AMM31DTBN-S189

Edgeboard Connectors Overview

The AMM31DTBN-S189 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. The connector utilizes phosphor bronze contacts with a gold plating thickness of 30.0µin (0.76µm). Designed for through-hole right-angle mounting, it accommodates a card thickness of 0.062 inches (1.57mm). The housing is made of polybutylene terephthalate (PBT) and is colored green. Operating temperature ranges from -65°C to 125°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix 'S189' against the manufacturer's current documentation to ensure compatibility with required flange features and environmental certifications. Confirm that the 0.156-inch pitch aligns with the target card edge specifications. Cross-reference the gold plating thickness requirements with application standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with a 0.156-inch spacing is required. Ensure the design supports right-angle mounting and through-hole soldering. Verify that the operating temperature range up to 125°C meets the system's thermal profile. Confirm that the 0.062-inch card thickness specification matches the mating board dimensions.

Edgeboard Connectors Part Context

This part belongs to the AMM series of card edge connectors from Sullins Connector Solutions. The series offers various pin counts and spacing options. The AMM31 variant specifically provides 31 pins per row, totaling 62 positions. It is designed for robust industrial applications requiring durable electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other Sullins models with identical 0.156-inch pitch and 62-position dual-edge configurations. Verify mechanical fit and electrical ratings before swapping. Generic equivalents may lack the specific gold plating thickness or PBT material properties.
