In the fast-moving world ofindustrial automation, every control signal, sensor, and relay depends on a stable and secure electrical interface. ForPLC systems, relay boards, and I/O modules, the5.08mm pitch PCB terminal blockis the industry’s preferred standard due to its balance of compactness, reliability, and voltage clearance.

As a dedicatedPCB terminal block manufacturer,Ningbo Zhongbo Photovoltaic Technology Co., Ltd.delivers certified, durable 5.08mm terminal blocks widely used inindustrial control panelsandautomation PCBs.

⚙️ Why 5.08mm Pitch for Industrial Control Boards?

5.08mm spacing is optimal for:

  • Handling 300V+ control signals safely

  • Supporting 12–24 AWG wires for relays, sensors, and actuators

  • Ensuring sufficient clearance to prevent arcing or overheating

  • Easy integration intoDIN rail-mounted devicesand modular PLC cards

Zhongbo’s terminal blocks offer:

  • High torque resistance

  • Secure screw or pluggable connection options

  • Compatibility withautomated soldering processes

🔩 Key Models for Automation PCBs

  • ZB128-5.08– Ideal for PLC control and relay logic boards

  • 2EDGK-5.08– Pluggable block for modular signal interface boards

  • ZB129-5.08– Screw terminals for reliable mechanical/electrical connection

  • 2EDGKA-5.08– Compact pluggable type for slimline control cards

All Zhongbo models are manufactured using:

  • Flame-retardant PA66 UL94V-0 housing

  • Corrosion-resistant tin-plated brass contacts

  • PCB pin plating to ensure long solder joint life

🏭 Applications in Industrial Environments

Zhongbo’s 5.08mm terminal blocks are widely used in:

  • PLC control panels
