302-048-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-048-221-201 is a dual-edge female card edge connector from the 302 series, designed for board-to-board interconnection. It features 48 positions with a 0.050-inch (1.27mm) contact spacing and two rows of contacts. The connector utilizes gold-plated cantilever spring contacts made from copper alloy, housed in a black thermoplastic polyester insulator. It supports PCB thicknesses ranging from 0.059 to 0.063 inches (1.50 to 1.60 mm). Rated for 5A current per contact, it operates within a temperature range of -55°C to +105°C and meets RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever spring contacts for reliable card insertion
• Gold-plated contacts ensure low contact resistance and corrosion resistance
• Thermoplastic polyester housing provides thermal stability and mechanical strength
• Panel mount installation style with vertical orientation for secure PCB attachment

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard double-sided cards
• Test and measurement instruments needing high-density connections
• Computer peripheral devices interfacing with expansion boards

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and spacing before ordering. Confirm compatibility with the target card thickness specifications. Ensure the procurement channel provides genuine EDAC Inc. products to guarantee performance reliability. Check for RoHS3 compliance documentation if environmental regulations apply to the final assembly. Review datasheet details for mounting hole dimensions and mating force requirements.

Edgeboard Connectors Selection Notes

Select this component when a 48-position dual-edge interface with 1.27mm pitch is required. Consider the 5A current rating and -55°C to +105°C operating range for environmental suitability. Evaluate the panel mount style against available chassis space. Compare with other 302 series variants if different pin counts or contact finishes are needed. Ensure the cantilever contact type aligns with the insertion and extraction cycle requirements of the application.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 series, which specializes in dual-edge card edge connectors. The series offers various position counts and contact spacings to accommodate different design constraints. The 302-048-221-201 specifically addresses applications requiring a moderate density of 48 contacts with a fine 1.27mm pitch. It complements other EDAC solutions by providing a standardized, reliable interconnect option for non-specific double-sided cards in industrial and commercial electronics.
