305-070-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-070-556-207 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 70 positions and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It is specified as a dual-edge female header compatible with non-specified card types. The unit supports a current rating of 5 A and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for board-to-board or backplane interconnection
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance
• Straddle mount installation style provides secure panel attachment
• Vertical orientation facilitates compact circuit board layout

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact finish thickness and insulation material properties. Ensure that the selected variant matches the required card thickness specifications and mounting hole dimensions for your enclosure design. Cross-reference the RoHS compliance status with current regulatory requirements for your target market before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 70-position interface is required for vertical panel mounting. The 3.96 mm pitch accommodates standard double-sided PCBs. Consider the 5 A current rating for power distribution needs alongside signal lines. Verify that the straddle mount style aligns with your chassis design constraints and that the gold plating meets environmental durability standards for the intended operating conditions.
