357-040-501-104

Edgeboard Connectors Overview

The EDAC Inc. 357-040-501-104 is a standard card edge connector from the 357 series, designed for reliable signal transmission in electronic assemblies. This component features 80 positions arranged in a dual-edge configuration with a female contact type. It utilizes a 3.96 mm (0.156 inch) pitch and supports a board thickness of 1.57 mm. The contacts are gold-plated copper alloy, ensuring durability and low resistance. The unit employs through-hole termination with solder eyelets for secure PCB mounting. Operating within a temperature range of -40°C to 105°C, it includes flanges for alignment and stability during installation.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating two-sided card edge interfaces
• Gold-plated copper alloy contacts providing corrosion resistance and stable conductivity
• Through-hole solder eyelet termination method for robust mechanical attachment
• Integrated flange structure facilitating precise alignment and secure positioning

Edgeboard Connectors Applications

• Industrial control system backplanes requiring high-density interconnects
• Medical equipment internal circuit boards demanding reliable signal paths
• Agricultural technology hardware operating in harsh environmental conditions
• General-purpose electronic modules utilizing standard card edge form factors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, plating thickness, and flange configuration. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before procurement. Confirm that the through-hole solder eyelet termination matches the assembly process capabilities. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet project-specific environmental standards.

Edgeboard Connectors Selection Notes

Select this model when a high-position-count interface is required for dual-sided card edge applications. The 3.96 mm pitch offers a balance between density and manufacturability for larger boards. Consider the gold plating for environments where oxidation resistance is critical. The vertical mounting angle and flanged design simplify assembly alignment compared to unflanged variants. Evaluate thermal requirements against the specified -40°C to 105°C operating range to ensure suitability for the intended application environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 357 series of standard card edge connectors, which provides a comprehensive range of options for various position counts and termination styles. The series is engineered for durability and reliability across multiple industries, including medical and agricultural sectors. The 357-040-501-104 specifically addresses needs for high-pin-count connections with dual-edge access, offering a standardized solution for complex electronic interconnections within the broader EDAC product portfolio.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and termination but different position counts, such as the 357-030-527-104 or 357-022-531-104, if fewer positions suffice. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure the alternative part retains the dual-edge female configuration and gold-plated contacts to preserve electrical and mechanical performance characteristics.
