305-012-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-012-521-207 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 12 positions with a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes copper alloy contacts with gold plating and offers a 5 A current rating and 1800 VACrms insulation voltage. It employs solder pin termination for panel mounting.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual female contact configuration for reliable signal transmission
• Gold-plated half-beam spring contacts ensure low resistance connection

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 12-position configuration and 3.96 mm pitch before procurement. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment does not exceed the specified 105°C operating temperature or 1800 VACrms dielectric strength limits. Cross-reference the manufacturer's ordering guide for any updated suffix designations.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required. It is suitable for applications needing polarizing key acceptance and a 5 A continuous current rating. Consider the vertical panel mount style and green thermoplastic polyester housing for environmental durability. Verify that the solder pin termination method aligns with the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles for general-purpose electronic interconnects. The 305-012-521-207 variant specifically addresses needs for 12-position dual-edge connections with robust electrical ratings.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for confirmed substitute part numbers. Verify that any replacement maintains the 3.96 mm pitch, 12-position count, and dual-edge female contact type. Ensure mechanical dimensions and mounting specifications match the existing design constraints.
