305-024-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-024-521-258 is a standard card edge connector from the 305 series, designed for panel and through-hole mounting. It features 24 positions with a dual female configuration and a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts with a half-bead termination type and solder pin end connections. Rated for 5 A current, it accommodates printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The insulator is constructed from green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch specifications before procurement. Confirm compliance with RoHS3 and REACH regulations as indicated in official documentation. Ensure that the selected variant aligns with the intended mounting style and board thickness requirements. Cross-reference manufacturer datasheets to validate environmental ratings and material compositions against project constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with 0.156-inch spacing is required for robust industrial environments. Consider the 5 A current rating and wide temperature range for demanding applications. Evaluate the panel mount option if space constraints favor overboard insertion. Compare alternative series within the same family only if different position counts or termination styles are necessary.
