305-058-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-058-555-508 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features a 58-position configuration with a 3.96 mm pitch and supports two rows of contacts. The component utilizes gold-plated copper alloy terminals and a thermoplastic housing. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The connector accepts between-contact and in-contact polarizing keys and accommodates PCB thicknesses of 1.57 mm.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm terminal type and plating specifications. Ensure that the selected variant matches the required polarizing key compatibility and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability and compliance with RoHS directives before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector based on the requirement for a 58-position dual-row interface with a 3.96 mm pitch. Confirm that the application environment falls within the specified -40°C to +105°C operating temperature range. Verify that the PCB design accommodates the 1.57 mm board thickness and that the system voltage does not exceed the 1800 VACrms insulation rating. Ensure mechanical mounting constraints align with the panel installation style.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is engineered for robust performance in demanding environments, featuring standardized dimensions and high-current capabilities. The 305-058-555-508 specifically addresses needs for high-pin-count dual-edge connections with secure locking mechanisms.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching pin counts and pitch, such as the 305-048-555-508 or 305-018-555-508, provided the position count differs. Verify that any replacement maintains the same 3.96 mm pitch, dual-row layout, and gold plating specifications to ensure mechanical and electrical compatibility.
