305-046-556-268

Edgeboard Connectors Overview

The EDAC Inc. model 305-046-556-268 is a standard card edge connector designed for panel mounting applications. It features a dual female configuration with 46 positions arranged in two rows. The contact spacing is 3.96 mm (0.156 inches), and the row spacing is 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy and finished with gold plating to ensure reliable electrical performance. The housing is made of thermoplastic material, providing structural integrity and insulation.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, plating thickness, and housing color specifications. Ensure that the target application PCB thickness aligns with the 1.57 mm nominal requirement for proper mechanical engagement. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 46 positions is required for panel-mounted systems. The 3.96 mm pitch accommodates standard board layouts while maintaining signal integrity. Consider the vertical mounting angle and thermoplastic housing durability for environments requiring robust mechanical retention and long-term thermal stability up to 105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for high-reliability interconnect solutions. The series offers various position counts and mounting configurations to support diverse electronic assembly needs. The 305-046-556-268 variant specifically addresses applications requiring a 46-position dual-edge connection with panel-mount flexibility and durable contact materials.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include EDAC models 305-040-556-268 and 305-054-556-268, which share identical pitch, mounting style, and contact specifications but differ in position count. Verify dimensional compatibility with existing chassis cutouts before substitution.
