Overview
The EDAC Inc. 306-021-500-102 is a standard card edge connector header within the 306 series, designed for vertical panel mount applications. It features 21 positions with a contact spacing of 3.96 mm (0.156 inches) and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are gold-plated copper alloy, rated for 5 A current, and utilize solder lug termination. The insulator body is constructed from thermoplastic material.
Feature Summary
- Vertical panel mount configuration with low profile insulator body
- Gold-plated copper alloy contacts for reliable signal transmission
- Accepts standard 0.062 inch nominal thickness PCBs
Applications
- Industrial control systems requiring robust card edge interfaces
- Telecommunications equipment backplanes
- Test and measurement instrumentation modules
Procurement Notes
Verify the specific ordering suffix to confirm contact plating thickness and insulation material composition, as these attributes define the electrical performance and environmental resistance of the component. Ensure that the selected variant matches the required PCB thickness tolerance of 1.57 mm to guarantee proper mechanical engagement and contact retention during operation.
Selection Notes
Select this connector when a single row of 21 positions is required for vertical mounting. Confirm that the mating card edge board adheres to the specified 0.062 inch thickness standard. Evaluate the 5 A current rating against the application's power requirements to ensure adequate thermal management and electrical safety margins are maintained.
Part Context
This component belongs to the EDAC 306 series of standard card edge connectors, which provides a range of position counts and configurations. The series is characterized by its use of thermoplastic insulators and gold-plated contacts, offering a balance of durability and conductivity for general-purpose electronic interconnections in various industrial environments.
Replacement Considerations
Compatible substitutes include other EDAC 306 series headers with identical 21-position counts and 3.96 mm pitch, such as the 306-021-520-102, provided they match the vertical orientation and solder lug termination style.
