Product Overview

The DJL series connectors are specialized interface products designed for modular power supplies. They are fully interchangeable with comparable products from other manufacturers and have obtained UL safety certification (E319259). This series utilizes single-leaf hyperboloid spring sockets and crown spring sockets as contact elements, thereby ensuring high dynamic contact reliability.

The DJL 14-14 Industrial Modular Connector is engineered for high-performance power applications. With a rated current of 75A and a mechanical life of 500 cycles, it combines robust reliability with low contact resistance, making it ideal for PCB connections, modular power supply systems, and UPS applications.

Why choose this connector:

High-current capacity ensures stable power supply even under load fluctuations

Smooth mating and unmating for effortless assembly and maintenance

Durable in extreme conditions: temperature range of -55°C to +125°C and resistance to vibration and impact

Dynamic contact reliability thanks to silver-plated beryllium copper contacts

This connector is not just a plug—it is a critical component in industrial modular connector solutions where reliability and safety cannot be compromised.
