305-042-556-507

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-507 is a standard card edge connector from the 305 series, designed for dual-edge board mating. It features 42 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes gold plating on the mating area and tin plating with nickel underplating on the tails. The unit has a current rating of 5 amps and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density signal routing
• Low-profile insulator body construction
• Panel mount style with threaded insert flange

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel mounting
• Telecommunications equipment interfaces
• Test and measurement instrumentation backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the presence of threaded inserts and the exact flange diameter. Ensure the target PCB thickness aligns with the 0.062-inch nominal specification to guarantee proper mechanical retention. Confirm that the dual-edge mating requirement matches the system design before procurement.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution with high positional count is required. The 3.96 mm pitch distinguishes it from finer-pitch alternatives. Consider the threaded flange feature if vibration resistance and secure panel attachment are critical operational requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors. The series offers various position counts and mounting styles. The 305-042 variant specifically provides 42 contacts, balancing density with manageable physical footprint for standard industrial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 42-position counts and dual-edge specifications. Verify that alternative options maintain the same 3.96 mm pitch and panel-mount flange dimensions to ensure mechanical compatibility.
