The 15ESALM-3.81 Blade Terminal Blocks are highly adaptable plug-in blade-type terminal blocks.  Their core advantage lies in the 3.81mm standard pitch design, combined with a blade-type mating structure, resulting in uniform insertion/extraction force and lower contact resistance. Compared to traditional screw-type terminals, this significantly improves installation and maintenance efficiency. This product supports multiple pole configurations, adapts to mainstream wire gauges, and features both flame retardancy and vibration resistance, allowing it to replace ordinary terminals with the same pitch in industrial settings, reducing wiring time and fault risks.

Signal acquisition circuits for new energy charging stations


Features:
Efficient Plug-in Design: Blade-type contact structure ensures smooth insertion and extraction with a large contact area, stable signal transmission, and superior vibration resistance compared to ordinary plug-in terminals.
Precise Pitch Adaptation: 3.81mm standard pitch adapts to most industrial control PCB board layouts, eliminating the need for additional mounting hole adjustments.
Flame-Retardant and Durable Material: Plastic parts use UL94V-0 flame-retardant material, and contacts are made of high-elastic phosphor bronze, capable of withstanding a wide temperature range of -40℃ to +105℃.
Flexible Pole Selection: Supports multiple pole configurations to meet the signal and power transmission needs of different circuits, reducing the number of terminal models required in inventory.
Convenient Wiring Design: Adapts to AWG28-14 wire gauges, with standardized stripping length, allowing for quick wiring with automated tools.
