Norcomp Right Angle 25 Contacts 2.769 mm Pitch PCB D-Sub Connector with 4 to 40 Insert 189-025-313R491

Norcomp 189-025-313R491 is a right angle PCB mount D-Sub connector with a precise 2.769 mm pitch and 25 contacts per port, designed for efficient space utilization on printed circuit boards. It features dual stacked ports to maximize connector density, addressing the needs of compact industrial and electronic applications.

This connector’s outer shell is constructed from nickel plated steel with ground indents enhancing shielding effectiveness and providing improved electrical grounding and mechanical retention. The stamped brass contacts are gold plated for enhanced conductivity and resistance to wear and corrosion, assuring long-lasting performance even under demanding conditions.

The connector supports a current rating of 5 amperes and a dielectric voltage rating of 1 kV, suitable for various industrial electronic devices and communication systems. Termination is via solder type, ensuring reliable electrical connections on PCB mountings. Operating temperature ranges from -55°C up to 105°C thanks to the high-temperature UL94V-0 thermoplastic insulator rated for 260°C process temperature.

Mounting is facilitated via boardlocks for secure placement on PCB, with a choice between 4-40 flush inserts or 4-40 hex standoffs providing versatile mechanical support. This model is part of the Norcomp 189 series of stacked D-sub connectors known for their compact footprint and robust industrial performance.

This right angle connector is ideal for use in electronic assemblies with limited PCB space requiring dual port connections. The nickel plated steel shell offers improved EMI shielding and mechanical strength. Gold plated contacts provide consistent electrical performance and corrosion resistance.

High temperature resistant thermoplastic insulator ensures operation in demanding thermal environments. Boardlocks and mounting hardware options secure the connector rigidly on the PCB.

Applications include industrial electronics, telecommunications equipment, instrumentation, and embedded system interfaces. This connector supports reliable high current and voltage connections with compact form factor suitable for modern circuit board layouts.
