LD20/SP20 Industrial Flange Connector Dimensions and Specs
LD20/SP20 2-7 Pin Waterproof Rear Nut Connector
Reliable Waterproof Connection for Outdoor and Industrial Use
The LD20/SP20 waterproof rear nut mount connector is designed for stable power and signal connections in harsh environments. With an IP68 waterproof structure, it helps protect cable connections from water, dust, moisture, and outdoor exposure. The threaded locking design keeps the connector firmly connected, making it suitable for equipment that requires long-term reliable operation.

Flexible 2-7 Pin Options for Different Projects
This series is available from 2 pin to 7 pin, allowing customers to choose the right version according to wiring needs. 2 pin, 3 pin, and 4 pin models are suitable for higher current power connections. 5 pin, 6 pin, and 7 pin models are ideal for applications that need multiple signal or control lines.
Different mounting types are available, including in-line type, rear-nut mount, 2-hole flange mount, and 4-hole square flange mount. For detailed dimensions and specifications, refer to the LD20/SP20 Industrial Flange Connector Dimensions and Specs.

Built for Durability and Long Service Life
The connector shell is made of strong engineering plastic (PC, Nylon66) with good flame resistance and impact resistance. The internal insulation part is made of high-temperature-resistant PPS material, helping the connector remain stable during long-term use. Brass contacts with gold-plated surface provide reliable conductivity and help reduce connection loss.
The screw termination structure makes wiring simple and secure, which is convenient for installation, maintenance, and replacement.
Suitable for a Wide Range of Applications
This waterproof cable connector can be used in outdoor LED lighting, industrial automation, marine equipment, communication devices, security systems, medical equipment, power equipment, and other electrical connection projects. It is especially suitable for applications where the cable connection needs to resist water, dust, vibration, and repeated plugging.
Selection Considerations
- Confirm the required pin count (2-7) based on your power and signal line needs.
- Verify the mounting style: rear-nut, in-line, 2-hole flange, or 4-hole square flange.
- Check the cable outside diameter and conductor size to ensure a proper fit with the screw termination.
- Specify the mating-side requirement (male or female) and pinout or drawing for accurate matching.
