305-026-556-207

Edgeboard Connectors Overview

The EDAC Inc. 305-026-556-207 is a standard card edge connector from the 305 series, designed for dual female board-to-board connections. It features 26 positions 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), falling within an acceptable range of 1.37 mm to 1.78 mm. Constructed with copper alloy contacts featuring gold plating and a thermoplastic insulator, it supports solder lug termination. Rated for 5 A current at +105°C maximum operating temperature, it provides reliable vertical panel mounting.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 26-position count and dual-row configuration before procurement. Confirm compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit. Check for RoHS compliance requirements if environmental regulations apply to the final assembly. Ensure the solder lug termination type aligns with the available manufacturing processes for the host circuit board design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm spacing is necessary for vertical panel installation. Consider the 5 A current rating and +105°C temperature limit against the application's thermal profile. Evaluate the need for gold-plated contacts to minimize contact resistance in critical signal paths. Compare alternative positions within the 305 series if the pin count does not match the specific design requirements.
