Description

Key Advantages

Rugged Metal Construction: Engineered with a premium zinc alloy chrome-plated shell, the SD20 series provides superior impact resistance and durability, outperforming plastic alternatives in harsh industrial or high-traffic operational environments.
High-Temperature Insulation: Utilizing PPS thermoplastic insulation, these connectors can withstand extreme temperatures up to 260℃, ensuring electrical stability and preventing housing deformation during high-intensity soldering or long-term operation.
Superior Conductivity: Equipped with gold-plated brass contacts, the SD20 maintains low contact resistance and prevents oxidation, guaranteeing reliable signal integrity and efficient power flow over 500+ mating cycles.
Versatile Mounting & Wiring: We offer flexible installation options including square flange panel mounting and angled back shells, supporting soldering, crimping, and screw termination to fit diverse engineering requirements.
Certified Environmental Safety: Our SD20 series is fully compliant with CE, RoHS, and UL standards, providing an IP65 waterproof rating that protects critical electrical connections against dust, moisture, and low-pressure water jets.

FAQ

Q1: What is the benefit of the threaded coupling mechanism?
The threaded mechanism provides a highly secure, vibration-resistant, and robust connection compared to snap-lock types, ideal for high-power applications where safety and stability are paramount.
Q2: What are the specific current ratings for this series?
According to Elecbee, the 2-pin and 3-pin configurations are rated for 10A, while the 4-pin through 10-pin configurations are rated for 5A.
Q3: Is the IP65 rating sufficient for outdoor use?
IP65 protects against dust and water splashes/jets. It is suitable for most industrial outdoor applications where continuous submersion is not a factor.
Q4: What temperature can the internal insulator handle?
The PPS thermoplastic insulator can handle temperatures up to 260℃, according to eBay product specifications.
