Description
Expansion cable, 0.4 m length, used to connect an XGT/XGB CPU to an expansion base or module. Small, fixed-length cable for short linkage inside compact panels.
The Polar Energy Assessment:
The E041 is a 0.4-metre CPU expansion cable designed for short, direct connections between the main CPU/base and its expansion chassis. Use it when the CPU and adjacent expansion base are mounted close together; the XGT family manual lists the E041 as the 0.4 m option and notes total extension distance limits for system design.
Pros
- Minimal slack, tidy wiring for compact panels.
- Simple, plug-and-play connector matched to XGT/XGB expansion bus.
Limitations
- Too short for anything but nearby expansion bases; you’ll need a longer cable if components are spaced.
Typical use cases
- Compact control panels where CPU and first expansion base sit side by side.
