EGM43DTAS-S189

Edgeboard Connectors Overview

The EGM43DTAS-S189 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 86 positions arranged in two rows of 43 contacts each, with a pitch of 0.156 inches (3.96mm). The connector utilizes loop bellows contact types made from phosphor bronze, finished with 30.0µin (0.76µm) gold plating. Designed for through-hole, right-angle mounting, it accommodates a card thickness of 0.062 inches (1.57mm). The insulating material is polybutylene terephthalate (PBT), and the unit operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with loop bellows contacts for secure mating
• Right-angle through-hole mounting with top opening flange feature
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission
• Polybutylene terephthalate insulation supporting high-temperature operation

Edgeboard Connectors Applications

• High-density circuit board interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 'S189' matches the required flange and termination specifications for your design. Confirm that the 0.156-inch pitch aligns with the target card edge dimensions. Ensure the through-hole right-angle form factor fits the PCB layout constraints. Check RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. The loop bellows contact type offers robust retention compared to standard blade contacts. Consider the PBT insulation material for its thermal stability up to 125°C. The right-angle orientation facilitates compact vertical stacking or side-entry board arrangements.

Edgeboard Connectors Part Context

This part belongs to the EGM series of edgeboard connectors from Sullins Connector Solutions. The series provides various position counts and pitch options for different density requirements. The EGM43 variant specifically addresses applications needing 86 positions in a dual-row format. It shares common mounting and termination characteristics with other parts in the broader EGM family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EGM43DTAT-S189 and EGM43DTMS-S189, which share identical electrical and mechanical specifications. Verify that any replacement maintains the same 0.156-inch pitch and 86-position count. Ensure the contact material and plating thickness remain consistent for interface compatibility.
