Edgeboard Connectors datasheet and documents for 305-072-520-504

305-072-520-504

Edgeboard Connectors Overview

The EDAC 305-072-520-504 is a standard card edge connector receptacle featuring 72 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) pitch and accepts PCBs with a thickness of 1.57 mm. The contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. Designed for panel mount installation at a straight angle, the housing is constructed from thermoplastic polyester. The component operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure board alignment
Provides high dielectric strength with 1800 VACrms insulation rating
Features semi-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

Industrial control systems requiring robust card edge interfaces
Telecommunications equipment utilizing standardized module connections
Automotive electronics demanding high vibration resistance

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the required polarizing key configuration matches the design intent, as these connectors support both between-contact and in-contact options. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 72-position interface is required for thick PCB applications. The 3.96 mm pitch accommodates standard board layouts while the 5 A rating supports moderate power distribution. Consider the panel mount style for chassis integration rather than direct PCB mounting. Verify that the operating temperature range meets environmental requirements and that the gold plating thickness satisfies long-term cycle life expectations.
