ACC31DTAT-S189

Edgeboard Connectors Overview

The ACC31DTAT-S189 is a dual-edge card edge connector manufactured by Sullins Connector Solutions. It features 62 total positions arranged in two rows of 31 contacts, with a 0.100-inch (2.54mm) pitch. The connector utilizes beryllium copper ring bellows contacts with 30.0µin gold plating. Designed for through-hole right-angle mounting, it accommodates a 0.062-inch card thickness and operates within a temperature range of -65°C to 150°C. The insulating material is polyphenylene sulfide (PPS).

Edgeboard Connectors Feature Summary

• Dual-row configuration with 31 positions per side for high-density interconnection.
• Ring bellows contact type ensures reliable signal transmission via spring-loaded engagement.
• Right-angle through-hole termination facilitates PCB integration with standard soldering processes.
• Polyphenylene sulfide insulation provides thermal stability and mechanical durability.

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces.
• Telecommunications equipment utilizing standardized board dimensions.
• Computing hardware modules needing secure peripheral connections.
• Test and measurement instrumentation boards.

Edgeboard Connectors Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm flange characteristics and mounting hole configurations. Ensure compatibility with target card thickness and mating connector specifications. Cross-reference part numbers with authorized distributor catalogs to validate current availability and manufacturing status before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided, right-angle connection is required for 0.062-inch thick cards. Confirm that the 0.100-inch pitch aligns with existing PCB layout constraints. Verify that the operating temperature range meets environmental requirements. Check flange mounting options against chassis design specifications to ensure proper mechanical retention.

Edgeboard Connectors Part Context

This model belongs to the ACC series of card edge connectors from Sullins Connector Solutions. The series offers various position counts and contact types to suit different density needs. The ACC31 variant specifically addresses applications requiring moderate pin counts with reliable electrical performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other ACC series parts with identical pitch and row count but differing flange or contact materials. Verify mechanical fit and electrical ratings before swapping. Consult manufacturer cross-reference guides for approved alternatives with matching specifications.
