GBM25DCBH-S189

Edgeboard Connectors Overview

The GBM25DCBH-S189 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25, with a pitch of 0.156 inches (3.96mm). Designed for through-hole right-angle mounting, the contacts are made of phosphor bronze with a gold finish thickness of 10µin (0.25µm). The connector utilizes hairpin bellows contact types and supports a card thickness of 0.062 inches (1.57mm). Insulation material is unspecified in available data, and it operates within a temperature range of -65°C to +125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified board applications
• Hairpin bellows contact type ensures reliable signal transmission
• Right-angle through-hole mounting facilitates PCB integration
• Gold-plated phosphor bronze contacts provide corrosion resistance

Edgeboard Connectors Applications

• High-density interconnection systems requiring dual-edge access
• Industrial control boards utilizing standard 0.062 inch card thickness
• Electronic assemblies operating within -65°C to +125°C environments

Edgeboard Connectors Procurement Notes

Verify that the specific suffix S189 aligns with your required insulation color or flange characteristics, as datasheets may vary. Confirm the exact gold plating thickness specification against the latest manufacturer documentation to ensure compliance with your signal integrity requirements. Ensure the receiving PCB footprint matches the 0.156 inch pitch and right-angle orientation before ordering.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156 inch pitch is required for right-angle mounting. It is suitable for applications needing 50 positions with hairpin bellows contacts. Consider the -65°C to +125°C operating range and 0.062 inch card thickness compatibility. Verify if the specific flange or locking features match the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the Sullins Connector Solutions edgeboard connector family, specifically designed for dual-edge card applications. It shares common interface standards with other models in the series but differs in position count and pitch. The GBM25DCBH-S189 is distinct from the 0.100 inch pitch variants like the ECC55DCCI-S189, offering a wider spacing for different board density requirements.

Edgeboard Connectors Replacement Considerations

Direct substitutes include GBM25DCAH-S189 and GBM25DCCI-S189, which share similar 50-position dual-edge specifications. Verify that the replacement maintains the 0.156 inch pitch and right-angle mounting style. Ensure the contact material and plating thickness meet the original performance criteria.
