305-012-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-012-521-558 is a standard card edge connector from the 305 Series, designed for dual female board-to-board interconnection. It features 12 positions with a 0.156-inch (3.96 mm) pitch and accepts PCBs with thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and half-bead contact types. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Accepts between-contact and in-contact polarizing keys
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Medical interconnect solutions
• Agricultural technology equipment
• Industrial control systems
• General electronic board-to-board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, contact plating specifications, and mounting style compatibility. Ensure that the target printed circuit board thickness falls within the specified acceptance range of 0.054 to 0.070 inches to guarantee proper mechanical engagement and electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel-mounted applications. Confirm that the design accommodates the necessary polarizing key slots if signal isolation is needed. Verify that the operating environment remains within the -40°C to +105°C temperature range and that the 5 A current rating meets the circuit requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides robust card edge connectors for demanding environments. The series supports various position counts and mounting configurations, catering to diverse industrial and commercial needs. The 305-012-521-558 specifically offers a 12-position dual-edge solution with green thermoplastic polyester insulation.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with different position counts or contact configurations. Direct substitutes must maintain the same 3.96 mm pitch, dual-edge female interface, and panel mount style to ensure mechanical fit.
