305-072-555-512

Edgeboard Connectors Overview

The EDAC Inc. 305-072-555-512 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts non-specified dual-edge cards with thicknesses ranging from 1.37 mm to 1.78 mm. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A and an insulation resistance of 5 GOhms. Designed for PCB mounting at a straight angle, the housing is made of green thermoplastic polyester. The component operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure card retention
• Provides high dielectric strength with a 1800VACrms voltage rating
• Features gold-plated half-beam spring contacts for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing modular board architectures
• Automotive electronics applications demanding high vibration resistance

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and contact plating specifications. Confirm that the target printed circuit board thickness falls within the accepted range of 1.37 mm to 1.78 mm prior to procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Ensure that the selected variant matches the required mounting style and terminal type for the assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 72 positions is required for high-density interconnects. The 3.96 mm pitch allows for standard board spacing while maintaining signal integrity through gold-plated contacts. Consider the 5 A current rating and 1800VACrms insulation capability for power and signal distribution needs. The straight PCB mount orientation suits applications where space constraints dictate a perpendicular connection profile relative to the mating card.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, designed for general-purpose electronic interconnections. The series offers various position counts and row configurations to accommodate different board sizes. The 305 series is characterized by its durable thermoplastic polyester housing and consistent 3.96 mm pitch across multiple variants. It serves as a reliable solution for connecting plug-in boards in industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 72-position dual-row layouts and matching 3.96 mm pitch. Verify mechanical dimensions and flange characteristics against the original design to ensure panel fit. Alternative manufacturers may offer compatible connectors if pinout, current rating, and thermal specifications align with the system requirements.
