305-044-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-507 is a dual-edge female card edge connector with 44 positions arranged in two rows of 22 contacts each. It features a 0.156-inch (3.96 mm) pitch and accepts non-specified dual-edge cards within a thickness range of 0.054 to 0.070 inches. The connector utilizes gold-plated half-bevel contacts for reliable signal transmission and is constructed with a green thermoplastic polyester insulator. Designed for panel mounting via through-hole solder termination, it includes flange features with top openings and M3 threaded inserts for secure installation.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration designed for robust connection with non-specified double-sided circuit boards
• Gold-plated half-bevel contacts ensure durable electrical performance and low contact resistance
• Panel mount construction with integrated flange featuring top openings and threaded inserts for mechanical stability

Edgeboard Connectors Applications

• Industrial control systems requiring high-density I/O connections
• Telecommunications equipment backplanes and interface modules
• Test and measurement instrumentation board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact flange and plating specifications. Ensure compatibility with the target PCB stack-up and card thickness requirements before procurement. Confirm RoHS compliance status matches project regulatory needs. Cross-reference the manufacturer part number with distributor listings to validate current availability and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel-mounted applications. The 44-position count suits moderate density interfaces. Verify that the M3 threaded insert flange design aligns with the chassis mounting constraints. Ensure the operating temperature range of -40°C to 105°C meets environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles. The 305-044 variant specifically provides a mid-range contact count suitable for general-purpose industrial and commercial electronic assemblies requiring reliable board-to-panel connectivity.

Edgeboard Connectors Replacement Considerations

The 355-044-521-507 is a similar 44-position dual-edge connector from the same manufacturer but differs in housing color and potentially minor mechanical details. Verify dimensional drawings and flange specifications before substitution to ensure mechanical fit.
