305-012-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-012-555-558 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 12 positions with a 3.96 mm (0.156 inch) pitch and supports a maximum PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. Rated for 5 A current, it employs a solder lug termination type for secure panel mounting. The housing is constructed from thermoplastic material, providing structural integrity across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact plating thickness and housing color variants. Ensure that the receiving facility's inventory management systems are updated with the correct RoHS compliance documentation prior to acceptance. Cross-reference the part number with official distributor catalogs to confirm current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and gold-plated contacts make it suitable for environments demanding stable electrical performance. Verify that the target PCB thickness aligns with the 1.57 mm specification to ensure proper mechanical engagement and contact retention.

Edgeboard Connectors Part Context
