The interface terminal block (round / spade terminal type) is a component for wiring connections that combines a connector and a small circuit board terminal block. It is mainly used to connect a PLC, etc., and to reduce the size of the control panel. There are two types of crimp terminals: a basic round type and a Y type that can be removed simply by loosening the screws. The connector types are divided into MIL, FCN, MR, Centronics, etc. Terminal block screws include M3, M3.5, etc. The mounting method can be selected from direct mounting and mounting on a DIN rail. Since the terminal pitch, compatible devices, and representative standards differ depending on the product, it is necessary to select an appropriate interface terminal block (round / spade terminal type) according to the application. There are also support screw type products that can keep the screws loosened, and products that allow you to select a name plate.
