305-070-500-504

Edgeboard Connectors Overview

The EDAC Inc. 305-070-500-504 is a dual-edge female card edge connector designed for board-to-board interconnection. It features 70 positions arranged in two rows with a 0.156-inch (3.96 mm) pitch. The contacts are gold-plated copper alloy half-beam spring type, providing a continuous current rating of 5 A and an insulation voltage of 1800 VAC rms. The housing is green thermoplastic polyester, rated for operation between -40°C and 105°C. It supports PCB thicknesses from 0.054 to 0.070 inches and accepts polarizing keys.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with gold-plated half-beam spring contacts for reliable signal transmission
• Accepts between-contact and in-contact polarizing keys for secure board alignment
• High-voltage insulation capability with 1800 VAC rms rating and 5 A continuous current capacity
• Green thermoplastic polyester housing compatible with standard panel mount installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing high-density signal routing
• Medical devices needing reliable vertical interconnects
• Automotive electronics operating in varied thermal environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct contact termination and flange characteristics. Confirm that the required polarizing key style matches the connector's acceptance specifications. Check RoHS compliance status and MSL classification prior to assembly planning. Ensure PCB design accommodates the specified 0.156-inch pitch and dual-row layout constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface with a 3.96 mm pitch is required. The 5 A current rating and 1800 VAC insulation make it suitable for power and signal distribution in industrial settings. Consider the half-beam contact type for mating force requirements. Verify that the target PCB thickness falls within the 0.054 to 0.070 inch range for proper mechanical engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-070 variant specifically provides 70 positions. The product line is characterized by durable thermoplastic housings and gold-plated contacts. It is widely used in applications demanding stable electrical connections under mechanical stress.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series parts using the official EDAC ordering guide for equivalent pin counts or pitch variations. Verify compatibility with existing polarizing key systems if substituting with different suffix variants. Ensure replacement parts maintain the same 0.156-inch pitch and dual-edge female configuration.
