306-009-521-158

Edgeboard Connectors Overview

The EDAC Inc. 306-009-521-158 is a dual-edge female card edge connector from the 306 Series, designed for panel and through-hole mounting. It features 18 positions with a 0.156-inch (3.96mm) contact spacing and gold-plated cantilever contacts. The unit accommodates non-specified dual-edge cards within a thickness range of 0.054 to 0.070 inches (1.37mm to 1.78mm). Constructed with a green thermoplastic polyester insulator, it supports operation between -40°C and 105°C. The connector includes a flange with top openings and 4-40 threaded inserts for secure installation.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever spring contacts
• Panel mount design with integrated flange and threaded inserts
• Gold-plated terminals for reliable signal transmission
• Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Medical device circuit board connections
• Agricultural technology equipment interfaces
• General-purpose double-sided PCB mounting

Edgeboard Connectors Procurement Notes

Verify the specific pin count and contact spacing against the target PCB layout before ordering. Confirm that the host board thickness falls within the specified acceptance range to ensure proper mechanical engagement. Check for RoHS compliance requirements if the application demands restricted substance adherence. Ensure the mounting hole pattern matches the flange specifications for correct panel integration.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-density connection is required for double-sided edge boards. The 0.156-inch pitch offers a balance between density and ease of manufacturing. Consider the flange mounting style if vibration resistance and precise alignment are critical. Verify that the operating temperature range meets the environmental conditions of the final assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series is known for its durability and suitability for harsh environments, including medical and agricultural applications. The 306-009 variant specifically denotes an 18-position configuration, distinguishing it from other pin counts in the same family while maintaining consistent electrical and mechanical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 18-pin count, 3.96mm pitch, and dual-edge female interface. Compatible alternatives should offer similar flange mounting options and gold-plated contact finishes. Verify that any replacement part supports the same PCB thickness range and operates within the required temperature spectrum.
