305-018-556-508

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-508 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features an 18-position dual-row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are made of copper alloy with gold plating, rated for 5 A current at an insulation resistance of 5 GOhms. The thermoplastic insulator body supports an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating two rows of contacts
• Low-profile thermoplastic insulator body construction
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel-mount vertical installation style

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation with high-reliability requirements
• Automotive electronics modules needing durable thermal performance

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the official EDAC ordering guide to confirm exact termination type and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times. Confirm RoHS compliance details if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 18-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing between signal lines compared to finer pitches. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry. Ensure the operating temperature range aligns with the environmental conditions of the intended deployment location.
