EEM36DRMT-S273

Edgeboard Connectors Overview

The EEM36DRMT-S273 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 72 total positions arranged in two rows of 36 contacts per row, with a contact pitch of 0.156 inches (3.96 mm). The connector utilizes loop bellows contact types made from phosphor bronze, finished with 10.0 µin (0.25 µm) gold plating. Designed for through-hole termination via wire wrap, it accommodates mating PCBs with thicknesses of 0.093 inches (2.36 mm) or 0.125 inches (3.18 mm). The insulator material is polyphenylene sulfide (PPS), and the unit operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with loop bellows contacts for secure board retention
• Wire wrap termination method for reliable electrical connection
• Polyphenylene sulfide insulation providing high thermal stability
• Gold-plated phosphor bronze contacts ensuring low resistance

Edgeboard Connectors Applications

• High-density circuit board interconnections requiring robust mechanical retention
• Industrial control systems operating in extreme temperature environments
• Telecommunications equipment utilizing standard card edge form factors
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify that the specific application requires wire wrap termination rather than solder, as this model lacks solder tails. Confirm the mating PCB thickness aligns with the supported 0.093-inch or 0.125-inch specifications to ensure proper insertion depth. Check for any required flange features, as this part number does not explicitly include threaded inserts or top-opening flanges in its designation compared to variants like RSM36DTBT-S273. Ensure compliance with RoHS standards if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with a 0.156-inch pitch is necessary for wire wrap processing. Compare against models with solder terminations if wave soldering is preferred. Consider the PPS insulator material for applications demanding higher heat resistance than standard nylon. Evaluate the 72-position count against available board space, noting the dual-row layout fits standard half-height card profiles.

Edgeboard Connectors Part Context

This connector belongs to the Sullins E-series family of card edge connectors, characterized by loop bellows contacts and various termination options. The EEM variant specifically denotes wire wrap termination. It shares dimensional similarities with other 0.156-inch pitch connectors but differs in termination style from solder-based counterparts like the EBM series. The design supports both .093-inch and .125-inch board thicknesses, offering flexibility in system integration.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include EBM36DRST-S273 if solder termination is acceptable instead of wire wrap. For identical wire wrap functionality, verify availability of equivalent 72-position, 0.156-inch pitch dual-edge connectors from the same manufacturer line.
