1. Core Model List (With Product Descriptions)

2. Quick Interpretation of Model Naming Rules

Mastering the naming logic can help you quickly identify the core parameters and applicable scenarios of the product:

1. Series Prefix
   • UTN: Heavy-load terminal series, dedicated to high-power industrial main circuit connection, with a single 35-spec model.
   • UTME: Basic medium-load terminal series, focusing on 6-spec general circuit connection.
   • UTI: Function-enhanced terminal series, integrating grounding, phase identification and other extended functions, covering 35/16/2.5 specs.
   • UT ME: UT ME series is a derivative of UT series, adding PE grounding function on the basis of UTME 6.
   • UT: The core series of this batch of models, covering a full range of specs from 1.5 to 35, with rich multi-channel and functional configurations.
2. Core Specification ParameterThe number after the series prefix (35/16/10/6/2.5/1.5) represents the core current-carrying specification of the terminal. The larger the value, the higher the current-bearing capacity, corresponding to high-power, medium-power and low-power circuit scenarios respectively.

   • MT/MTD: Terminal structure type, MT for multi-terminal dense wiring, MTD for integrated DIO digital interface, suitable for industrial automation systems.
   • DIO/R-L/L-R: Digital input/output interface with signal direction identification, realizing precise signal transmission in control systems.
   • P/P: Dual polarity identification, suitable for dual-polarity circuit connection scenarios.
   • HESILED 24 (5X20): 24V HESI LED status indicator with 5×20mm size, providing visual circuit status feedback.
   • 3PV: Photovoltaic system adaptation, tailored for small-power photovoltaic circuit wiring.
   • 1P: Single-circuit configuration, suitable for independent single-circuit connection.
4. Color Suffix Mark
   • BU/BK/GN/RD/OG/WH: Color coding, blue for signal circuits, black for general circuits, green for grounding circuits, red for power circuits, orange for warning circuits, white for auxiliary circuits, facilitating quick identification in complex wiring systems.
