MPSL-1100-70-DR-5HKY

Edgeboard Connectors Overview

The MPSL-1100-70-DR-5HKY is a dual female edge card connector manufactured by Sullins Connector Solutions. It features 140 total positions arranged in two rows of 70 pins each, with a 0.100 inch (2.54mm) spacing. The connector utilizes gold-plated phosphor bronze contacts with a 30.0µin thickness and full bellows contact types. Designed for through-hole mounting, it supports PCBs up to 0.062 inches thick. The insulating material is polybutylene terephthalate (PBT), rated for operation between -65°C and 125°C.

Edgeboard Connectors Feature Summary

• Dual-sided female configuration providing 140 connection points across two parallel rows
• Full bellows contact design ensures reliable mating force and signal integrity
• Gold-plated phosphor bronze terminals offer corrosion resistance and low contact resistance
• Side-mounting flange with unthreaded openings facilitates secure board installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control unit interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required mechanical and environmental specifications. Confirm that the gold plating thickness and contact material align with your application's durability requirements. Ensure the PCB hole pattern corresponds to the 0.100 inch pitch and side-mounting flange dimensions. Check RoHS compliance status if restricted substances are prohibited in your manufacturing process.

Edgeboard Connectors Selection Notes

Choose this component when high-density dual-row connectivity is required for edge cards. The 0.100 inch pitch allows for compact circuit board layouts compared to larger spacing options. Consider the through-hole termination method for robust mechanical stability under vibration. Evaluate the operating temperature range against your environment to ensure long-term reliability of the PBT insulation and metal contacts.

Edgeboard Connectors Part Context

This part belongs to Sullins' MPSL series of edge card connectors, designed for high-reliability applications. The series offers various pin counts and spacing options to accommodate different board densities. The dual female configuration is standard for mating with male edge fingers on daughter cards or modules.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other Sullins models with identical 140-position dual female configurations and 0.100 inch pitch, such as ECC70DRMS-S288, provided mechanical mounting differences are accounted for.
