305-050-555-512

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-512 is a standard card edge connector from the 305 series, designed for dual female connections with 50 positions. It features a 3.96 mm (0.156 inch) pitch and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The unit supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C. Constructed with thermoplastic polyester insulation, it accommodates board thicknesses between 1.37 mm and 1.78 mm. This component employs a solder termination method and is suitable for non-specified dual-edge card applications.

• Gold-plated copper alloy contacts ensure durability and low contact resistance.
• Thermoplastic polyester housing offers thermal stability and mechanical strength.
• Accepts between-contact and in-contact polarizing keys for secure alignment.

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Computer peripheral interface boards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and pitch specifications before integration. Confirm compliance with RoHS3 directives if environmental regulations apply to the assembly. Ensure the receiving facility handles electrostatic discharge precautions during storage and installation. Cross-reference the datasheet for accurate dimensional tolerances to guarantee proper fit within the designated chassis or panel mount enclosure.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge female interface with a 3.96 mm pitch is required. The 50-position layout suits high-density signal routing needs. Consider the 5 A current rating for power distribution capabilities. Verify compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. The vertical mounting style and solder termination method define the assembly process requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which provides a range of card edge connectors with varying position counts and mounting styles. The series is characterized by its robust construction and standardized 3.96 mm spacing. These connectors are widely used in environments requiring reliable electrical connections for edge-board modules. The 305-050-555-512 variant specifically addresses the need for a 50-position dual-row interface.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-050-556-502 and 305-050-556-201. These alternatives share identical electrical characteristics and positioning but may differ in flange features or specific packaging configurations. Verify mechanical dimensions and termination types before swapping components to ensure physical compatibility.
