305-052-520-512

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-512 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a dual female configuration providing 52 positions across two rows, utilizing a 3.96 mm (0.156 inch) pitch. The connector accepts PCBs with a thickness range of 1.37 mm to 1.78 mm (0.054" to 0.070"). Constructed with copper alloy contacts and thermoplastic polyester insulation, it offers a continuous current rating of 5 A and supports 1800 VACrms dielectric voltage. The contacts are gold-plated with a thickness of 10.0 µin (0.25 µm) and utilize a half-beam spring contact type for reliable solder pin termination.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarization keys and board thickness specifications. Confirm that the thermal and electrical ratings align with the target application environment. Cross-reference the RoHS status and material composition requirements with project compliance standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge interface is required for double-sided PCBs. Ensure the host system accommodates the specified 3.96 mm pitch and vertical mounting constraints. Validate that the operating temperature range of -40°C to 105°C meets environmental demands. Consider the availability of compatible polarizing keys if mechanical locking or alignment is necessary for the assembly process.
