ABB25DHAN

Edgeboard Connectors Overview

The ABB25DHAN is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25 contacts with a 0.050-inch (1.27mm) spacing. The connector utilizes gold-plated beryllium copper clip-style wiper contacts and a black polyphenylene sulfide (PPS) insulator. Designed for through-hole mounting, it supports a card thickness of 0.062 inches (1.57mm). The unit operates within a temperature range of -65°C to 150°C and includes flange features for flush mounting with top openings and 4-40 threaded inserts.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with clip-style wiper contacts for reliable signal transmission
• Gold-plated beryllium copper terminals ensure corrosion resistance and conductivity
• Polyphenylene sulfide insulation provides high thermal stability and mechanical strength
• Flush mounting design with integrated flange and threaded insert options

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation against official Sullins documentation to confirm exact mounting style and contact configuration. Ensure compatibility with the target PCB layout regarding hole patterns and flange requirements. Confirm that the operating environment remains within the specified temperature limits and that the card thickness matches the 0.062-inch specification for proper engagement.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required with robust mechanical retention. The 0.050-inch pitch allows for significant I/O density in compact spaces. Consider the through-hole termination method for applications requiring strong solder joint integrity. Evaluate the need for the specific flange mounting features if panel or chassis integration is necessary for the assembly.

Edgeboard Connectors Part Context

This part belongs to the ABB series of high-density card edge connectors from Sullins Connector Solutions. The series is characterized by its use of clip-style wipers and PPS insulation materials. It is designed for demanding environments where reliability and thermal performance are critical. The ABB25DHAN specifically denotes the 50-position variant with dual-edge access and standard through-hole termination.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other Sullins ABB25 variants such as ABB25DHFT or ABB25DHLT, provided the mounting type and flange features align with the design requirements. Verify that any replacement maintains the same 0.050-inch pitch and 50-position count to ensure electrical and mechanical compatibility.
