305-042-500-278

Edgeboard Connectors Overview

The EDAC 305-042-500-278 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 42 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector accepts PCBs with a nominal thickness of 1.57 mm and supports a continuous current rating of 5 A. Contacts are made of copper alloy with gold plating, utilizing a solder lug termination type. The housing is constructed from thermoplastic material, providing an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations and PCB thickness tolerances. Confirm that the selected variant matches the necessary current rating and environmental operating range for the target application. Cross-reference the manufacturer's latest datasheet to validate pinout and mechanical dimensions before integration into the design.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. Ensure the host PCB thickness falls within the specified tolerance range to guarantee proper contact engagement. Consider the 5 A current rating and thermal operating limits when designing the circuit layout and enclosure ventilation.
