EMM12DRKN

Edgeboard Connectors Overview

The EMM12DRKN is a card edge connector manufactured by Sullins Connector Solutions. It features 24 contacts arranged in two rows with a straight orientation and a 0.156-inch pitch. The receptacle utilizes solder terminals and includes locking mechanisms for secure installation. Constructed with phosphor bronze contacts and gold over nickel plating, it offers a contact resistance of 10 mΩ and withstands 1800VDC dielectric voltage. The insulator is made of glass-filled polybutylene terephthalate, supporting an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with bellowed contact style for reliable signal transmission
• Integrated locking mechanism ensures secure board retention during operation
• Gold over nickel plating on phosphor bronze contacts provides corrosion resistance
• Glass-filled PBT insulator supports high-temperature environments up to 125°C

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics motherboard connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation when ordering, as variants like EMM12DRKN-S13 may exist within the product line. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to finalizing procurement plans. Ensure that the selected variant matches the required mounting orientation and locking features for the target application.

Edgeboard Connectors Selection Notes

Select this component for applications requiring dual-edge card insertion with a 0.156-inch pitch. The locking feature distinguishes it from non-locking counterparts, providing enhanced mechanical stability. Consider the through-hole termination method and the specific contact material properties when evaluating compatibility with the printed circuit board design and environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EMM series of card edge connectors from Sullins Connector Solutions. The series is designed for general-purpose interconnect applications requiring robust mechanical connection. The EMM12DRKN specifically addresses needs for dual-edge cards with locking capabilities, differentiating it from standard receptacles without retention features.

Edgeboard Connectors Replacement Considerations

Direct substitutes include models such as ESM12DRSS and EBM12DRUI from the same manufacturer, which share similar electrical characteristics and pin counts but differ in flange features and mounting options. Verify physical dimensions and locking mechanisms before substitution.
