305-070-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-070-555-503 is a standard card edge connector from the 305 series, designed for dual-edge mating applications. It features 70 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it provides a continuous current rating of 5 A and supports 1800 VACrms insulation voltage. The housing is made of green thermoplastic polyester, ensuring reliable performance in vertical panel mount configurations.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 70-position configuration and dual-edge specification. Confirm compatibility with polarizing key requirements if mechanical locking is necessary for the application. Ensure the target PCB thickness aligns with the 0.062-inch nominal specification to guarantee proper contact engagement. Check RoHS compliance status against current regulatory standards before final procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with 70 positions is required for vertical mounting. The 3.96 mm pitch suits applications needing robust connections with polarizing key support. Consider the 5 A current rating and 1800 VACrms insulation capability for power or signal integrity needs. Verify that the green thermoplastic polyester housing meets environmental temperature ranges for the intended operating conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles, catering to diverse electronic interconnection needs. The 305-070-555-503 variant specifically addresses high-density dual-edge applications, providing a reliable interface solution within the broader EDAC product portfolio for industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations
