305-040-555-202

Edgeboard Connectors Overview

The EDAC Inc. 305-040-555-202 is a standard card edge connector from the 305 Series, designed for vertical panel mounting applications. It features a dual-row configuration with 40 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The insulator body is made of green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low-profile insulator body design for compact integration
• Utilizes half-beam contact type for robust mechanical retention

Edgeboard Connectors Applications

• Vertical panel mount interconnect systems
• Dual-edge card edge PCB connections
• Industrial control module interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange characteristics and termination style. Confirm compliance with RoHS3 and REACH regulations as specified by the manufacturer. Ensure the selected variant aligns with the intended polarizing key requirements and board thickness specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and 1800 VACrms dielectric strength for appropriate electrical isolation needs. Verify compatibility with the target PCB thickness of 1.57 mm and check if between-contact or in-contact polarizing keys are necessary for the assembly design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of card edge connectors, which offer various mounting options and row spacings. The series is characterized by its ability to accept polarizing keys and support dual-edge card configurations. Similar parts in the series include variants with different position counts and flange styles, such as the 305-040-521-202.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series may include parts with identical positioning but different flange configurations, such as 305-040-521-202. Verify that any replacement maintains the 3.96 mm pitch, 40-position count, and vertical mounting orientation to ensure mechanical and electrical compatibility.
