302-120-321-201

Edgeboard Connectors Overview

The EDAC Inc. model 302-120-321-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 120 positions arranged in two rows with a contact spacing of 0.050 inches (1.27 mm). The connector utilizes female contacts with gold plating and is housed in black polyamide (PA66) insulation. It supports PCB thicknesses ranging from 0.051 to 0.071 inches (1.30 mm to 1.80 mm) and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 120 total positions for high-density signal routing
• Gold-plated cantilever spring contacts ensure reliable electrical connection
• Black PA66 housing provides thermal stability and mechanical durability
• Designed for through-hole mounting on non-specified dual-edge cards

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Medical device internal circuit boards
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, contact plating thickness, and termination style. Ensure compatibility with the target PCB edge card thickness specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, dual-edge connector is required for space-constrained designs. The 0.050-inch pitch allows for dense I/O arrangements while maintaining standard mounting dimensions suitable for vertical panel or chassis integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in standard card edge connectors. The series offers various position counts and configurations, providing a scalable solution for connecting printed circuit boards to system backplanes or motherboards in diverse electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that alternative parts match the 120-position count, 1.27mm pitch, and dual-edge interface requirements to ensure mechanical and electrical interchangeability.
