a central hollow through hole for wiring & tubing routing. Equipped with dual-end angle adjustment screws for infinitely adjustable swing range 0~190°, fixed 90°/180° swing variants are optional. Two damping solutions are offered: standard rubber bumpers and suffix-R integrated hydraulic shock absorbers (L low kinetic energy / H high kinetic energy). Dual piping layouts include default end-face ports and E side front ports. Built-in magnetic rings support M9BW reed switches to transmit position feedback signals to PLC. Frame sizes range from 10 to 200, pre-filled with long-life grease for lubrication-free operation. Widely applied to PCB optical inspection, microchip precision positioning, packaging direction switching, machine tool workpiece flipping and mini manipulator end rotary joints for indexing, turnover and multi-angle positioning automation.

SOLH 50 series flameproof pilot solenoid valves cover two models: 50-VFE 5/2 spool valve and 50-VPE 3/2 poppet valve. Certified Ex d Ⅱ BT4, CCC, TIIS & IEC with IPX6 protection, they apply to Zone 1 & Zone 2 flammable and explosive environments such as lithium coating, chemical, painting and oil & gas workshops. Both share interchangeable 3.5W low-power flameproof coils and housings, while their manifold bases are non-interchangeable. 50-VFE requires 0.15MPa differential pressure and only works for positive-pressure double-acting cylinder circuits, incompatible with vacuum. 50-VPE features zero-pressure startup, stable under full vacuum down to -101.2kPa and automatic pressure relief upon power loss for vacuum handling and single-acting cylinders. Lubrication-free design allows single threaded mounting or multi-station manifold valve island assembly with certified flameproof wiring fittings, providing safe standard pneumatic switching for explosion-proof industrial production lines.

Auxiliary Contact Switch The Auxiliary Contact Switch is a switch used in electrical equipment to extend the signal transmission function, assisting in the condition detection of main circuit equipment and providing additional switching signals during signal transmission. It acts as an auxiliary device to the main switch, providing additional contact signals to meet complex electrical control and indication requirements. Used to feedback, control, protect or indicate the status of a system, especially in automation and monitoring systems, plays a vital role. The auxiliary switch consists of a set of normally open (NO) and normally closed (NC) contacts that are synchronized with the state of the main switchgear. When the main device is operating, the contact of the auxiliary switch will be opened or closed according to the operating state of the device, thereby transmitting the signal to the control system or indicating device.
