Terminal blocks are components used for electrical connections, mainly used to safely and reliably connect wires or cables to circuits or devices.

Terminal modules are a modular electrical connection solution commonly used in industrial automation, control systems, power distribution cabinets, power management, PLC (Programmable Logic Controller) interfaces and other scenarios.

The PCB mounting bracket is a supporting component used to fix the printed circuit board to ensure that the circuit board is stably installed in the equipment or chassis to prevent vibration, displacement or short circuit.
