Edgeboard Connectors datasheet and documents for 305-052-521-268

305-052-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-052-521-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 52 positions arranged in a dual row with a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy half-beam spring type, rated for 5 A continuous current and 1800 VACrms insulation voltage. It accepts non-specified dual-edge cards within a thickness range of 1.37 mm to 1.78 mm. The thermoplastic housing is green, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure positioning
Utilizes half-beam spring contact design for reliable signal transmission
Features gold-plated copper alloy contacts for corrosion resistance

Edgeboard Connectors Applications

Industrial control systems requiring robust interconnects
Telecommunications equipment backplanes
Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure compatibility with required polarizing key configurations and card thickness tolerances. Confirm that the 1800VACrms rating meets system isolation requirements. Cross-reference the 52-position count and 3.96mm pitch with PCB layout specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-voltage rated, dual-row card edge interface is required for panel-mounted applications. Ensure the host PCB accommodates the vertical orientation and the specific 1.37–1.78 mm card thickness window. Consider the availability of compatible polarizing keys if mechanical alignment is critical for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their high voltage ratings and durable construction. The series supports various position counts and is widely used in environments demanding stable electrical connections under thermal stress.
