Terminal Blocks - Panel Mount

1. Overview

Panel Mount Terminal Blocks are modular electrical connectors designed for permanent mounting on control panels or equipment chassis. They facilitate secure and organized termination of wires in industrial applications. These components play a critical role in ensuring reliable electrical connectivity, enabling efficient signal and power distribution across systems.

2. Main Types & Functional Classification

TypeFunctional FeaturesApplication Examples
Screw Terminal BlocksMechanical clamping via screws, high current capacityIndustrial machinery control panels
Spring Cage Terminal BlocksTool-free wire insertion, vibration resistanceAutomotive testing equipment
PCB Terminal BlocksDirect printed circuit board mountingMedical diagnostic devices
DIN Rail Terminal BlocksStandardized rail mounting, modular expansionFactory automation systems

3. Structure & Components

Typical construction includes: - Insulating housing (PA66/Glass Fiber) - Conductive elements (Copper Alloy/Brass) - Mounting flange with M4/M6 threaded holes - Wire entry system (Axial/Radial orientation) - Locking mechanisms (Screw/Spring Clamp)

4. Key Technical Specifications

ParameterImportance
Rated Current (10-300A)Determines power handling capability
Working Voltage (250-1000V)Defines electrical insulation requirements
Wire Size Range (0.14-35mm )Dictates application flexibility
Material Flame Rating (UL94 V-0)Safety compliance factor
Operating Temperature (-40 C to +120 C)Environmental endurance indicator

5. Application Fields

Primary industries include: - Industrial Automation (PLC control cabinets) - Energy Systems (Solar inverters) - Transportation (Railway signaling) - Building Technology (HVAC controllers) - Test & Measurement (Lab equipment)

6. Leading Manufacturers
