857-080-556-204

Edgeboard Connectors Overview

The EDAC Inc. 857-080-556-204 is a high-temperature standard card edge connector designed for robust electronic interconnections. It features 80 positions with dual female contacts, utilizing gold plating on copper alloy terminals to ensure reliable signal transmission. The component employs a 3.96 mm (0.156 inch) contact spacing and a 5.08 mm (0.200 inch) row spacing. It accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes a low-profile insulator body constructed from thermoplastic polyester, providing durability in demanding environments.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet environmental standards for your region. Confirm that the dual-edge female gender matches the mating card specifications.

Edgeboard Connectors Selection Notes

Select this model when high-temperature performance is critical for the application environment. The 80-position capacity supports complex signal routing needs within a defined footprint. The 3.96 mm pitch offers a balance between density and manufacturability. Consider the panel mount or straddle mount options if mechanical stability during operation is required. Verify that the gold plating meets the specific wear requirements of the mating cycle.
