305-046-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-046-555-258 is a standard card edge connector from the 305 Series, designed for dual female mating with non-specified double-sided PCBs. It features 46 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it utilizes a thermoplastic polyester insulator body rated UL 94V-0. The unit employs a solder pin termination style and supports an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female configuration for reliable connection to double-sided edgeboards
• Gold-plated copper alloy contacts ensure stable signal transmission
• Thermoplastic polyester insulator provides UL 94V-0 flame resistance
• Panel mount vertical installation style facilitates secure board retention

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact tail bend specifications and packaging details. Confirm RoHS compliance status and environmental certifications prior to integration. Ensure that the selected variant matches the required PCB thickness tolerance of 0.062 inches. Cross-reference the part number with official distributor catalogs to validate availability and lead times for production planning.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 46 positions is required for double-sided edgeboards. The 3.96 mm pitch accommodates standard industrial PCB layouts. Consider the vertical panel mount orientation for chassis integration. Verify that the thermal rating up to 105°C meets the operational environment requirements. Ensure compatibility with existing board thickness constraints before finalizing the design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and tail configurations. The series is characterized by its .156 inch contact spacing and low-profile insulator bodies. Similar models in the family include variants with different pin counts such as 305-040 or 305-054, allowing for scalable design solutions within the same mechanical footprint and electrical specification framework.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include 305-040-555-258 and 305-048-520-258, provided the position count difference is acceptable. Verify mechanical dimensions and mounting hole patterns to ensure interchangeability without modifying the host PCB layout.
