OEM ODM Barrier Terminal Blocks 7.62mm Din Rail Wired Connector
A barrier terminal block (also called a barrier strip or screw terminal) is an electrical connector used to safely and securely join multiple wires together or to connect wires to a device, using metal screws as the clamping method. It is characterized by a solid insulating plastic body with metal clamps separated by raised plastic walls or barriers.
Key Advantages
- Safety: Barriers prevent shorts between adjacent connections
- Reliability: Screw clamps provide strong, vibration-resistant connections suitable for high-current applications
- Flexibility: Easy to add, remove, or change wires using only a standard screwdriver
- Organization: Neatly organizes multiple connections in defined spaces
- Tool Simplicity: Requires only standard screwdriver for installation
- High Power Capacity: Handles higher current and voltage than simpler connectors like wire nuts or IDC blocks
Common Applications
- Industrial Control Panels (PLC Panels) for power, sensors, and actuators
- Power Supply input and output connections
- Motor Controllers and Drives for main power and control
- Heating, Ventilation, and Air Conditioning (HVAC) equipment
- Appliance Wiring in ovens and industrial machinery
- Audio Equipment for robust connections in amplifiers and speakers
- Electrical Distribution in sub-panels and junction boxes
