What is the LP20 Solder Type Wire-to-Wire Waterproof Connector?
This industrial circular connector features a 20mm shell specifically designed for wire-to-wire applications. Unlike panel-mount versions, it enables seamless in-line cable extensions and mobile equipment connections.
The design addresses critical challenges you face daily:
- Signal instability in high-vibration environments
- Contact degradation from moisture ingress
- Need for permanent, low-resistance terminations
Its precision solder cups deliver superior electrical continuity. The multi-pin architecture accommodates diverse circuit requirements. The secure snap-lock mechanism maintains connection integrity where standard connectors fail under water, dust, or mechanical stress.
You get a proven solution that eliminates downtime caused by environmental factors.

Electrical Ratings
The LP20 Solder Type Wire-to-Wire Waterproof Connector delivers impressive performance:
- Current capacity: 5A to 20A depending on pin count
- Operating voltage: Up to 500V
- Wire gauge support: 0.34-4.0mm² (24-12 AWG)
- Insulation resistance: >500MΩ
Environmental Protection
You receive comprehensive protection:
- IP67/IP68 rating when properly mated
- Complete submersion resistance
- Operating temperature: -40°C to +105°C
- Salt spray tested for 72 hours
- Meets CE, RoHS, and UL standards
The solder-type termination outperforms crimp methods by delivering lower resistance and superior mechanical strength. This translates to fewer field failures and reduced maintenance costs for your operations.
Key Technical Advantages
1. Quick-Connect Bayonet System
The snap-lock coupling enables one-handed operation. You'll hear an audible click confirming secure engagement. This feature proves invaluable during installation in confined spaces or when working alone.
2. Superior Sealing Technology
IP68-rated silicone sealing rings provide dust-tight protection. Your connections remain reliable even during temporary submersion. The multi-stage seal design guards against water intrusion at cable entry points.
3. Versatile Housing Options
Choose between:
- Zinc alloy: Maximum impact resistance for industrial machinery
- PBT plastic: Lightweight solution for mobile applications
Both options deliver UL94 V-0 flame retardancy and exceptional UV stability.
4. Extended Service Life
Gold-plated contacts tested for thousands of mating cycles ensure long-term reliability. You minimize replacement frequency in high-use applications. The robust construction withstands the rigors of outdoor deployment.
5. Flexible Configuration
Accommodates 2 to 12 pins with current ratings reaching 30A. This versatility supports both power distribution and signal transmission. You can standardize on one connector family across multiple applications.
6. Harsh Environment Performance
Salt spray compliance and UV resistance make this connector ideal for coastal installations. The housing maintains structural integrity through temperature cycling and chemical exposure.
Real-World Applications
Outdoor LED & Stage Lighting
You'll find these connectors cascading large-scale outdoor displays and architectural lighting systems. They withstand rain, humidity, and temperature fluctuations during repeated setup and teardown cycles. The quick-connect design accelerates installation while maintaining waterproof integrity.
Renewable Energy & Smart Agriculture
Solar PV monitoring sensors and automated irrigation controllers rely on this connector in field environments. Constant soil moisture and UV exposure demand the robust protection only IP68-rated solutions provide. Your distributed systems maintain communication reliability season after season.
Marine & Industrial Automation
Underwater sensors, offshore communication equipment, and robotic arms in wash-down zones depend on these connectors. High-pressure water jets and salt spray pose no threat to properly installed units. The solder termination ensures connection stability even under continuous vibration.
The LP20 Solder Type Wire-to-Wire Waterproof Connector serves as the primary interface where reliability cannot be compromised.

Frequently Asked Questions
Q: What is the most extreme wire gage backed by the LP20 patch cups?
A: For 2 and 3-pin arrangements, you can utilize up to 12-14 AWG (roughly 2.5-4.0mm²). Higher stick checks (9-12 stick) oblige 18-24 AWG wire.
Q: Can these connectors be utilized in saltwater environments?
A: Yes. Select the zinc amalgam or PBT shell adaptation for saltwater applications. The IP68 rating and gold-plated contacts particularly stand up to salt-induced corrosion.
Q: What is the suggested patching temperature?
A: We prescribe 380°C ±10°C for no more than 3 seconds per stick. This guarantees strong joints without harming the inner PBT insulator.
Q: Does the wire-to-wire adaptation incorporate the backshell and cable gland?
A: Yes. The LP20 wire-to-wire set incorporates a waterproof cable organ (tail nut) that compresses the inner elastic seal around your cable jacket.
Q: Is it consistent with other LP arrangement shell sizes?
A: No. The LP20 particularly alludes to the 20mm breadth. It is not cross-compatible with LP12, LP16, or LP24 arrangement. This guarantees a keyed and standardized fit inside the 20mm ecosystem.
Q: How do I confirm legitimate installation?
A: After fastening, perform a tender drag test on each wire. Tune in for the capable of being heard press when mating connectors. Conduct a visual assessment of the cable organ compression.
Q: What customization choices are available?
A: Cablein offers custom stick checks, lodging materials, cable lengths, and wire gages. Contact our building group to examine your particular requirements.
