Socket SP21 female 5‑pin IP68 waterproof connector

SP21 female socket with 5 pins and IP68 protection rating is a waterproof electrical connector designed for outdoor and harsh-environment installations. The connector provides five secure contacts in a compact circular housing and a sealed interface that resists dust ingress and temporary immersion. It is intended for reliable signal and power transmission where a durable, weatherproof connection is required.

Advantages

The SP21 female socket offers an IP68-rated sealing level that protects contacts from dust and temporary submersion, combined with five firmly held female contacts for consistent electrical continuity. Its circular form factor and threaded coupling ensure straightforward mating and mechanical stability in vibration-prone environments. Constructed from materials suitable for outdoor use, the connector simplifies installation while reducing the need for additional protective enclosures.

Suitable for

• Outdoor lighting connections (street lights, architectural fixtures)
• Industrial automation sensors and actuators
• Cable runs exposed to dust, moisture, or temporary immersion
• Marine and coastal equipment with splash and spray exposure
• Temporary or permanent field installations requiring robust connectors

Key specifications

• Contact configuration: 5 female contacts
• Protection class: IP68 (dust tight and protected against continuous immersion)
• Connector type: circular, threaded coupling
• Contact material and plating: corrosion-resistant conductive contacts (manufacturer dependent)
• Operational environment: suitable for outdoor and industrial ambient conditions
• Typical applications: power and signal connections for lighting, automation, and industrial equipment

How to use

Prepare cable ends according to the connector's contact size and insulation requirements, ensuring proper stripping and routing to avoid stray strands. Insert conductors into the corresponding female contacts and secure them as specified by the connector's assembly method (crimping or soldering if applicable). Align the mating male and female shells, then engage the threaded coupling to form a sealed connection; tighten to the recommended torque to achieve IP68 sealing. Inspect the assembled connector for correct contact seating and intact seals before placing the connection into service.

Usage recommendations

For sustained IP68 performance, verify that cable diameters match gland specifications and that sealing elements are free of debris or damage. Avoid excessive bending or mechanical strain at the cable entry, and follow the manufacturer's assembly instructions for contact termination and torque values. Periodically inspect outdoor connections for wear, corrosion, or seal deterioration, especially after prolonged exposure to harsh environments.
