305-044-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-501 is a standard card edge connector designed for dual-edge board applications. It features a 44-position configuration with a 0.156-inch (3.96mm) pitch across two rows. The connector utilizes female half-bellows contacts with gold plating to ensure reliable signal transmission. It supports PCB thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C. The housing is constructed from green thermoplastic polyester, providing durability and insulation.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for simultaneous connection on both sides of the card edge
• Gold-plated half-bellows contacts designed for secure mating and low contact resistance
• Thermoplastic polyester insulator housing offering thermal stability and mechanical strength
• Panel mount installation with flush flange characteristics for secure board retention

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnect solutions
• Medical equipment interfaces demanding high reliability
• Agricultural technology hardware exposed to harsh environments
• General-purpose electronic assemblies utilizing dual-edge card architectures

Edgeboard Connectors Procurement Notes

Verify that the specific application environment aligns with the component's operating temperature range of -40°C to 105°C. Confirm that the PCB thickness falls within the specified 0.054 to 0.070 inch limit to ensure proper contact engagement. Ensure that the mounting method matches the flush flange design requirements. Cross-reference the official datasheet for precise mechanical dimensions before finalizing the bill of materials.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with a 0.156-inch pitch is required for 44 signals. Consider the gold-plated half-bellows contacts for applications needing durable mating cycles. Evaluate the panel mount style against available space constraints. Compare the thermoplastic polyester housing properties against other material options if extreme chemical exposure is anticipated.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is engineered for standard card edge applications, providing consistent performance across different position counts. The 305-044 variant specifically addresses higher density needs while maintaining the established pitch and contact geometry of the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 44-position dual-edge specifications. Verify compatibility by checking pitch, contact type, and mounting style. Alternative manufacturers may offer similar connectors, but mechanical fit and electrical ratings must be validated against the original datasheet.
