305-042-555-212

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-212 is a standard card edge connector from the 305 series, designed for dual-edge board applications. 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-plated copper alloy contacts and a green thermoplastic polyester insulator body. Rated for 5 A continuous current and 1800 VACrms dielectric voltage, it supports a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features a low-profile insulator body suitable for space-constrained designs
• Provides high dielectric strength rated at 1800 VACrms

Edgeboard Connectors Applications

• Card extender modules requiring dual-edge connectivity
• High-temperature electronic assemblies operating up to 105°C
• Industrial control systems utilizing polarized card edge interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 42-position configuration and dual-row layout. Confirm compatibility with the target PCB thickness of 0.062 inches (1.57 mm) to ensure proper mechanical fit. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the application environment remains within the specified -40°C to +105°C operational temperature range.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connector with 0.156-inch pitch is required for vertical panel mounting. It is appropriate for designs needing polarizing key support to prevent misalignment during insertion. Consider this model for applications demanding a 5A current rating and robust insulation properties. Verify that the straddle mount style aligns with the chassis or panel design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in accepting various polarizing keys and its suitability for both single and double-sided board connections. The 305 series provides reliable electrical performance with gold-plated contacts and durable thermoplastic housings.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-042-520-202 and 305-042-520-212. These alternatives share identical pin counts and spacing but may differ in termination type or housing color. Verify that any replacement maintains the required 0.156-inch pitch and dual-row configuration.
