SMH SBE320 Power Connector Introduction

  • Apr 10, 2025

Here’s a full introduction to the SBE320 connector, a heavy-duty, industrial power connector used in demanding applications:


🔌 SBE320 Connector – Overview

The SBE320 is a high-current, two-pole connector, designed for 320 amps of continuous current at up to 150V DC. It’s commonly used in industrial battery systems, electric vehicles, and power distribution setups that demand reliable, high-amperage connections.

It’s closely related to the SY series (like SY350), but with integrated auxiliary contact support, making it more suitable for intelligent power systems.


⚙️ Key Features

  • High Current Rating: Supports up to 320A continuous with appropriate cable size.

  • Voltage Rating: Designed for up to 150V DC, meeting UL and industrial requirements.

  • Integrated Auxiliary Contact Support: Supports auxiliary contacts for temperature sensors, CANbus, or interlock signals (ideal for smart battery systems).

  • Color-Coded Housings: Available in various colors to indicate voltage level (e.g., red, blue, gray, green), with mechanical keying to prevent mismatching.

  • Durable Construction: Flame-retardant UL94 V-0 polycarbonate housings for use in rugged environments.

  • Genderless Design: Connects to identical units—no male/female distinction—simplifying installation and reducing inventory types.

  • Mechanical Keys: Prevent cross-connection of different voltage systems (color and keying must match to mate).

  • High Mating Cycles: Rated for >10,000 connection cycles, suitable for battery swap systems.


🔋 Common Applications

  1. Electric Forklifts & Material Handling Equipment

  2. Battery Chargers

  3. AGVs (Automated Guided Vehicles)

  4. Modular Battery Packs

  5. Heavy-duty DC Power Systems

  6. Industrial UPS Systems

  7. Solar & Off-Grid Systems (where smart battery interlocks are needed)
