Qteatak 3 Pack Inlet Power Socket IEC320 C14
Premium 3-pin inlet sockets designed for IEC 320 C14 connections. Rated at AC 250V and 10A, they are formed from a combination of plastic and copper for durability, with compact mounting dimensions of 1″ x 0.7″. The design aligns with CE and UL standards, making it a flexible choice for equipment enclosures and power supplies. This pack is suited to projects requiring multiple inlets with straightforward mounting and reliable contact performance.
CNLINKO 3Pin Waterproof Industrial Connector
This LP16 3-Pin connector pair is engineered for rugged environments. With IP68 waterproof protection when mated, it provides excellent dust and water resistance for outdoor or wet settings. It accommodates 1.0-1.5 mm² cables (18-16 AWG) and supports over 500 cycles across -25°C to 85°C. It’s rated for 10A and 400V AC, with strong insulation and low contact resistance, making it a solid option for industrial equipment or field installations where moisture exposure is possible.
Lsgoodcare GX12-3pin Aviation Connector Kit
The GX12-3pin aviation connectors feature a metal shell with a zinc alloy exterior and silver-plated copper pins. They are designed for AC/DC applications up to 380V and 5A, with a straight plug configuration and cable attachments. The kit includes multiple pairs for versatile wiring in control panels, automation, or instrumentation setups. It’s suited for users needing rugged, compact 3-pin connections that stand up to vibration and mechanical stress.
Walfront GX16 3Pins Aviation Plug Socket
This GX16 3-pin aviation plug and socket set is designed for panel mounting and wire-ready connections. Rated for AC 250V and 5A, it’s a professional-grade solution for electrical panels and instrument housings. The metal shell and rigid construction help resist wear and tear in demanding environments, while the screw-type assembly ensures secure mounting and reliable conductivity across cycles.
DMLENGOIN IP68 3 Pin Waterproof Connector SP17
Offers IP68 waterproof protection with a SP17 3-pin configuration, designed for demanding environments. It uses gold-plated copper cores for improved conductivity and corrosion resistance, and is built to endure over 500 connection cycles under temperature swings from -40°C to 85°C. The connector emphasizes robust sealing and long service life for outdoor equipment, machinery, and marine applications.
Buying Guide
Key factors to consider when choosing a 3-pin plug and socket:
- Voltage and current ratings: Match the connector to your system’s voltage (commonly 125V-250V) and current (typically 5A-10A, higher for industrial equipment).
- Protection rating: IP68-rated connectors excel in wet or dusty environments; IP65 or IP54 may suffice indoors or sheltered areas.
- Connector family and style: GX12/ GX16 aviation connectors and IEC320 C14 inlets serve different form factors and mounting needs. Choose based on panel size, enclosure, and ease of wiring.
- Material and durability: Metal shells provide ruggedness and EMI shielding; plastic shells are lighter and cost-effective for less demanding uses.
- Cable compatibility: Check conductor size (AWG) and insulation thickness to ensure a secure fit and reliable contact.
- Mounting method: Screw-type, panel-mmount, or inline options affect ease of installation and serviceability.
- Environmental conditions: Consider temperature range, exposure to moisture, dust, and mechanical stress to select a suitable connector.
- Safety standards: Look for CE, UL, or other applicable certifications to ensure compliance with regional safety norms.
Additional Considerations and Comparisons
If you need a compact internal inlet for power supplies or equipment enclosures, IEC320 C14 inlets (like the QTEATAK option) provide a standardized mating connector with widely available cables. For outdoor or water-exposed applications, IP68-rated connectors such as the CNLINKO and DMLENGOIN lines offer better protection against moisture and dust. Aviation-style GX12 and GX16 connectors (Lsgoodcare and Walfront) deliver sturdy mechanical performance and are well-suited for control panels, robotics, and instrumentation where vibration resistance matters. When combining multiple 3-pin connections, verify that the mating pairs maintain the intended polarity and shield integrity to prevent miswiring or asymmetrical loading.
