GEM08DTMH-S189

Edgeboard Connectors Overview

The GEM08DTMH-S189 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 16 positions arranged in two rows of eight, with a pitch of 0.156 inches (3.96 mm). Designed for through-hole right-angle mounting, the connector utilizes phosphor bronze contacts with a tin finish thickness of 100 µin (2.54 µm). The housing is constructed from black polyamide (PA9T) nylon and supports a card thickness of 0.062 inches (1.57 mm). Operating temperatures range from -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with loop bellows contact type
• Right-angle through-hole termination for PCB integration
• Tin-plated phosphor bronze contacts for reliable signal transmission
• Polyamide insulation material rated for extended temperature ranges

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics board-to-board connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix S189 corresponds to the required packaging and lead time specifications provided by the manufacturer. Confirm compatibility with standard reflow soldering profiles for tin finishes. Ensure procurement channels are authorized to guarantee component authenticity and traceability. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this connector when a 0.156-inch pitch dual-edge interface is required for non-specified cards. The right-angle form factor suits space-constrained vertical mounting scenarios. Consider the tin finish for cost-effective applications where gold plating is unnecessary. Validate that the 0.062-inch card thickness matches the target PCB design constraints.

Edgeboard Connectors Part Context

This component belongs to the GEM series of card edge connectors from Sullins Connector Solutions. The series offers various pin counts and pitches to accommodate different edge card requirements. The GEM08 variant specifically addresses mid-density applications requiring 16 positions. It complements other Sullins products designed for robust mechanical retention and electrical stability in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same family include GEM08DCAN-S189, which shares identical dimensions but differs in contact finish and material composition. Verify that alternative parts maintain the same pitch, row count, and mounting style to ensure mechanical fit without redesigning the PCB footprint.
