305-052-500-268

Edgeboard Connectors Overview

The EDAC 305-052-500-268 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual female configuration with 52 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The unit supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row receptacle design accommodating non-specified double-sided card edges
• Panel mount installation style with vertical orientation for secure chassis integration
• Gold-plated copper alloy contacts providing corrosion resistance and low contact resistance
• Thermoplastic polyester insulator body ensuring high dielectric strength and thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes requiring robust panel-mounted interconnects
• Telecommunications equipment chassis connecting daughter cards to main systems
• Test and measurement instrumentation utilizing standardized card edge interfaces
• Military and aerospace avionics modules demanding high reliability connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination type. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the panel cutout dimensions align with the connector's flange specifications. Confirm RoHS compliance status if required by project regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for double-sided card edge applications. The 3.96 mm pitch suits designs needing wider spacing between signal lines compared to finer pitches. Consider the 5 A current rating and 105°C operating limit for environmental suitability. Verify that the housing material and contact plating meet the specific electrical and mechanical endurance requirements of the target assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial electronics. The series offers various position counts and mounting styles to accommodate different board densities. The 305-052-500-268 specifically addresses needs for medium-density connections with a focus on durable panel mounting and stable electrical performance over a wide temperature range.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-052-500-202 or 305-052-555-268 for potential substitutes. Verify that alternative parts match the critical parameters: 52 positions, 3.96 mm pitch, dual female configuration, and panel mount style. Ensure any replacement maintains the same PCB thickness tolerance and contact material specifications to guarantee mechanical fit and electrical continuity.
