GCA49DTMT

Edgeboard Connectors Overview

The GCA49DTMT is a dual-row card edge connector manufactured by Sullins Connector Solutions. It features 98 total contacts arranged in two rows of 49 positions each, with a 0.125-inch (3.18mm) pitch. The connector utilizes female bellowed-type terminals with tin over nickel plating and phosphor bronze contact material. Designed for straight through-hole board mounting, it includes locking installation options and flush mount flange characteristics with top openings and 4-40 threaded inserts. The insulator is constructed from polyamide (PA9T), supporting a temperature range up to 150°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 98 female bellowed contacts for secure signal transmission
• Flush mount design featuring top opening flanges with 4-40 threaded insert capabilities
• Integrated locking mechanism ensures stable board retention during operation
• Polyamide (PA9T) insulation provides thermal stability and structural integrity

Edgeboard Connectors Applications

• High-density circuit board interconnections requiring robust mechanical retention
• Industrial control systems operating within extended temperature ranges
• Telecommunications equipment utilizing standard card edge form factors
• Automotive electronics modules demanding reliable solder termination

Edgeboard Connectors Procurement Notes

Verify the specific suffix DTMT confirms the tin over nickel plating and PA9T insulation material. Ensure the 4-40 threaded insert requirement aligns with panel mounting specifications. Confirm RoHS3 compliance status matches project regulatory requirements. Validate that the straight mounting orientation fits the PCB layout constraints without interference.

Edgeboard Connectors Selection Notes

Select this model when flush mounting with threaded fasteners is required rather than side-mounting. The bellowed contact type offers superior mating durability compared to standard leaf spring designs. Verify that the 0.125-inch pitch matches the target card edge thickness and guide rail specifications. Consider the 150°C maximum operating temperature for high-heat environments.

Edgeboard Connectors Part Context

This component belongs to the GCA49 series of card edge connectors from Sullins Connector Solutions. The series offers various termination and flange configurations to accommodate different mounting styles. The GCA49DTMT specifically addresses applications needing flush mounting with integrated locking features and durable tin-plated contacts.

Edgeboard Connectors Replacement Considerations

Cross-reference with GEA49DTMT for similar specifications but verify if the flange style or insulation material differs. Check GMA49DTMH for gold-plated alternatives if corrosion resistance is critical. Ensure any substitute maintains the 0.125-inch pitch and 98-contact count.
