305-052-500-503

Edgeboard Connectors Overview

The EDAC Inc. 305-052-500-503 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 52 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row pitch. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts gold-plated for conductivity, it utilizes a green thermoplastic insulator body. Rated for 5 A continuous current, it supports panel mounting with solder lug termination.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm pin count, plating, and termination type match project requirements. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure PCB thickness falls within the specified acceptance range to guarantee proper mechanical engagement and electrical continuity during operation.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 52 positions is required on a dual-edge board. The 3.96 mm pitch accommodates larger traces compared to finer pitches. Verify that the panel mounting style and solder lug termination are compatible with the enclosure design and manufacturing process constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and termination options. The 305-052 variant specifically provides a 52-position interface, balancing density with the robust 3.96 mm spacing suitable for industrial environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for different position counts. Verify compatibility with polarizing keys if board orientation locking is required. Check datasheets for alternative termination styles such as solder pins or wire holes.
