Female Plug SP13 IP68 9-pin 3 A connector

Female Plug SP13 IP68 9-pin 3 A connector is a waterproof circular connector designed to provide secure electrical connections in demanding environments. The connector includes nine signal pins, each rated for up to 3 A, and an IP68-rated housing that protects contacts from dust and prolonged immersion in water. The shape and mating interface follow the SP13 form factor for compatibility with matching male SP13 connectors, facilitating reliable signal and low-power transmission for industrial, outdoor, and marine applications.

Advantages

The IP68-rated housing offers continuous protection against dust and temporary or prolonged water exposure, maintaining contact integrity in wet or dusty conditions. With nine pins and a 3 A per-pin current rating, the connector supports multiple signal or low-power circuits within a single compact footprint, reducing cabling complexity. Its circular design and keyed mating mechanism ensure correct orientation and straightforward connection, while robust construction increases resistance to mechanical stress and environmental degradation.

Suitable for

• Industrial control panels and sensor networks
• Outdoor lighting and signage installations
• Marine and offshore equipment requiring corrosion-resistant connections
• Automation systems and low-voltage power distribution
• Temporary or permanent field connections exposed to dust and moisture

Key specifications

• Connector type: female circular connector
• Pin count: 9
• Rated current: 3 A per pin
• Ingress protection: IP68 (dust-tight, protected against continuous immersion)
• Contact arrangement: multi-pin signal/low-power configuration
• Mechanical: keyed/coded mating interface for proper alignment
• Typical materials: corrosion-resistant metal contacts and sealed polymer housing
• Operating environment: suitable for wet, dusty, and outdoor conditions

How to use

Prepare conductor ends according to the connector manufacturer's recommendations and ensure correct wire gauge for a 3 A per-pin rating. Insert wires into the contact positions and secure them by crimping or soldering as specified by the contact type. Align the female plug with the corresponding SP13 male connector using its keyed features and mate until the coupling mechanism engages; verify firm connection and seal. When installing outdoors or in marine settings, route cables to minimize strain and avoid trapping moisture near the connector interface. Periodically inspect seals and contacts for corrosion or damage and replace any compromised components.

Usage recommendations

Use appropriate cable glands, strain reliefs, and gaskets to preserve IP68 performance. Select wire sizes and contact attachment methods (crimp or solder) that comply with the 3 A per-pin rating. For long-term outdoor or marine installations, apply corrosion inhibitors to exposed metal fasteners and schedule regular inspections to confirm continued sealing and electrical integrity.
