837-022-556-202

Edgeboard Connectors Overview

The EDAC Inc. 837-022-556-202 is a standard card edge connector featuring 22 positions with a 3.96 mm (0.156 inch) contact spacing. It utilizes gold-plated copper alloy contacts and a green Diallyl Phthalate (DAP) insulator housing. Designed for straddle mount installation at a vertical angle, this dual-edge connector supports a PCB thickness of 1.57 mm. The component belongs to the 837 High Temp series, offering reliable electrical connectivity for board-to-board applications.

Edgeboard Connectors Feature Summary

• Dual-edge configuration for secure board engagement
• Gold-plated contacts ensure corrosion resistance
• High-temperature resistant DAP insulator material
• Straddle mount style for stable vertical positioning

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature stability
• Telecommunications equipment board connections
• Automotive electronics interfaces
• Aerospace and defense circuit assemblies

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, plating thickness, and mounting style variations. Ensure compatibility with the target PCB edge thickness and slot dimensions before procurement. Cross-reference the part number with authorized distributors to confirm availability and lead times, as supply chain status may vary by region.

Edgeboard Connectors Selection Notes

Select this connector when a vertical, straddle-mount interface is required for double-sided card edges. The 3.96 mm pitch accommodates standard industrial board layouts. Verify that the operating environment temperature exceeds standard limits, as the DAP housing provides necessary thermal stability. Confirm that the application does not require surface mount or right-angle configurations.

Edgeboard Connectors Part Context

This component is part of the EDAC 837 High Temperature Series, designed for demanding environments where standard materials may degrade. The series offers various position counts and termination styles. The 837-022-556-202 specifically addresses needs for moderate-density connections with robust mechanical retention in vertical orientations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 837 models with matching 22-position counts and straddle mount styles. Verify equivalent contact spacing and housing material properties. Alternative manufacturers may offer similar specifications but require verification of dimensional tolerances and electrical ratings.
