GCM31DCMI

Edgeboard Connectors Overview

The GCM31DCMI is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 62 positions arranged in two rows of 31 contacts, with a 0.156-inch (3.96mm) pitch. Designed for through-hole mounting and solder termination, the connector utilizes phosphor bronze contacts with 30.0µin gold plating. The housing is made of black polyamide (PA9T), supporting PCB thicknesses up to 0.062 inches (1.57mm). It operates within a temperature range of -65°C to 125°C and includes flange features for side-mounted installation.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with 62 total contact positions
• Phosphor bronze contacts with 30.0µin gold plating for reliable signal transmission
• Polyamide (PA9T) insulation material ensuring thermal stability
• Side-mounted flange design for secure board attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard 0.156 inch pitch connectors
• Test and measurement devices needing high-cycle durability
• Automotive electronics operating in extreme temperature environments

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation against official Sullins Connector Solutions documentation to confirm exact flange orientation and mounting style. Ensure compatibility with target PCB thickness limits of 0.062 inches. Confirm RoHS compliance status if required by project specifications. Cross-reference lead times directly with authorized distributors as availability varies. Validate that the dual-edge female configuration matches the mating card requirements.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female interface with 62 positions is required. The 0.156 inch pitch suits applications needing wider spacing between contacts. Consider the side-mounted flange feature for mechanical stability during insertion. Verify that the operating temperature range meets environmental demands. Ensure the through-hole solder termination method aligns with assembly capabilities.

Edgeboard Connectors Part Context

This component belongs to the GCM31 series of card edge connectors from Sullins Connector Solutions. The series offers various mounting styles and contact configurations while maintaining consistent electrical characteristics. The GCM31DCMI specifically addresses needs for dual-sided connectivity with standardized dimensions. It complements other variants differing primarily in flange design and termination methods.

Edgeboard Connectors Replacement Considerations

Direct substitutes include GCM31DTKD-S288 and GCM31DCWS, which share identical electrical parameters and pin counts. Verify flange orientation differences before substitution. Ensure mating card specifications remain compatible with the replacement part's contact type.
