306-018-420-102

Edgeboard Connectors Overview

The EDAC Inc. 306-018-420-102 is a standard card edge connector receptacle featuring 18 positions with a 3.96 mm (0.156 inch) contact spacing. It utilizes a single centerline row design and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts for reliable signal transmission and is housed in a green thermoplastic polyester insulator body. Designed for panel mount installation, it offers vertical orientation to facilitate secure board connections.

Edgeboard Connectors Feature Summary

• Single centerline row configuration for standardized card edge interface
• Gold-plated copper alloy contacts ensure durable electrical connectivity
• Thermoplastic polyester insulator provides stable mechanical support

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating and material specifications, as variations exist within the 306 series. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the single-row receptacle format aligns with the assembly requirements. Cross-reference the manufacturer datasheet for precise dimensional tolerances and mounting hole patterns to prevent integration errors during production.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, single-row connection is required for 1.57 mm thick boards. The 3.96 mm pitch suits applications where space efficiency is balanced with robust contact retention. Verify that the vertical panel mount style fits the enclosure constraints. Consider the gold plating for environments requiring corrosion resistance and repeated mating cycles compared to tin-plated alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, designed for high-reliability interconnect solutions. The series supports various position counts and mounting styles, catering to diverse industrial and commercial electronics needs. The 306-018 variant specifically addresses applications requiring 18 channels with a 0.156-inch pitch, offering a compact footprint for dense circuit layouts.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 306 series parts with matching 18-position and 3.96 mm pitch specifications. Verify that alternative components maintain the same 1.57 mm board thickness acceptance and vertical panel mount orientation. Ensure contact plating and insulator material properties meet or exceed the original performance standards.
