895-144-555-503

Edgeboard Connectors Overview

The EDAC Inc. 895-144-555-503 is a standard card edge connector receptacle featuring 144 positions arranged in a dual row configuration. It utilizes a 2.54 mm (0.100 inch) pitch and is designed for panel mount installation with a right-angle orientation. The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. The housing is made of polyphenylene sulfide (PPS), providing durability and thermal stability. This component supports a maximum operating temperature of +125°C and a minimum of -40°C, with an insulation resistance of 5 GOhms and a current rating of 3 A.

Edgeboard Connectors Feature Summary

• Dual-row female card edge design accommodating 144 contact positions
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Polyphenylene sulfide (PPS) housing material for high thermal stability
• Right-angle panel mount configuration for space-efficient integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Medical devices needing reliable high-density interconnects
• Automotive electronics applications with strict environmental tolerances

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure that the right-angle mounting style aligns with the mechanical constraints of the target enclosure. Cross-reference the 144-position count with the dual-row layout to prevent mating errors with single-row counterparts. Confirm RoHS compliance status through the manufacturer's latest certification documents before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density 144-position interface is required with a standard 2.54 mm pitch. The right-angle panel mount style is suitable for applications where vertical clearance is limited but horizontal board space is available. The PPS housing and gold contacts make it appropriate for environments demanding long-term reliability and resistance to oxidation. Consider the 3 A current rating and 125°C temperature limit to ensure compatibility with the system's electrical and thermal profiles.
