1. Robust Design: Engineered for Harsh Environments
The E-Series is defined by its high-grade engineering plastic shell, offering superior corrosion resistance compared to traditional metal connectors.
- IP67 Waterproof Rating: Ensures complete protection against dust and temporary immersion in water.
- Dual Locking Mechanisms: Depending on your application, choose between the traditional Screw Thread for maximum security or the Bayonet Coupling for rapid maintenance.
2. The Product Lineup: From Compact E7 to Heavy-Duty E16
Each sub-series in the E-line is designed for specific spatial and functional requirements:
- E7 Series (7/16-28UNS): The most compact circular connector, offering 2-6 pins for space-constrained sensors.
- E10 Series (5/8-27UNS): A versatile "all-rounder" with 2-12 pins, perfect for general industrial use.
- E13 Series (13/16-28UNS): The platform for complexity, supporting up to 18 pins for multi-signal wiring.
- E16 Series (1-20UNEF): Optimized for efficiency with a snap-on bayonet lock and up to 22 pins, reducing downtime during device swaps.
3. Beyond Power: Integrated Data Solutions (5G, HDMI, Type-C)
What sets the STA E-Series apart is its ability to integrate modern data protocols into a rugged waterproof form factor:
- 5G & Ethernet (E-RJ45): Specifically designed for 5G base stations and industrial IoT, ensuring high-speed data integrity.
- High-Definition Video (E-HDMI): Brings waterproof HD video transmission to medical imaging and industrial monitoring.
- Power Delivery (E-Type-C): A compact E10-sized solution for high-current charging in portable medical or testing devices.
- Optical Fiber (E-FDDI): Low-loss transmission for long-distance, EMI-heavy environments.
- Legacy Support (E-D-SUB): Waterproofing older industrial equipment without needing a complete system overhaul.

4. Diverse Applications: Powering Multiple Industries
