WEIPU SP Series Socket — Rugged Circular Industrial Connectors

The WEIPU SP series socket combines compact circular design with robust protection to deliver dependable connectivity where failure is not an option. Designed for harsh industrial environments, these sockets give engineers and procurement teams predictable performance, easier installation, and long service life—backed by WEIPU’s nearly 30 years of connector expertise and industry-leading manufacturing capacity.

Why the WEIPU SP series socket matters

Connectivity is the quiet backbone of modern systems. The SP series socket answers the need for compact, sealed circular connections that perform consistently under vibration, moisture, dust, and temperature swings. For system integrators and maintenance teams, the SP family reduces downtime by simplifying mating operations and providing repeatable electrical and mechanical performance. The design philosophy centers on practical reliability: right-sized contacts, positive locking, and sealing strategies that protect the interface without adding unnecessary bulk.

Core features, variants, and practical benefits

Rather than a one-size-fits-all approach, WEIPU offers SP series sockets in multiple configurations so you can match form factor and performance to the application. These connectors excel in environments where space, protection, and quick servicing matter—examples include factory automation, outdoor sensors, battery management systems, and compact medical equipment.

• Form factors: panel-mount and cable-mounted sockets engineered for compact circular mating and easy panel integration.
• Environmental sealing: designs are available to meet demanding ingress protection classes, benefiting installations exposed to dust, water jets, and washdown procedures.
• Secure locking options: tactile or threaded locking ensures vibration resistance and predictable unmating force for safe maintenance cycles.
• Contact choices: multiple pin counts and contact styles support signal, mixed power/signal, and shielded arrangements to suit diverse electrical needs.
• Serviceability: field-replaceable cable assemblies and straightforward panel mounting speed repairs and lower mean time to repair (MTTR).
• Scalability: while SP series focuses on compact circular connections, it is supported by WEIPU’s broader ecosystem of circular, heavy-duty, and CEE products for larger power or specialized needs.
