In the world of AV, the importance of a solid, reliable connection cannot be overstated. When a signal path fails, the show stops. That’s why choosing the right connector for your equipment is a critical step in any design or build. Io Audio Technologies’ E-Series XLR chassis connectors are designed to provide a cost-effective, high-density solution that doesn’t compromise on quality or performance.

What Are E Series Chassis Connectors?

The E Series is a line of XLR-style chassis connectors that are specifically designed for direct termination onto a printed circuit board (PCB). Unlike traditional connectors that require individual soldering of wires, the E Series features a compact plastic body with pins that are soldered directly to the circuit board. This streamlined design is what makes them an ideal choice for a variety of modern AV applications where space is at a premium.

Key Features and Options

The E Series offers several key features that set it apart:

• Compact Footprint & High Packing Density: The small size of these connectors allows for a higher number of connections in a limited space. This is a significant advantage for designers of compact audio gear, lighting controllers, and other equipment where every millimeter counts.
• Gold Plated Contacts: All E Series connectors come with gold-plated contacts. This plating is crucial for preventing corrosion and ensuring a clean, low-resistance connection over the long life of the connector.
• Durable, All-Plastic Housing: The connectors feature a rugged, all-plastic housing that is both lightweight and durable. This material is also UL94-V-0 rated, meaning it has been tested to be highly flame-retardant.
• Male and Female Options: The series is available in both male and female configurations, allowing for a variety of input and output configurations on your equipment.
• Vertical and Horizontal Mounting: A standout feature of the E Series is the choice between vertical and horizontal PCB mounting. This flexibility gives designers the freedom to lay out their circuit boards in the most efficient way possible, whether they need to save vertical space or fit into a specific chassis design.
• Multiple Pin Counts: The E Series is available in 3, 4, or 5 pin configurations, making them suitable for a variety of applications.
• Separate Ground Pin: The connectors also include a separate nickel-plated brass ground pin, which ensures proper grounding to both the mating connector and the equipment panel.
