305-066-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-066-500-258 is a standard card edge connector from the 305 Series, designed for panel-mounted applications. It features a dual-row configuration with 66 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes semi-bellows contact types with gold plating on copper alloy terminals to ensure reliable signal transmission. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Semi-bellows contact design ensures positive mating force and reliable connection stability
• Gold-plated copper alloy contacts provide corrosion resistance and low contact impedance
• Low-profile insulator body constructed from thermoplastic material for compact integration
• Panel mount installation style with vertical orientation for secure board attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnect solutions
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-reliability panel connections
• Automotive electronics operating in extended temperature environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, row configuration, and termination type. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the RoHS status and environmental ratings with project requirements. Confirm availability through authorized distributors as supply chains may vary. Validate that the panel mounting flange features match the mechanical enclosure design constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for panel-mounted installations. The semi-bellows contact type offers superior retention compared to standard finger contacts, making it suitable for vibration-prone environments. Consider the 66-position capacity and green insulator color for visual identification. Ensure the application does not require higher current ratings or different board thicknesses than specified in the official documentation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are widely used in industrial and commercial electronic assemblies. The series offers various position counts and mounting styles to accommodate diverse design needs. The 305-066-500-258 specifically addresses applications requiring a 66-position interface with robust mechanical locking via its panel mount design.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configuration but different position counts, such as the 305-050-500-202. Verify mechanical dimensions and electrical ratings before substituting. No other manufacturers' direct equivalents are confirmed in public documentation.
