ABM31DTMS-S189

Edgeboard Connectors Overview

The ABM31DTMS-S189 is a board-to-board connector assembly manufactured by Sullins Connector Solutions. It features a dual-row, male pin configuration with a total of 60 contacts arranged in a 2x30 layout. The connector utilizes a surface mount termination style designed for automated placement on printed circuit boards. Key electrical specifications include a rated current of 2.0 A per contact and a voltage rating of 50 V AC. The insulation resistance is specified at a minimum of 1000 MΩ, while the dielectric withstand voltage is 1000 V AC for one minute. The operating temperature range extends from -55°C to +125°C.

Edgeboard Connectors Feature Summary

• Dual-row male pin design facilitates high-density interconnections between stacked circuit boards.
• Surface mount termination ensures secure attachment and alignment during automated PCB assembly processes.
• Robust insulation properties provide reliable electrical isolation under standard operating conditions.

Edgeboard Connectors Applications

• High-density server backplane interconnects
• Industrial control system module stacking
• Telecommunications equipment internal board connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required lead frame length and plating specification. Confirm compatibility with mating receptacle part numbers to ensure proper pin engagement. Check RoHS compliance status if restricted substances are mandated by project requirements. Ensure storage conditions prevent contamination of gold-plated contacts prior to assembly.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-row male connector is required for vertical board-to-board applications. Consider the 2.54 mm pitch requirement against available board trace widths. Evaluate the mechanical retention needs of the surface mount footprint against vibration environments. Ensure the mating connector supports the specified current load without excessive heating.

Edgeboard Connectors Part Context

This part belongs to the ABM series of board-to-board connectors, which are engineered for compact electronic assemblies. The series offers various row counts and termination styles to accommodate different stack heights and mounting orientations. It serves as a critical interface component in systems requiring reliable signal and power transmission between adjacent or stacked PCBs.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 2x30 pin count, 2.54 mm pitch, and surface mount male termination. Verify identical housing height and guide pin configurations if mechanical alignment is critical. Cross-reference mating part numbers to ensure functional interchangeability without redesigning the host board.

Edgeboard Connectors FAQ

What is the contact material for this connector?

The contacts are typically made from phosphor bronze with a gold flash plating to ensure conductivity and corrosion resistance.

Does this connector include guide pins?

Guide pins are often included in the assembly to assist with precise alignment during insertion into the mating receptacle.
