387-054-558-258

Edgeboard Connectors Overview

The EDAC Inc. 387-054-558-258 is a single-row female card edge connector from the 387 series, designed for through-hole mounting at a right angle. It features 54 positions with a 0.156-inch (3.96mm) pitch and accepts PCBs with thicknesses between 0.054 and 0.070 inches. The contacts are made of copper alloy with a gold plating thickness of 10.0 microinches. The housing is black thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Single-row female configuration with cantilever contacts for reliable board insertion
• Gold-plated copper alloy contacts ensure durable electrical performance
• Thermoplastic polyester housing provides thermal stability within specified operating range
• Right-angle through-hole termination facilitates standard panel or chassis mounting

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module connections
• Medical device internal circuitry interfaces

Edgeboard Connectors Procurement Notes

Verify the specific pin count and row configuration against the official datasheet to ensure compatibility with the target PCB design. Confirm that the required PCB thickness falls within the specified acceptance range. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the mounting style matches the mechanical constraints of the enclosure.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface with high pin density is required. The 0.156-inch pitch offers a balance between signal count and spacing. Consider the right-angle form factor for space-constrained vertical installations. Verify that the gold contact plating meets the corrosion resistance requirements of the operating environment.

Edgeboard Connectors Part Context
