337-022-540-207

Edgeboard Connectors Overview

The EDAC Inc. 337-022-540-207 is a standard card edge connector socket featuring 22 positions arranged in a dual row configuration. It utilizes a 3.96 mm pitch and is designed for vertical through-hole mounting with wire wrap termination. The contacts are gold-plated copper alloy, rated for 3 A current, while the thermoplastic polyester housing supports an operating temperature range of -40°C to +105°C. Insulation resistance is specified at 5 GOhms, and it accommodates a board thickness of 1.57 mm.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density interconnect applications
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Vertical through-hole installation with wire wrap termination style
• Thermoplastic polyester insulation provides thermal stability up to 105°C

Edgeboard Connectors Applications

• Medical interconnect solutions including ventilators and CPAP machines
• Ambulance communication and monitoring systems
• Hospital room medical equipment connections

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number 337-022-540-207 with official EDAC documentation. Confirm that the specific suffix matches the required flange features, such as flush mount or threaded inserts, as these variations affect mechanical compatibility. Ensure the supplier provides valid traceability records for the copper alloy contacts and gold plating specifications before finalizing acquisition.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row card edge interface with a 3.96 mm pitch is required for vertical PCB integration. The wire wrap termination style necessitates compatible PCB pad layouts. Verify that the target application operates within the specified -40°C to +105°C temperature range and does not exceed the 3 A current rating per contact. Ensure the mating card edge thickness aligns with the 1.57 mm design specification.

Edgeboard Connectors Part Context

This component belongs to the EDAC 337 series of standard card edge connectors. The series offers various position counts and row configurations, utilizing consistent 3.96 mm pitch dimensions across models. The 337-022-540-207 variant specifically addresses dual-row requirements with 22 positions, distinguishing it from single-row counterparts like the 337-026-558-112 model.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants with different position counts or row configurations, such as the 337-044-540-201. Verify mechanical fit and electrical ratings before substitution. No alternative manufacturers produce identical pin-compatible replacements for this specific proprietary EDAC form factor.
