305-018-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-018-520-502 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features an 18-position dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector supports a board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A current, it employs solder lug termination for secure PCB attachment. The housing is constructed from thermoplastic material, providing electrical insulation with a resistance of 5 GOhms. This component operates within a temperature range of -40°C to +105°C, suitable for various industrial applications requiring robust connectivity.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 18-position count and 3.96 mm pitch before procurement. Confirm that the solder lug termination type aligns with the target printed circuit board layout and assembly process. Ensure the operating environment temperature falls within the specified -40°C to +105°C range. Check for RoHS compliance requirements if applicable to the final product regulations. Validate that the panel mounting style fits the enclosure design constraints.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row card edge interface with a 3.96 mm pitch is required. The 18-position count suits applications needing moderate channel density without excessive board space usage. The vertical panel mount option is ideal for chassis-based designs where direct board-to-board connection is not feasible. Consider the 5 A current rating to ensure adequate power handling for the intended signals. The thermoplastic housing offers durability for repeated insertion cycles typical in modular systems.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their 3.96 mm pitch and versatile mounting options. The series includes various position counts and termination styles to accommodate different design needs. The 305-018-520-502 specifically addresses the need for a 18-position dual-row connector with solder lug termination. It is part of a broader family of connectors used in industries demanding high reliability and standardized form factors.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with identical pitch and row configuration but different position counts, such as 305-038-520-502 or 305-048-520-501, provided the pinout and mechanical fit allow for adaptation. Verify that any replacement maintains the 3.96 mm pitch and dual-row structure to ensure functional equivalence.
