305-086-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-086-555-212 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 86 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with a thermoplastic polyester insulator body and copper alloy contacts, it utilizes gold plating for reliable signal transmission. The component supports a continuous current rating of 5 A and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body to minimize overall assembly height
• Provides high insulation resistance and robust current carrying capacity

Edgeboard Connectors Applications

• High-density electronic interconnect systems
• Industrial control panels requiring vertical mounting
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and termination styles. Confirm that the thermal and electrical ratings align with the target application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with a 3.96 mm pitch is required for vertical panel mounting. Ensure the host PCB design accommodates the specified 1.57 mm thickness and that the system voltage does not exceed the rated insulation limits.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in handling various board thicknesses and its capability to integrate polarizing keys for enhanced mechanical stability during mating cycles.

Edgeboard Connectors Replacement Considerations

Consult the EDAC official cross-reference documentation for verified substitute part numbers. Do not assume interchangeability with other series without confirming identical pinout, pitch, and mechanical envelope specifications.
