307-034-441-101

Edgeboard Connectors Overview

The EDAC Inc. 307-034-441-101 is a standard card edge connector from the 307 series, designed for dual-edge board applications. It features 68 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 5.08 mm. The connector accepts PCBs with a nominal thickness of 1.57 mm, specifically ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). It utilizes copper alloy contacts with tin plating and is housed in green thermoplastic polyester insulation. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified dual-edge cards
• Semi-bellows contact type ensures reliable engagement with card edges
• Panel mount installation style with flange features including top opening and threaded inserts

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing dual-edge circuit boards
• Test and measurement instrumentation needing high-density connections

Edgeboard Connectors Procurement Notes

Verify that the specific application requires a dual-edge card interface rather than single-edge alternatives within the 307 series. Confirm that the PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mechanical fit. Ensure the tin-plated contacts meet the environmental requirements, as gold-plated variants exist in this series for different corrosion resistance needs. Check for any specific flange thread requirements corresponding to the 4-40 threaded inserts if mounting hardware compatibility is critical.

Edgeboard Connectors Selection Notes

Select this part when a high-pin-count (68 position) dual-edge connection is necessary for panel mounting. The 3.96 mm pitch allows for substantial signal routing density compared to finer pitches. Consider the tin plating for cost-effective solutions where extreme corrosion resistance is not the primary driver, unlike the gold-plated options available in the same series. The vertical orientation and panel mount style dictate the enclosure integration strategy.

Edgeboard Connectors Part Context

This component belongs to the EDAC 307 series, which specializes in card edge connectors with a 3.96 mm contact spacing. The series offers various configurations including single and dual rows, different mounting styles, and contact plating options. The 307-034-441-101 specifically addresses the need for dual-edge connectivity with a high position count, distinguishing it from single-edge headers or lower-position variants in the lineup.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 307 series parts with matching 68 positions and dual-edge specifications, such as 307-034-441-107, provided the contact plating difference (tin vs. gold) is acceptable for the application environment.
