305-066-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-066-555-508 is a standard card edge connector from the 305 series, designed for dual-edge board connections. It features 66 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector supports nominal PCB thicknesses of 1.57 mm (0.062 inches) and utilizes gold-plated copper alloy contacts. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic, and it employs a straddle mount installation style.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density signal routing
• Gold-plated contacts ensure reliable conductivity
• Straddle mount design for secure panel attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific pin count and mounting style against your PCB layout requirements before ordering. Confirm that the target printed circuit board thickness aligns with the connector's acceptance range of approximately 1.57 mm. Ensure that the straddle mount footprint matches your assembly capabilities. Cross-reference the manufacturer part number with official distributor catalogs to confirm current availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for thicker PCBs up to 1.57 mm. The 3.96 mm pitch offers reduced density compared to finer pitches but provides mechanical stability. Consider the straddle mount option if panel mounting is preferred over board edge insertion. Verify that the 5 A current rating meets the electrical load requirements of the application circuits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, including vertical and horizontal options. The 305 series is characterized by its low-profile insulator body and compatibility with non-specified dual-edge cards. It serves as a modular solution for connecting edgeboard modules to system backplanes in industrial environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with identical pitch and row spacing but different position counts, such as the 305-018-555-508 or 305-048-556-508. Ensure any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness tolerance. Verify that the mounting style remains consistent to avoid PCB layout modifications.
