305-014-521-204

Edgeboard Connectors Overview

The EDAC Inc. 305-014-521-204 is a dual-sided card edge connector from the 305 Series, featuring 14 positions with a 0.156-inch (3.96mm) pitch. It utilizes half-beam contact types for reliable signal transmission and accepts between-contact or in-contact polarizing keys. The connector supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). It offers a 5A continuous current rating and 1800VACrms dielectric withstanding voltage. The unit is panel-mounted via solder tails and operates within a temperature range of -40°C to 105°C.

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual-sided configuration with half-beam contacts for robust connection
• Gold-plated terminals on copper alloy substrates for corrosion resistance
• Thermoplastic polyester insulation housing for thermal stability

Edgeboard Connectors Applications

• Industrial control system interconnections
• Medical device circuit board interfaces
• Agricultural technology equipment connections
• General-purpose vertical panel mounting applications

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct flange and tail specifications. Confirm that the required polarizing key type matches the connector's acceptance capabilities. Check RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a 14-position dual-sided interface with a 3.96mm pitch is required. Ensure the target PCB thickness falls within the 1.37mm to 1.78mm operational range. Consider the 5A current rating and high dielectric strength for demanding electrical environments. Verify compatibility with existing polarizing key systems if mechanical locking is necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors designed for vertical panel installation. The series provides various position counts while maintaining consistent 0.156-inch spacing. These connectors are engineered for durability in harsh environments, including medical and agricultural sectors, offering reliable performance across wide temperature ranges.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-014-521-202 and 305-014-521-204 variants with differing suffixes. Verify that any replacement maintains the identical 14-position count, 3.96mm pitch, and dual-sided configuration. Ensure mechanical dimensions and flange characteristics match the original design constraints.
