General
The LDG-A series of enclosures are fully insulated enclosures.
The screw clamp terminals are protected against accidental
contact in accordance with VDE 0100 Part 570, VDE 0160
Part 100 and VBG 4.
Designed for easy installation, these screw terminals can be
soldered by wave, allowing the manufacturing of the PCB
boards in one step.

The base for all applications
Fully-insulated enclosures in accordance with machinery
and automotive industry standards, with shockproof
terminals acc. to VDE 0100 and VBG 4.
Base part optionally with or without ventilation slots.
Enclosure surface with erosion-structure in attractive design.
Easy assembly and disassembly for servicing.
Easy connecting technique
From the connection cable via the terminal block to the
PC board, the connection could not be more simple.
Generously dimensioned stacking compartment
Printed circuit boards can be stacked one above the other
such that complex assemblies can be implemented in
compact dimensions.
Fast component-mounting and manufacturing times
The PC board, with the mounted components and terminal
blocks will be wave-soldered, in one work process and
then completely assembled into the base part in one step.
