China Switchgear Interlocking Assembly Manufacturer, Supplier, Factory

SOLH VR3200/VR3201 power-free mechanical pneumatic-electric relay is fully interchangeable with matching SMC models. It converts air pressure signals into 1NO+1NC dry contact signals without external power supply for PLC interlock, pressure monitoring and fault alarm, with adjustable trigger pressure ranging from 0.1 to 1.0MPa and high-load built-in micro switch. Three variants are available: open-frame VR3200 for dry dust-free control cabinets; fully sealed IP44 drip-proof VR3201 for humid & dusty machine tools and production lines; CE-certified VR3202 with dedicated grounding terminal for strong EMC interference and export machinery. Equipped with standard Rc1/8 air inlet, brass valve body, POM piston, stainless steel return spring and NBR seal, it is widely used for cylinder clamping pressure confirmation, vacuum chuck negative pressure feedback, main air source low-pressure warning and signal conversion in explosion-prone workshops without electronic sensors.

The Vertical Busbar Support is a critical component in electrical switchgear systems, specifically designed to provide robust and reliable support for vertical busbars. Constructed from high-strength, insulating materials such as fiberglass-reinforced polyester or epoxy, these supports ensure optimal electrical insulation and mechanical stability. They are engineered to withstand high mechanical stress and thermal expansion, maintaining the busbars' alignment and preventing sagging or misalignment that could lead to electrical faults.

SOLH MXH narrow compact pneumatic slide table is interchangeable with SMC MXH series. Driven by dual piston and equipped with circulating ball guide rail, it adopts ultra-narrow body suitable for dense side-by-side layout. It features excellent anti-offset and anti-torsion capacity with allowable torque around 6 times of traditional MXU slides, repeat positioning accuracy ±0.02mm and maximum standard stroke up to 60mm. Supporting 4-direction mounting and 3-side piping, it comes with built-in magnet compatible with various magnetic switches, dual-end rubber buffers and enables continuous oil-free operation. Bore sizes φ6~20mm, widely used for medium-precision long-stroke high-frequency transfer of 3C components and small plastic parts under cantilever or unilateral load in space-limited automation equipment.

Switchgear insulating material is essential in electrical systems to provide safety, efficiency, and reliability. These materials are typically used in the construction of switchgear assemblies to prevent electrical currents from unintentionally passing through different components, reducing the risk of short circuits, electrical fires, and equipment damage. The most common insulating materials used in switchgear include epoxy resin, glass-reinforced polyester (GRP), and various types of thermoplastics, each selected for their unique properties, such as high dielectric strength, excellent thermal stability, and resistance to moisture and chemical corrosion.

Richge is a manufacturer of Switchgear Secondary Socket Interlocks in China, specializing in high-precision components designed to enhance the safety and functionality of electrical switchgear systems. Our secondary socket interlocks are engineered to prevent unauthorized or incorrect operations, ensuring reliable and secure management of switchgear equipment.

SOLH DSNU stainless steel mini pneumatic cylinders strictly comply with ISO 6432 & CETOP RP52P international standards, fully interchangeable with FESTO DSNU original cylinders, also compatible with SMC CM2 and Airtac MG series for direct drop-in replacement. Constructed entirely from SUS304 stainless steel barrel and piston rod with forged aluminum end caps, it delivers outstanding rust-proof and anti-corrosion capability to withstand high humidity, weak acid and weak alkali environments, perfectly suited for food, pharmaceutical and hygienic-grade production lines. Roller crimped end cap connection ensures robust structural stability against vibration. It supports diverse variants including double-acting, spring single-acting and DSNU-S ultra-short compact version; optional PPV self-adaptive air cushion automatically adjusts damping across 0.1~1.0MPa pressure range for stable high-speed reciprocation. Low-friction composite sealing enables oil-free operation with service life over 8 million cycles; built-in magnetic ring option works with mainstream magnetic sensors for PLC position feedback. We maintain stable mass production and sufficient global spot inventory, widely deployed in food processing, medical packaging, electronics assembly and harsh-condition automated stations.
