2EDG KM 3.5mm 3.81mm Pluggable PCB Terminal Block — 300V 10A Plug-In Connector
2EDG / KM 3.5mm & 3.81mm Pluggable PCB Terminal Blocks — 300V/10A Industrial Plug-In Wire Connectors
The 2EDG/KM 3.5mm and 3.81mm pluggable PCB terminal blocks combine the 300V/10A industrial rating of fixed 3.5mm/3.81mm screw terminal blocks with the plug-in/plug-out serviceability of the 2EDG two-part connector system. This makes them the ideal choice for industrial control boards, PLC I/O modules, and automation equipment where field wiring must remain connected while the PCB is removed for maintenance or replacement. The male header is soldered to the PCB; the female plug with field wiring simply unplugs as a unit.

Frequently Asked Questions
Q: What is the difference between 2EDG and KM series pluggable terminal blocks?
A: 2EDG and KM are trade names for the same pluggable terminal block system from different manufacturers. Both use a two-part male header + female plug design with the same 3.5mm or 3.81mm pitch and are dimensionally interchangeable.
Q: Are 3.5mm and 3.81mm pluggable blocks interchangeable?
A: No. 3.5mm and 3.81mm are different pitches with different PCB footprints. Verify your PCB footprint before ordering.
Q: Can the female plug be inserted/removed under power?
A: Hot-plugging is not recommended. Always de-energize the circuit before inserting or removing the female plug to prevent arcing and contact damage.
