1.Type and Pole

3.5: Refers to a terminal spacing of 3.5 millimeters. This is the distance between the centers of two adjacent connection points. It determines the size and wiring density of the terminals and is one of the most critical dimensional parameters. A 3.5mm spacing represents a medium density, balancing compactness and safety (sufficient creepage distance).

Screwless: Refers to the connection technology. Unlike traditional terminals that require a screwdriver for tightening, it uses spring pressure connection technology (usually referred to as "push-in spring connection" or "push-fit connection"), allowing for wiring without tools or with only a small screwdriver as a lever.

Type: Pcb Pluggable Screw Terminal Block

III. Core Advantages and Features

Compared to traditional screw-type terminal blocks, its advantages are very prominent:

Extremely fast wiring speed: No need to tighten screws; the wiring time for a single wire is measured in seconds, significantly improving wiring efficiency and saving labor costs.

Vibration-resistant and maintenance-free: The continuous pressure of the spring compensates for the deformation of the wire caused by thermal cycling, and it will not loosen in vibrating environments, ensuring high reliability.

Simple operation, no torque control required: Avoids the problems of poor contact due to insufficient torque or wire damage due to excessive torque in screw terminals, ensuring consistent connection quality.

Saves tools and space: A small screwdriver is all that's needed for operation, eliminating the need to carry multiple sizes of screwdrivers. The compact design saves space in the control cabinet.

Pluggable design: When front-end devices (such as sensors and actuators) fail, the plug can be quickly disconnected for replacement without disassembling the back-end wiring, making maintenance extremely convenient.

Wide range of applicable wire sizes: Typically, one terminal can accommodate a range of wire diameters (e.g., 0.2mm² to 2.5mm²), reducing the variety of materials needed.
