305-050-521-508

Edgeboard Connectors Overview

The EDAC 305-050-521-508 is a standard card edge connector featuring 50 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a row spacing of 3.56 mm (0.140 inch). Designed for panel mounting, this vertical header accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, 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 board alignment
• Features a low-profile insulator body made of thermoplastic material
• Provides high dielectric strength with 1800 VACrms insulation rating

Edgeboard Connectors Applications

• Medical interconnect systems requiring robust connection stability
• Agricultural technology equipment operating in harsh environments
• Industrial control panels utilizing standard card edge interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, pitch, and termination style match the design requirements. Confirm RoHS compliance status and moisture sensitivity level before integration. Ensure the selected variant supports the required PCB thickness tolerance and mounting flange specifications for the target enclosure.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 3.96 mm pitch is required for panel-mounted applications. Verify that the host system accommodates the specified 1.57 mm board thickness and that the 5 A current rating meets the electrical load demands. Consider the availability of polarizing keys if mechanical locking is necessary for the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations designed for reliable interconnection in demanding industrial and medical sectors. The 305 series is characterized by its durable thermoplastic housing and gold-plated contacts suitable for repeated mating cycles.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with different position counts or row configurations. Direct substitutes must maintain identical 3.96 mm pitch and dual-row geometry to ensure mechanical compatibility.
