2EDG 2.54mm Pluggable PCB Terminal Block — Plug-In Wire Connector 150V 6A
2EDG 2.54mm Pluggable PCB Terminal Blocks — Tool-Free Plug-In Wire Connectors for Compact PCBs
The 2EDG 2.54mm pluggable PCB terminal block is a two-part connector system consisting of a PCB-mounted male header (socket) and a field-wireable female plug that can be inserted and removed without tools. This plug-in design is the critical advantage over fixed screw terminal blocks: the PCB can be removed from the enclosure for servicing without disconnecting any field wiring — the wired plug simply unplugs from the PCB header. This makes 2EDG pluggable terminal blocks the preferred choice for industrial equipment requiring frequent maintenance, modular control systems, and any application where PCB serviceability is a design requirement.

Pluggable vs Fixed Terminal Blocks — Key Advantage
Unlike fixed screw terminal blocks where wires must be disconnected to remove the PCB, pluggable terminal blocks allow the entire wired connector to be unplugged as a unit. This enables: faster PCB replacement in the field, easier factory testing before wiring, modular system assembly, and reduced risk of wiring errors during maintenance. For any system where the PCB may need to be replaced or serviced independently of the field wiring, pluggable terminal blocks are the professional choice.
Ideal Applications
- Industrial control boards requiring field-replaceable PCBs

- Test and measurement equipment with modular PCB assemblies
Frequently Asked Questions
Q: What is the difference between 2EDG and standard screw terminal blocks?
A: Standard screw terminal blocks are fixed to the PCB — wires must be disconnected to remove the PCB. 2EDG pluggable blocks have a two-part design: the male header is soldered to the PCB, and the female plug (with wires attached) can be inserted and removed without tools, allowing PCB removal without disturbing field wiring.
Q: Are 2EDG 2.54mm pluggable blocks compatible with fixed KF128-2.54mm footprints?
A: The male header of 2EDG-2.54mm uses the same 2.54mm pitch PCB footprint as KF128-2.54mm fixed terminal blocks, making them footprint-compatible for PCB design flexibility.
Q: What screwdriver is needed for the female plug?
A: A flat-blade screwdriver with a 2.0–2.5mm blade is needed to tighten the wire clamping screws on the female plug. The plug itself inserts and removes tool-free.
