305-052-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-507 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 52 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes female half-beehive contacts with gold plating on the mating area and tin plating on tails with nickel underplating. Rated for 5 amps current, it accommodates PCB thicknesses between 1.37 mm and 1.78 mm. The housing is green thermoplastic polyester, and the unit operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure dual-edge card engagement
• Gold-plated mating surfaces ensure reliable electrical conductivity and corrosion resistance
• Thermoplastic polyester insulation provides structural stability across wide temperature ranges
• Panel mount design with solder pin termination for robust mechanical integration

Edgeboard Connectors Applications

• Industrial control system backplanes requiring high-density interconnects
• Telecommunications equipment signal routing modules
• Test and measurement instrument interface cards
• Automotive electronics control unit connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, housing color, and mounting style variations. Ensure the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper contact engagement. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-edge connector is required for panel-mounted applications. The 52-position count suits moderate-density signal routing needs. Consider the 5-amp current rating for power distribution capabilities. Verify that the half-beehive contact type aligns with the mechanical retention requirements of the host system design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various pitch options and mounting configurations for card edge applications. The series is characterized by its robust construction and compatibility with standard industrial connectors. The 305-052-555-507 specifically addresses the need for dual-edge connectivity with a 3.96 mm spacing, fitting into broader system architectures requiring reliable vertical or panel-mounted interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 52 positions and 3.96 mm pitch, such as the 305-052-520-507, provided the mounting style and contact plating requirements are identical. Cross-brand replacements require verification of pitch, row count, and PCB thickness tolerance to ensure mechanical fit and electrical performance equivalence.
