GMM24DTMS

Edgeboard Connectors Overview

The GMM24DTMS is a dual-edge card connector manufactured by Sullins Connector Solutions. It features 48 positions arranged in two rows of 24 contacts each, with a 0.156-inch (3.96mm) pitch. The connector utilizes female bellowed contacts made from phosphor bronze with a 30.0µin gold plating thickness. Designed for through-hole right-angle mounting, it accommodates a card thickness of 0.062 inches. The insulator is constructed from polyamide (PA9T), and the unit operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 48 total contact positions for high-density interconnect applications.
• Bellowed contact design ensures reliable mating force and signal integrity across repeated insertions.
• Right-angle through-hole termination facilitates standard PCB layout integration.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Computing hardware edge-card connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix 'DTMS' against official Sullins documentation to confirm flange characteristics and mounting orientation. Ensure compatibility with 0.156-inch pitch requirements and 0.062-inch card thickness specifications before procurement. Cross-reference RoHS compliance status with current manufacturer declarations.

Edgeboard Connectors Selection Notes

Select this model when a dual-sided edge connector with a 0.156-inch pitch is required. Confirm that the right-angle through-hole mounting style aligns with the PCB assembly design. Verify that the phosphor bronze material and gold plating meet the environmental and durability standards for the intended application.

Edgeboard Connectors Part Context

This component belongs to the GMM series of card edge connectors from Sullins Connector Solutions. The series offers various pitch options and mounting styles. The GMM24 variant specifically denotes a 24-position per row configuration, totaling 48 contacts, designed for robust industrial and commercial electronic interconnections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include GMM24DRMT for round-wire termination or GMM24DSXS for straight mounting. Verify that alternative part numbers maintain the identical 0.156-inch pitch and 48-contact count to ensure mechanical and electrical compatibility.
