LDG-S Enclosure for DIN-rails
The LDG-S serie of enclosures are fully insulated enclosures
according to the specifications of the machinery and the auto-
motive industries.
Designed for easy snap-on assembly onto DIN-rails by inte-
grated snap-on clip. These enclosures facilitate economical
device assembly with optimal utilization of space. For the ter-
mination of the conductors of the cable 2 enclosure versions
are availible:
- pluggable terminals for easy servicing and exchange (com-
mercial pin headers on the pcb.
- screw terminals for a fixed termination of the conductors.
For effective heat dissipation the LDG-S enclosure features
a base part with integrated ventilation slots. Closed versions
(without ventilation slot) are availible upon request.
Technical Features
• 2 installation widths: LDG-S2: 22.5 mm
LDG-S4: 45 mm
• Options for the termination of the conductors:
LDG-S2: 4 screw terminal blocks with 4 terminals each
or
4 pcb headers with 4 pin contacts each for
connecting cable cnnectors with 4
pins
LDG-S4: 8 screw terminal blocks with 4 terminals each
or
8 pcb headers with 4 pin conacts each for
connecting cable connectors with 4 pins
• Easy snap-on assembly on DIN-rails according to
DIN EN 50 022
• Easy assembly of the enclosure achieved by snap-in
design of the two base part and the top part
• Transparent housing cover with the option for a label
• Customized colors and versions upon request
