ESA31DTMN

Edgeboard Connectors Overview

The ESA31DTMN is a dual female card edge connector manufactured by Sullins Connector Solutions. It features 62 positions arranged in two rows with 31 contacts per row. The connector utilizes a 0.125-inch (3.18mm) pitch and is designed for through-hole, right-angle mounting. Contact material is phosphor bronze with a gold plating thickness of 30.0µin (0.76µm). The insulator is made of polybutylene terephthalate (PBT), supporting a card thickness of 0.062 inches (1.57mm). Operating temperature ranges from -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for high-density signal transmission
• Right-angle through-hole termination for secure PCB integration
• Gold-plated phosphor bronze contacts ensuring reliable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact contact plating specifications and insulation material properties. Ensure that the selected variant matches the required card thickness and operating temperature range for the target application environment. Cross-reference the part number with current RoHS compliance certificates to meet regulatory standards.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female interface with a 0.125-inch pitch is required for right-angle board-to-board connections. Consider the PBT insulation material and specified temperature range for environmental compatibility. Evaluate the mechanical stability provided by the through-hole mounting style against space constraints on the printed circuit board layout.

Edgeboard Connectors Part Context

This model belongs to the ESA series of edgeboard connectors from Sullins Connector Solutions. The series provides various position counts and pitch options for different connectivity needs. The ESA31DTMN specifically addresses applications needing 62-position dual-row interfaces with standard industrial durability characteristics.

Edgeboard Connectors Replacement Considerations

Consult official substitution guides for compatible alternatives within the same series or equivalent products from other manufacturers. Verify pin count, pitch, and mounting orientation before swapping components.
