306-022-520-158

Overview

The EDAC Inc. model 306-022-520-158 is a card edge connector from the 306 Series, featuring 22 positions with a dual-edge female configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a thickness range of 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The connector employs gold-plated cantilever spring contacts for reliable signal transmission. Designed for panel mounting via flanges, it operates within a temperature range of -40°C to 105°C and uses a green thermoplastic polyester insulator.

Feature Summary

• Dual-edge female contact design accommodates non-specified double-sided PCBs
• Gold-plated cantilever spring contacts ensure secure electrical connection
• Panel mount installation with flange features for stable positioning

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Consumer electronics module interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to confirm exact pin count, termination style, and insulation color. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status and environmental certifications required for the end application. Cross-reference the manufacturer part number with distributor catalogs to avoid substitution errors.

Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required for panel-mounted applications. Consider the operating temperature range and material compatibility with the target PCB substrate. Evaluate mechanical stability needs against the flange mounting options provided by the series. Compare alternative series if different board thickness tolerances or contact row configurations are necessary.
