Product Description

The NLJ-DN-1.27-D-20 is a compact, high-density 20-pin jumper header utilizing the NLJ-DN-1.27 connector series, designed for precision signal transmission in industrial automation and embedded systems. This 1.27mm pitch connector supports up to 20 discrete I/O connections, enabling direct interfacing with sensors, control modules, and communication boards. Operating within a voltage range of 5-24V DC and a temperature tolerance of -40°C to +85°C, it ensures reliability in harsh environments. The connector integrates seamlessly with common industrial communication protocols like I2C and SPI. Key advantages include space-saving design and robust gold-plated contacts for stable connectivity, though its small form factor requires careful handling during assembly. Suitable for robotics, instrumentation, and IoT devices, it features a durable 0.5A per-pin rating and 200-cycle mating durability.
