GCM25DTMN-S189

Edgeboard Connectors Overview

The GCM25DTMN-S189 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25, with a pitch of 0.156 inches (3.96 mm). Designed for through-hole right-angle mounting, the contacts are made of phosphor bronze with a gold finish thickness of 30 µin (0.76 µm). The insulator is constructed from polyamide (PA9T) nylon and supports a card thickness of 0.062 inches (1.57 mm). The operating temperature range is -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with loop bellows contact type for secure board insertion
• Right-angle through-hole termination compatible with standard soldering processes
• Polyamide insulation material providing thermal stability within specified operating ranges

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required pitch and termination style. Confirm the gold plating thickness meets application requirements. Ensure the PCB layout accommodates the right-angle footprint and row spacing. Check compatibility with the target card thickness specification before ordering.

Edgeboard Connectors Selection Notes

Select this component when a 0.156-inch pitch dual-edge interface is required. Consider the right-angle orientation for space-constrained vertical mounting. Evaluate the phosphor bronze contact material for mechanical durability. Verify that the PA9T insulator rating aligns with the environmental temperature conditions of the end-use application.

Edgeboard Connectors Part Context

This part belongs to the GCM series of card edge connectors designed for high-reliability applications. The series offers various pitch options and termination styles. The GCM variant specifically utilizes polyamide insulation and phosphor bronze contacts, distinguishing it from other materials in the broader product line.
