895-138-541-512

Edgeboard Connectors Overview

The EDAC Inc. 895-138-541-512 is a standard card edge connector receptacle featuring 138 positions arranged in a dual-row configuration with a 0.100" (2.54mm) pitch and 0.200" (5.08mm) row spacing. Designed for vertical panel mount installation, it utilizes wire wrap termination and gold-plated copper alloy contacts rated for 3A current. The insulator body is constructed from black polyphenylene sulfide (PPS), supporting PCB thicknesses of approximately 1.57mm. It operates within a temperature range of -40°C to +125°C and includes side mount flange openings.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified double-sided circuit boards
• High-profile PPS insulator body provides structural stability and thermal resistance
• Wire wrap termination ensures reliable electrical connections without soldering
• Side-mounted flange features facilitate secure panel integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-panel connectivity
• Telecommunications infrastructure equipment
• Medical device internal module interconnections
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact flange dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57mm nominal. Confirm that the wire wrap termination method aligns with the assembly process capabilities. Check for any recent product change notifications regarding material or dimensional updates.

Edgeboard Connectors Selection Notes

Select this component when a high-density 138-position connection is required with a standard 2.54mm pitch. The vertical orientation and panel mount style are suitable for applications needing direct board insertion into a chassis. The gold plating offers corrosion resistance for long-term reliability. Consider the wire wrap requirement as it dictates the manufacturing assembly process compared to surface mount alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 895 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles, catering to various industrial and commercial electronics needs. The 895 series typically employs PPS insulation for high-temperature performance and uses gold-plated contacts for signal integrity. This specific model represents a high-count variant within the lineup.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 895 Series Ordering Guide for alternative position counts or flange configurations. Verify if other distributors list equivalent parts under different catalog numbers. Ensure any substitute maintains the same 2.54mm pitch and 1.57mm board thickness tolerance.
